The image represents the mitosis process and it is important because:

A. produces gametes with half genetic information than parent cell.
B. allows processes as growing and repair tissues in the body.
C. does not produce cells with the same genetic information than parent cell.
D. always produce somatic cells with the same characteristics, it does not matter the organ in the body.

Answers

Answer:

B. allows processes as growing and repair tissues in the body.

Explanation:

Mitosis is a process where a single cell divides into two identical daughter cells. During mitosis one cell divides once to form two identical cells and the dividing cell's chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.

The major purpose of mitosis is for growth and to replace worn out cells. It also plays an important part in the development of embryos.

Mitosis is divided into five stages:

1. Interphase- during interphase, the DNA in the cell is copied resulting in two identical sets of chromosomes. Microtubules also extend from the centrosomes outside the nucleus

2. Prophase- during this phase, the sister chromatids in each chromosome pair up, the nuclear membrane dissolves and the mitotic spindle consisting of microtubules and other proteins extend across the cell between the centrioles which move to opposite ends of the cell.

3. Metaphase- the chromosomes line up at the centre of the cell and the mitotix spindle attaches to eachmof the sister c hromatids.

4. Anaphase- the sister chtomatids are pulled apart to each end of the cell by the mitotic spindle.

5. Telophase- at each pole, a full set of chromosomes gather together, a membrane encloses each chromosome, the cell pinches at the middle and then divides into two. This is known as cytokinesis.

7. Based on what you know about Carbon Dioxide (look at the definitions section) and the Description of the Landscapes, how did the amount of Carbon Dioxide in the atmosphere increase over time? 8. Carbon Dioxide and Water vapor are greenhouse gases. How do greenhouse gases act like the glass in greenhouses?​

Answers

Answer: Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. Global atmospheric carbon dioxide concentrations (CO2) in parts per million (ppm) for the past 800,000 years. ... Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. The large numbers of land animals raised to feed the Earth's growing population results in increased carbon dioxide levels in the atmosphere due to farming practices and respiration and methane production. This is another example of how human activity indirectly affects biogeochemical cycles in a significant way.  8. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse.

In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles

Answers

Answer:

The correct answer is - increase: constriction of the arterioles.

Explanation:

When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.

It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

What is the end product of photosynthesis ?

Glucose is the end product of photosynthesis which is the ultimate source of energy for plants.

Photosynthesis usually takes place in 4 steps where the first step is the absorption of light where the light from sun is absorbed by stomata and the various reactions that take place in the light are called as the light reactions.

Transfer of light helps to electrons to excite and the excitation of electrons helps to make new products various phosophorylation reactions that is the production of ATP is taking place or the lysis of the product is taking place as well.
