1. Mitosis and its Phases.

This was a very interesting topic. lets get into it. Mitosis means exact coping of cells. We are going to start with Interphase, in this phase is where the cell starts to grow thats called the G1 phase. then comes the s Phase that's where the coping of the dna happens. After the s phase is the G2 stage thats where the cell continue to get larger and larger.

Now lets get into Mitosis: the first step of Mitosis is the Prophase, thats where the Chromatins has gotten together to become Chromosomes and in this phase the nucleolus Dissapears. The second Phase is the Prometaphase, what happens here the Nuclear envelopes breaks apart, the Chromosomes form two Kinetacores at the center mere and the micro tubules attaches to the Chromosomes. the Third Phase is the metaphase and that when the Chromosomes line up in the middle. Forth is the Anaphase is when the Chromosomes pull apart going on each side. In Telephase the new nuclear envolope forms, Chromosomes unfold back into Chomatin the nucleoli reapear then the cell begins to get bigger and bigger.

Cytokinesis is when the cell divides in half. The cell well get into the whole process again G1 phase, the s phase, the G2 phase.

2. The importance of Water in the body and properties of water

The molecule of water is H2O. Water is a chemical substance which has two hydrogen covenant bonds and a single oxygen (Eisenberg & Kauzmann, 2006). There are three types of known water in the world: gas, ice, and liquid. Because the properties of water contain hydrogen, it is mostly liquid. Water is a polar inorganic compound that is tasteless and odorless liquid (Eisenberg & Kauzmann, 2006). Water is considered a universal solvent, because most of the substances in the world can be dissolved by it (Eisenberg & Kauzmann, 2006). Water is also a symbol of life on Earth.

Water is essential for life. In fact, most of the human body is made of liquid. Without water, many organisms, including humans, could not survive. It is needed for a variety of purposes. These include nurturing cell life, chemical and metabolic reactions, transportation of nutrients, elimination of wastes, and body temperature regulation (Main functions, 2018).

Water plays an important role in the mechanism of the cell. When humans consume water, water goes into the cells. Cells cannot live without water. Without the help of water, cells cannot get necessary nutrition. Humans consume different types of food to get energy for daily activates. Nutrition from the food is dissolved with water and enter the cells (Main functions, 2018). Cells can use this nutrition for functioning.

After eating food, the food goes to the stomach and through the digestive system. Water plays a vital role Food dissolves inside the stomach and then travels through the intestines. Nutrients are absorbed through the mucus membrane into the bloodstream (Main functions, 2018). Blood goes to different places in the body, and different organs in the body get necessary nutrition for functioning. The important and vital nutrition are minerals, vitamins, protein components, lipids and carbohydrates (Main functions, 2018). When the body gets all of the needed nutrition, the waste goes out from the body in the form of urine and feces (Main functions, 2018).

In conclusion, water is essential for life. It is used for a variety of purposes for healthy living. Humans cannot live without. I prefer purified water. It helps me stay hydrated and contributes to a clean life style. The next time you drink a glass, think about the importance to life it adds.
