You want to take on Mitosis? Let me get your diagnosis. It says you're half the man I am. And all your raps are necrosis. Yeah I'm so perfectly perfectIn all my careful divisions. Creating identical versions. While you're "Oh I'm so different!"                                                                Don't talk to me! You've been around the block too many times. And your duplicate splitting is constantly spitting out, four daughter nuclei?                                                                          Don't be jealous cause I'm sexy and I got two sets of phases. I like to mix DNA up when I'm entering my prophase stages!                                                                                                       You're like your parents kid. Just like a clone. You see this chromosomal genetic combination's mine own!                                                                                                             I'm independent. My chromosomes don't need any pairs. At the end there's only 23, so your mom and dad can share and make. Life! Yeah I'm the one that  gives you your offspring. Though my genetic variance can create arrogance DNA's changing from New York to Beijing...                                                                                                                                        Sure, if it weren't for you. I wouldn't have kids. But if I wasn't here, then you wouldn't exist. And those babies you keep bringing up? Awwww, real cute. I'm the one that makes them grow, so you can stop cleaning their puke!!                                                                                  You're like telophase! The only thing worth admiring is your cleavage. I don't want to give half of my chromosomes up. What I've built in my nucleus is my achievement.                           I'm like telophase tooI like to kick back and unwind. But I'm secretly Anaphase, pulling you apart from inside! I repair the whole body. To make you grow big and strong. If I wanted sex cells, I would just ask your mom.                                                                                                  Hey – here's a question! Maybe you have the answer. Did you know you're the main cause for a whole bunch of cancers? Yeah, your errors. Cause a lot of conditions. Ouch! Did that burn?Better call the physician.                                                                                                             Sorry! Can't feel your burns. As I can regrow skin. I'll repair tissue, build membranes, to never let you in.                                                                                                                            Whatever! I have Meiosis 1 and of course Meiosis 2. A way more complex process, making me way better than you. Two successive divisions, 4 perfect daughter cells, each one ends up haploid. Is that your testes thanking me as well? And I was discovered first1876 to be exact. So I'm older and wiser than you and that is a fact.                                                                      My overabundance and detailed importance, makes me a bit more complex. So my discovery required, a lot more context. I come from Walther Flemming's Genius mind and observations. Look at this cutie's beard. He'd give anyone stimulation. Well one of my forefathers had the hippest glasses and peach fuzz. Gertwig was a hipster, before everybody was. You see it's me that makes the gametes so all of humanity can reproduce. Gotta strive for diversity and progress so we don't end up like you - a douche!                                                                         Hey! Hey! Hey! Both our chromosomes line up on the equator and we're mostly stuck in interphase so let's try not to be a haters. When it comes to agreeing, one thing we have at least is that both our epic journeys end in cytokinesis!!!!!!!!!

Welcome to Science Wars!                 Chemistry, Bio, Physics, Mathematical. Which field is best?                                                       I understand the force and energy. Quantum mechanics and relativity. My field is pure and they rely on me. I see the universe like nobody.                                                         You may have made fun of me in high school. For being awkward and following the rules. Now I've got lasers, Wow that's really cool! May the mass times acceleration be with you.                                                           Atoms! Entropy! Dark matter!

If you want to feel a bond, then I can give you a good reaction. The elements that make up life are my essence, are my satisfaction. All the other fields out there are so basic. Yeah, I'm the central science! Keep your i-on me, I'll get you charged.                                                       If you need me, call me up on Avogadro's number. If you leave me, take a titrant. Shove it up your acid buffer. Dopamine and serotonin will keep you good and happy. Just get your flask and a glass all set up. And begin to understand the world.                                                                                                                                             Within me, you'll find life's beauty. From genetics to ecology. Symbiosis and not division. Unless it's mitosis or the study of fission. Even if you don't pass, you'll enjoy my class. Evolution has brung us along. All species singing one song...                                                                                                                                            If you want to learn about the world I must say. I am the purest field of study you can take. Immune to misinterpretation. The blueprint of creation. The backbone of all thing science. No bias just constant augmentation. With your mind and observation. No gadgets just your logic and your time                                                                  And pi!

In nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons and/or protons). The difference in mass between the products and reactants is manifested as the release of large amounts of energy. This difference in mass arises due to the difference in atomic "binding energy" between the atomic nuclei before and after the reaction. Fusion is the process that powers active or "main sequence" stars, or other high magnitude stars.

In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.

Conservation of energy

Energy is always conserved – the total amount of energy present stays the same before and after any changes.

The pendulum

The pendulum shows the principal of conservation of energy in action. Gravitational potential energy is converted to kinetic energy and back, over and over again, as the pendulum swings.

The diagram shows a pendulum in three positions - the two the ends of it's swing and as it passes through the middle point.

When the pendulum bob is at the start of its swing it has no kinetic energy because it is not moving, but its gravitational potential energy (GPE)gravitational potential energy: The energy stored by an object lifted up against the force of gravity. is at a maximum, because it is at the highest point.

As the bob swings downwards it loses height. So its gravitational potential energy (GPE) decreases. The work done on the bob by the gravitational force (weight) pulling it downwards increases its kinetic energy. The loss of GPE = the gain in KE.

At the bottom of its swing, the bob’s kinetic energy is at a maximum and its gravitational potential energy is at a minimum - because it is at its lowest point.

As the bob swings upwards it slows down. Its kinetic energy decreases as work is done against its weight. As it gains height the gravitational potential energy increases again.

At the very top of its swing it stops for a moment. It once again has no kinetic energy, but its gravitational potential energy is at a maximum.

At all points during the swing, the total (GPE + KE) is constant.

Note that in a real pendulum the bob’s swing will become slightly lower with each swing, because some energy is lost (dissipated, ‘wasted’) through heating, due to air resistance.

Falling objects

You should be able to calculate the kinetic energy gained when an object falls from a given height.

Differences in Purpose

What is the role and purpose of mitosis and meiosis?

Though both types of cell division are found in many animals, plants, and fungi, mitosis is more common than meiosis and has a wider variety of functions. Not only is mitosis responsible for asexual reproduction in single-celled organisms, but it is also what enables cellular growth and repair in multicellular organisms, such as humans. In mitosis, a cell makes an exact clone of itself. This process is what is behind the growth of children into adults, the healing of cuts and bruises, and even the regrowth of skin, limbs, and appendages in animals like geckos and lizards.

Meiosis is a more specific type of cell division (of germ cells, in particular) that results in gametes, either eggs or sperm, that contain half of the chromosomes found in a parent cell. Unlike mitosis with its many functions, meiosis has a narrow but significant purpose: assisting sexual reproduction. It is the process that enables children to be related but still different from their two parents.

Meiosis and Genetic Diversity

Sexual reproduction uses the process of meiosis to increase genetic diversity. Offspring created through asexual reproduction (mitosis) are genetically identical to their parent, but the germ cells created during meiosis are different from their parent cells. Some mutations frequently occur during meiosis. Further, germ cells have only one set of chromosomes, so two germ cells are required to make a complete set of genetic material for the offspring. The offspring is therefore able to inherit genes from both parents and both sets of grandparents.

Genetic diversity makes a population more resilient and adaptable to the environment, which increases chances of survival and evolution for the long term.

Mitosis as a form of reproduction for single-cell organisms originated with life itself, around 3.8 billion years ago. Meiosis is thought to have appeared around 1.4 billion years ago.

Mitosis and Meiosis Stages

Cells spend about 90% of their existence in a stage known as interphase. Because cells function more efficiently and reliably when small, most cells carry out regular metabolic tasks, divide, or die, rather than simply grow larger in the interphase. Cells "prepare" for division by replicating DNA and duplicating protein-based centrioles. When cell division begins, the cells enter into either mitotic or meiotic phases.

In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.

Stages of Mitosis

What are the four stages of mitosis?

There are four mitotic phases: prophase, metaphase, anaphase, and telophase. Plant cells have an additional phase, preprophase, that occurs before prophase.

During the mitotic prophase, the nuclear membrane (sometimes called "envelope") dissolves. Interphase's chromatin tightly coils and condenses until it becomes chromosomes. These chromosomes are made up of two genetically identical sister chromatids that are joined together by a centromere. Centrosomes move away from the nucleus in opposite directions, leaving behind a spindle apparatus.

In metaphase, motor proteins found on either side of the chromosomes' centromeres help move the chromosomes according to the pull of the opposing centrosomes, eventually placing them in a vertical line down the center of the cell; this is sometimes known as the metaphase plate or spindle equator.

The spindle fibers begin to shorten during anaphase, pulling the sister chromatids apart at their centromeres. These split chromosomes are dragged toward the centrosomes found at opposite ends of the cell, making many of the chromatids briefly appear "V" shaped. The two split portions of the cell are officially known as "daughter chromosomes" at this point in the cell cycle.

Telophase is the final phase of mitotic cell division. During telophase, the daughter chromosomes attach to their respective ends of the parent cell. Previous phases are repeated, only in reverse. The spindle apparatus dissolves, and nuclear membranes form around the separated daughter chromosomes. Within these newly formed nuclei, the chromosomes uncoil and return to a chromatin state.

One final process-cytokinesis-is required for the daughter chromosomes to become daughter cells. Cytokinesis is not part of the cell division process, but it marks the end of the cell cycle and is the process by which the daughter chromosomes separate into two new, unique cells. Thanks to mitosis, these two new cells are genetically identical to each other and to their original parent cell; they now enter their own individual interphases.

Stages of Meiosis

There are two primary meiosis stages in which cell division occurs: meiosis 1 and meiosis 2. Both primary stages have four stages of their own. Meiosis 1 has prophase 1, metaphase 1, anaphase 1, and telophase 1, while meiosis 2 has prophase 2, metaphase 2, anaphase 2, and telophase 2. Cytokinesis plays a role in meiosis, too; however, as in mitosis, it is a separate process from meiosis itself, and cytokinesis shows up at a different point in the division.

Meiosis I vs. Meiosis II

See a detailed comparison of Meiosis I and Meiosis II.

In meiosis 1, a germ cell divides into two haploid cells (halving the number of chromosomes in the process), and the main focus is on the exchange of similar genetic material (e.g., a hair gene; see also genotype vs phenotype). In meiosis 2, which is quite similar to mitosis, the two diploid cells further divide into four haploid cells.

Stages of Meiosis I

The first meiotic phase is prophase 1. As in mitosis, the nuclear membrane dissolves, chromosomes develop from the chromatin, and the centrosomes push apart, creating the spindle apparatus. Homologous (similar) chromosomes from both parents pair up and exchange DNA in a process known as crossing over. This results in genetic diversity. These paired up chromosomes-two from each parent-are called tetrads.

In metaphase 1, some of the spindle fibers attach to the chromosomes' centromeres. The fibers pull the tetrads into a vertical line along the center of the cell.

Anaphase 1 is when the tetrads are pulled apart from each other, with half the pairs going to one side of the cell and the other half going to the opposite side. It is important to understand that whole chromosomes are moving in this process, not chromatids, as is the case in mitosis.

At some point between the end of anaphase 1 and the developments of telophase 1, cytokinesis begins splitting the cell into two daughter cells. In telophase 1, The spindle apparatus dissolves, and nuclear membranes develop around the chromosomes that are now found at opposite sides of the parent cell / new cells.

Stages of Meiosis II

In prophase 2, centrosomes form and push apart in the two new cells. A spindle apparatus develops, and the cells' nuclear membranes dissolve.

Spindle fibers connect to chromosome centromeres in metaphase 2 and line the chromosomes up along the cell equator.

During anaphase 2, the chromosomes' centromeres break, and the spindle fibers pull the chromatids apart. The two split portions of the cells are officially known as "sister chromosomes" at this point.

As in telophase 1, telophase 2 is aided by cytokinesis, which splits both cells yet again, resulting in four haploid cells called gametes. Nuclear membranes develop in these cells, which again enter their own interphases.

Blue Shift -
Shows (source of wavelengths) moving closer, wavelengths shift to the blue end of the spectrum.

Red Shift -
Shows (source of wavelengths) moving further away, wavelengths shift to the red end of the spectrum.

The greater the shift in wavelength, the faster the source is moving.

A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules from their characteristic spectral lines. These "fingerprints" can be compared to the previously collected "fingerprints" of atoms and molecules, and are thus used to identify the atomic and molecular components of stars and planets which would otherwise be impossible.
