A life cycle is defined as the developmental stages that occur during an organism's lifetime. In general, the life cycles of plants and animals have three basic stages including a fertilized egg or seed, immature juvenile, and adult. ... The time an organism spends at each stage also varies.
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal."  Transitions of form may involve growth, asexual reproduction, or sexual reproduction.

In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.

Life cycles that include sexual reproduction involve alternating haploid  and diploid stages, i.e., a change of ploidy is involved. To return from a diploid stage to a haploid stage, meiosis must occur. In regard to changes of ploidy, there are 3 types of cycles:

haplontic life cycle — the haploid stage is multicellular and the diploid stage is a single cell, meiosis is "zygotic".
diplontic life cycle — the diploid stage is multicellular and haploid gametes are formed, meiosis is "gametic".
haplodiplontic life cycle (also referred to as diplohaplontic, diplobiontic, or dibiontic life cycle) — multicellular diploid and haploid stages occur, meiosis is "sporic".
The cycles differ in when mitosis (growth) occurs. Zygotic meiosis and gametic meiosis have one mitotic stage: mitosis occurs during the n phase in zygotic meiosis and during the 2n phase in gametic meiosis. Therefore, zygotic and gametic meiosis are collectively termed haplobiontic (single mitotic phase, not to be confused with haplontic). Sporic meiosis, on the other hand, has mitosis in two stages, both the diploid and haploid stages, termed diplobiontic (not to be confused with diplontic).

In real life, this happens too when it comes to obsidians only; there are 3 types of rocks: Igneous, Metamorphic and Sedimentary Rocks. Igneous rocks are rocks that came from the magma of a volcano and heated down into crystals. Next is the Metamorphic Rocks are rocks that change in from or also known as metamorphism, and last but not the least Sedimentary Rocks are rocks that form into small particles called sediments; Sediments are materials that can be broken down by weathering and erosion

when water and sediments are compacted and cementation, they usually became into sticky grey puddle used for building towers, statues and houses.

To summarize on how they are usually formed, Igneous are formed when Metamorphic Rocks were melted into magma after the eruption and few minutes later after the cooling it turns into Igneous rocks; Metamorphic Rocks were formed when Igneous rocks were heated and pressured into Metamorphic Rocks, same goes to the Sedimentary being heated and pressured into Metamorphic Rocks; Finally Sedimentary Rocks were formed after the cooling up of Igneous Rocks and pressuring of Metamorphic Rocks were crushed into sediments also being compacted and cemented into Sedimentary Rocks.

REPRODUCTIVE SYSTEM
Is a collection of internal and external organs in both males and females that work together for the purpose of procreating. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.

FEMALE REPRODUCTIVE SYSTEM
It is made up of the internal and external sex organs that function in reproduction of new offsprings. In the human, the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and carry foetus to full term. In puberty, females experience menstruation which have four phases.

PHASES OF MENSTRUAL CYCLE:

Menstruation
Menstruation is the elimination of the thickened lining of the uterus (endometrium) from the body through the vagina. Menstrual fluid contains blood, cells from the lining of the uterus (endometrial cells) and mucus. The average length of a period is between three days and one week.

Follicular phase
The follicular phase starts on the first day of menstruation. This triggers the hypothalamus, the pituitary gland. This hormone stimulates the ovary. And ends with ovulation.

Ovulation
Ovulation occurs in humans, when the ovarian follicles rupture and release secondary ovarian cells.

Luteal Phase
It is one stage of your menstrual cycle. It occurs after ovulation and before your period starts. During this time, the lining of the female’s uterus normally gets thicker to prepare for a possible pregnancy.

MALE REPRODUCTIVE SYSTEM
It consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles. The male reproductive system doesn’t have a cycle like the female reproductive system.

FUNCTIONS OF MALE REPRODUCTIVE SYSTEM:

·        To produce, maintain, and transport sperm cell and protective fluid.

·        To discharge sperm within the female reproductive tract during sex.

·        To produce and secrete male sex hormones responsible for maintaining the male reproductive system.

Orbit, is a term used to describe the repeating paths of objects in space that spins of goes around another object. The objects that are in an orbit are called satellite. Examples of these are all the planets in the solar system that orbits around the sun, and the moon that orbits around the Earth. All of these orbit to the shape of an ellipse.
-The orbit of Mercury around the Sun is about 88 days with an average orbital speed of 47.362 km/s.
-The orbit of Venus around the Sun is about 225 days with an average orbital speed of 35.02 km/s.
-The orbit of Earth around the Sun is about 365 days with an average orbital speed of 29.78 km/s or 107,200 km/h.
-The orbit of Mars around the Sun is about 687 days with an average orbital speed of 24.007 km/s.
-The orbit of Jupiter around the sun is about 12 years with an average orbital speed of 13.07 km/s.
-The orbit of Saturn around the Sun is about 29 years with an average orbital speed of 9.68 km/s.
-The orbit of Uranus around the Sun is about 84 years with an average orbital speed of 6.80 km/s.
-The orbit of Neptune around the Sun is about 165 years with an average orbital speed of 5.43 km/s.
-The orbit of Pluto (reclassified as a planet) around the Sun is about 248 years with an average orbital speed of 4.67 km/s.

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water cycle or the hydrologic cycle is the water from oceans, lakes, swamps, rivers, plants, and even you that can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as snow or rain.

There are many processes involved in the water cycle, but the most important are evaporation, transpiration, condensation, precipitation, and runoff.

-First is evaporation. Evaporation is the process by which water changes from a liquid to a gas or vapor.
-Second is transpiration.  Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
-Third is condensation.  Condensation is the process by which water vapor in the air is changed into liquid water.
-Fourth is precipitation.  Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.
-And the last process is runoff. Surface runoff is water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle.

That's how the water cycles.

Food chain shows how living organisms get their food. Some animals eat plants or some animals eat their own kind or other species. Most living organisms is plants. All food chains start with the energy from the sun. The energy from the sun being captured by the plants. The food chain always starts with the plant and it ends with the animal or sometimes it can be a human but it still depends on the food chain process.

The plants are called the producers. Animals cant produce their own so they eat animals or hunt for other animals. They are called consumers. Theres three kinds of consumers. Omnivers, Carnivores and Herbivores.

What are the difference you may ask. Ill explain it to you.

Herbivores are animals that only eat plants. Omnivores are aminals that eat both plants and animals. And Carnivores are animals that only eat animals or meat. Then when the animal doesn’t finish their meal theres something that feeds on it. They are called decomposers (bacteria, fungi, and even some worms). They speed up the decaying process that releases mineral salts back into the food chain so the plants can absorb the nutrients from the body of the decaying animal.

For example the plant is the producer and the plant was consumed by a grasshopper and the grasshopper was consumed by a bird and then the bird was consumed by snake and the snake was consumed by a eagle. If the eagle dies the bacteria will speed up the process of decaying and the plants will able to redeem the energy that the other comsumers took.

The grasshopper is called the first consumer. The bird is the second consumer. The snake is the third consumer and the eagle is the fourth consumer. The bacteria is the decomposers. And the food chain process will repeat again. That’s how living organisms survive and get their food to survive and not starve to death.

PHOTOSYNTHESIS

Photosynthesis is a process used by plants and other organism that convert light energy into chemical energy that can later be released to fuel other organism's activity. First, photosynthesis takes in carbon dioxide produced by all breathing organism and it introduces oxygen into the atmosphere. It is a process used by plants, algae and certain bacteria to harness energy from sunlight and convert it into chemical energy. Photosynthesis has two types of photosynthetic process: the oxygenic photosynthesis and anoxygenic photosynthesis. Their general principles are very similar, but, the oxygenic photosynthesis is the most common one and it can be seen in plangs, algae and cyanobacteria. While anoxygenic photosynthesis is where light energy is captured and converted to ATP (Adenosine Triphosphate.) Anoxygenic photosynthesis exists and can be seen in multiple groups of bacteria.

Cardiovascular system or what we call Circulatory system is one of the systems that has many functions. It fights diseases by using blood cells, it carries digested food from the small intestine to all areas in the body which need it, it distributes heat, it aids in the disposal of all wastes from the body, it helps us with our blood circulation and lastly, what we will be explaining is the carrying of the oxygen from the lungs to the rest of the body. This has an organ called heart that is the center of the system.

How does the carrying of the oxygen from the lungs to the rest of the body is done?

It starts when the heart relaxes between two heartbeats. Starting to the oxygen poor blood from the body, it will enter to the superior and inferior vena cava. After that, it flows through the right atrium. Through the right atrium the blood flows to the right ventricle.The right ventricle pumps blood through the shorter pulmonary circuit then to the lungs. In the lungs the blood gets oxygen and releases waste gases. It will be now a newly oxygen rich blood, it will enter again to the heart through left atrium. After the left atrium passing to the bicuspid valve will now flow into the left ventricle. The left ventricle’s walls are thicker and stronger. The left ventricle pumps blood through the longer systemic circuit and pumps the oxygen rich blood to the all parts of the body through the aorta. To the body it will go back again to the superior and inferior vena cava.

Through the blood vessels, the oxygen poor and rich blood will be able to flow into the body. The arteries have a thick muscular wall, have no valves, have a pulse and deep under the skin, while the veins have thin walls, have valves to stop the back flow of the blood, have no pulse and near surface on the skin. The Arteries and Veins have many differences the arteries is carryng the blood away from the heart while the Veins carry blood to the heart.

To the development of the body from the womb of the mother and to the moment of death the heart pumps. All day the heart pumps blood through the body. We only have a one heart so it is important to take care of it.

The digestive system is made up of the gastrointestinal tract. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system. There are also major parts of the digestive system, salivary glands, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and the accessory digestive organs: liver, gallbladder, pancreas. Parts of your nervous and circulatory  systems also help. Working together, nerves, hormones, bacteria, blood, and the organs of your digestive system digest the foods and liquids you eat or drink each day.

Weather Formation

Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the lowest level of the atmosphere, the troposphere, just below the stratosphere.

The suns radiation heats up the surface of the earth then the soil releases the radiation from the sun which warms the air. Once the ground is heated enough the warm air rises above the ground which called is conduction and when the air rises, it will slowly become more cold and the air parcels will condense due to convection once it exceeds the dew point the clouds form.
Then when the cloud is heavy enough due to multiple air parcels that exceeded the due point it will pour water that will be later called ‘rain’.
