Protons have a positive charge, while neutrons have a neutral or no charge. Both lie in an atom's nucleus (red and blue in the image).
The number of protons an atom has will determine what kind of element it is. Hydrogen, for example, has 1 proton. If you added one more, the atom would turn into a Helium particle.]]> 2023-04-19 16:06:44 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560412467 Electrons belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560419482 Electrons are a subatomic particle that makes up an atom. They have a negative charge, and attract protons, since they have a positive charge. This is why atoms form, because the subatomic particles bond.
In an element, there is usually the same amount of protons as there is electrons, if an atom is neutral. The elements of the periodic table, for example, are. If it has one more or one less electron, its called an ion. ]]> 2023-04-19 16:12:32 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560419482 Ion belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560433445 Ions are classified into two: Cations and Anions. Cations are positive ions, which means they have less electrons. Wait... less? Yes! this is because electrons are negative, so Cations, positive ions, mean fewer electrons, while Anions, negative ions, mean more electrons. ]]> 2023-04-19 16:23:45 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560433445 . belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560436359 2023-04-19 16:26:00 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560436359 Isotopes belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2560442326 Isotopes happen when the amount of neutrons is different than what it should be, whether that is for more or less.

This is made up of atomic or subatomic particles, such as isotopes, alpha particles, and beta particles.

Electromagnetic radiation consists of rays. This would be UVC, gamma rays, and x-rays.

Before the big bang, there was nothing.
Milliseconds after, electrons and quarks were formed. A little bit after, protons and neutrons were formed.
At this time, the universe was still too hot for atoms to form, since electrons had too much energy and couldn't bond with protons and neutrons. ]]> 2023-04-20 17:45:57 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2562224589 Quarks belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2565897194 A quark is a elementary particle that makes up protons and neutrons.
There are 6 types of quarks: up, down, strange, charm, bottom, and top. It is through combinations of different types of quarks that hadrons, such as protons and neutrons, are formed. For example, protons are made up of two up and 1 down.
Quarks are indivisible, which means that they are fundamental and cannot be broken down into anything smaller. ]]> 2023-04-24 15:30:20 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2565897194 Bosons belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2565962419 Our universe is filled with bosons, which are particles that transport forces and energy.]]> 2023-04-24 16:15:49 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2565962419 Leptons belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2565962757 There are 6 types of Leptons, three negative and three neutral.

It didn't take long to atom nuclei to form... but electrons couldn't yet join them, as the world was way too fast and the electrons were moving too quickly.
Only after 380,000 did atoms form completely. The first elements to form were hydrogen and helium.

In the film, the astronaut's spaceship breaks down on a planet where 1 hour equals 7 years back on Earth, and when the team finally manages to leave they find that it has been 23 years.

Having previously discussed space, we talked about why we could move through space in every direction (front back up down left right) and time in one: forward. We cannot travel to the past. All of the proven equations we have relating to our world do not include time in them... why is that? Is it possible that time isn't actually real on a fundamental level?

They simulated the atmosphere thought to surround earth at the time, and then used electrical sparks to simulate lightning. Passing the gases through cold water, they condensed them and collected samples. Turns out, the sparks caused new compounds to form, such as amino acids or purines.

These nucleotides don't like being alone, so they bond. However, they don't all bond between each other. There are only two combinations: A and T, and C and G. This is because they have the same amount of bonds as each other, meaning they join each other better. ]]> 2023-04-26 16:33:46 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2569073042 Mutations belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2575475056 Mutations happen all the time; they can be good or bad. Mutation happens when a nucleotyde is added, deleted, or replaced. Some things that can cause mutation are radiation, such as UV light. Smoking can also trigger mutation.
If relatives procreate, there is a higher likelihood for there to mutation, because if there is a recessive diesease running in the family, the diesease will be more likely to develop.]]> 2023-05-02 16:41:48 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2575475056 Skin color and mutations belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2575486817 Our skin color fluctuates depending on how much melanin we have. People with lighter skin colors have less melanin, while people with darker skin have more. Melanin acts as a natural sunscreen, protecting your skin from radiation and therefore mutation, meaning that people with darker skin have less likelihood of developing skin cancer.
As your body gets exposed to sunlight, it starts producing melanin to protect your body from the radiation. This is why we get tanned!]]> 2023-05-02 16:49:22 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2575486817 Connection to english class and diversity belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2575487831 Your skin color gets determined by melanin.
People are racist over melanin.
Its honestly so ridiculous. Being out in the sun adds melanin to your skin. Does that mean that someone who is out in the sun for enough time will become inferior because their skin has become darker?
Skin colors are products of natural selection. Its a part of nature, and, originally, it was meant to help us survive. Nowadays, we are all mixed up and able to live any lifestyle independant of our skin colors.

Melanin doesen't matter. ]]> 2023-05-02 16:50:09 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2575487831 Insertion or deletion belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2578425392 The worse a mutation can be is either insertion or deletion. This is because it affects the whole chain of nuceotides: if you add or remove one nucleotide, the codons all change, because they move one over to the left or to the right (depending on whether its insertion or deletion).]]> 2023-05-04 15:03:13 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2578425392 Alleles belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2578805940 Alleles are one or more versions of a genetic sequence. They are located in chromosomes and can be dominant or recessive. Blue eyes, for example, are a recessive allele, while brown eyes are dominant. This results in a much larger chance of a child having brown eyes when their parents have one of each.
Genotypes are variations of a gene. They are each composed of two alleles, one from your mother and one from your father. ]]> 2023-05-04 20:30:03 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2578805940 Natural selection belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2578811086 Adaptation happens through mutations.
Mutations are completely random; sometimes they are good, and sometimes they are bad. Natural selection basically means that if a trait is good, it will end up being incorporated into the species.
If a trait is good for the survival of a species, that will mean that it aids in the survival of an animal and helps it live longer, meaning it will be able to reproduce more, passing down this trait to its offspring. This chain will continue for hundreds of years until its incorporated in the species.
Meanwhile, if the trait is bad, the animal will usually die off and not live long enough to reproduce. ]]> 2023-05-04 20:37:04 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2578811086 UV radiation belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2582217952 As said, UV radiation could cause skin cancer. However, this only develops later in life, so it wouldn't make sense for natural selection to act upon this.
Actually, UV radiation can impact the production of a chemical which is essential for procreation. Melanin protects your organs from this, so that the chemical can still be produced.
On the other side, though, UV helps your body create vitamin D, a vitamin that aids with bone strength and your immune system. People who lived in places where UV didn't reach them as easily adapted to having lighter skin that absorbs UV better. ]]> 2023-05-08 15:02:42 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2582217952 belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2588847469

An example of this is the Rwandan genocide.
The root of this terrible massacre was around the end of World War II, when Rwanda became Belgium's colony. To exert power over the Rwandan people the Belgian government created a divide between the previously united Rwandans. This included three groups: the Tutsi, the Hutu, and the Twa. Belgium put the Tutsi in the government and left.
For a really long time, the Tutsi discriminated against the Hutu. All three groups were the same race and looked almost identical, but because they were told they were different, they believed it and the Tutsi thought they were superior. There started to be a lot of resentment between the two main groups Tutsi and Hutu.
The Tutsi, when seeing other African nations achieve independence, wanted the same. Belgium wasn't happy with that and whispered in the Hutu's ears the idea of taking over the government.
The Hutu, now the government, ended up making the country independent anyways. Now, they discriminated against the Tutsi the same way they were once discriminated against.
One day, the president's airplane was shot down. The Hutu used this as an excuse to start massive hate against the Tutsi, and it escalated to a full-on genocide. ]]> 2023-05-14 22:41:15 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2590322438 RNA belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2590327790 RNA is what transforms nucleotides into amino acids, which then turns them into protein. There are two types of RNA: mRNA (messenger) and tRNA (transfer).
Everything in our body, our whole code, the book of us, is written in DNA. The mRNA translates this code into something our body understands, so it knows how to produce the amino acids needed for a certain type of protein. It takes one of the strands of DNA (DNA has two strands) and transcribes it. mRNA isn't able to transcribe the nucleotide T, so the correspondent to A is U.
tRNA is in charge of making sure the right amino acids are transfered in the process of making the protein. It takes the amino acids to the ribosome.]]> 2023-05-14 22:55:17 UTC https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2590327790 Ribosome belen_ayerza261_1 https://padlet.com/belen_ayerza261_1/vmyr7uhhx4ju5dpm/wish/2590334163 The ribosome is what reads the mRNA and translates it into amino acids.

Each gender has a reproductive cell, which are called gametes. For a woman, this is her egg. For a man, this is his sperm.
