Which cells in your body goes through mitosis the most and least?

Answers

Answer:

Somatic cells in your body goes through mitosis the most. And

Gamete cells in your body goes through mitosis the least.

Mitosis occur most in somatic cell  and least occur in germ cell of the body.

What is mitosis?

Mitosis is process occur both in unicellular and multicellular organisms, the division of the cell where the number of chromosomes remains the same, except in the case of germ cells where the number of chromosomes become half.

In this stage of cell cycle the nucleus of a cell is divided into two nuclei having equal amount of genetic material and produce both the daughter nuclei.

It is succeeded by cytoplasmic division after the separation of the nucleus. It is important for the growth of the cells and the replacement of worn-out cells.

In every cell division, production of two daughter cells are from the parent cell; It is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.

Locate Chicago and New York on a US map. Describe their locations in the United States. Do you think their location played a role in the amount of snowfall they got throughout the year? Why or why not?

Answers

Answer:

Explanation:

In the attached picture below, you can see New York marked in Red, and Chicago is marked in a Blue circle. Both locations are extremely cold during the winter months due to being so close to the north pole. Aside from being close to the north pole, both of these locations are located on large bodies of water which increases wind and therefore lowers the temperature. Between both of these Chicago would get more amount of snowfall per year due to being closer to the North Pole than New York.

In the sample of water, there are 100 atoms of oxygen and 200 atoms of hydrogen. How will the mass of oxygen compare to the mass of hydrogen?

Answers

Answer:

The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1. If we have 2 atoms of each element, the ratio of their masses is approximately 32:2, which reduces to 16:1—the same ratio.

The mass of oxygen compared to the mass of hydrogen is approximately 16:1.

What is a chemical reaction?

There are several types of chemical reactions depending on the reaction mechanisms: combination, single-displacement, double-displacement, combustion, decomposition, combustion and redox reactions.

Thus, 16:1 is the answer.

When skin cells are damaged by ultraviolet radiation from the sun, they are replaced by new ones. Explain how this fact provides evidence that supports one or more parts of cell theory?

Answers

Answer:

See the answer below

Explanation:

When skin cells are damaged by ultraviolet radiation from the sun, the cells present in the tissue of the skin are triggered to start dividing by mitosis in order to produce new cells that replace the damaged cells. Thus, new cells are produced from the old cell.

This phenomenon agrees with the part of the cell theory that says that cells can only arise from preexisting cells. More specifically, cells are only able to arise from preexisting cells through the process of cell division.

The damaged skin cells are replaced by the new cells, which are formed of the cells that preexists, that is, present already, this supports one of the cell theory that all cells originate from the preexisting cells.  

• The three prime points of the cell theory are that all the living things are formed of cells. The cells are the fundamental units of life, and all the cells comes from the preexisting cells by the process of cell division.  

• The cells are always formed from the cells already present.  

• In case, if the skin cells gets damaged by UV rays from the Sun, they get replaced by the help of cells, which are already present underneath the dead cells.  

• These new cells do not come from thin air, the cells underneath get triggered and by the process of mitosis give rise to novel cells.  

Thus, the replacement of the damaged skin cells by the new cells proves theory that all the cells comes from the preexisting cells by the process of cell division.

Answer of the following questions is given below.

Radiant energy is called EMR or electromagnetic energy. This is energy that is transmitted without the movement of mass. This energy is found in waves and is also called light energy. The light is made by the individual particles called protons. Hence the option B is correct. Aerobic respiration is the form of respiration that requires O² in order to generate energy. The full oxidation of nutrients. It produces large amounts of energy. Hence the option D is correct. The anaerobic oxidation glucose is broken down without the presence of oxygen. Instead of carbon dioxide water, lactic acid is made that leads to muscular cramps. Hence the option D is correct. A fungus is an example of a decomposer as the fungus derives nutrients b decomposing the matter. Hence the option C is correct. Producers play an important part in the recycling of matter as they convert the light energy into organic molecules. Hence the option A is correct.
