Answer:
B) Oxygen is needed for cell processes and carbon dioxide is a waste product
Explanation:
Cellular respiration refers to the cellular mechanism by which organisms combine molecular oxygen (O2) with organic compounds obtained from foods, it is a chemical reaction that releases 1-energy (ATP), which is used by cells to carry out its functions, 2-carbon dioxide (CO2) and 3-water (H2O). During the gas exchange, O2 is first transported from the lungs to the blood cells, which subsequently deliver nutrients and O2 to all cells of the body. Simultaneously, CO2 diffuses from cells to tissue capillaries, and then this waste product passes from the bloodstream to the lungs where is eliminated.
Answer:
morula
Explanation:
The morula is produced by a series of cleavage divisions of the early embryo, starting with the single-celled zygote. Once the embryo has divided into 16 cells, it begins to resemble a mulberry, hence the name morula (Latin, morus: mulberry).
Cytokines are frequently used by immune system cells to communicate with one another.
<h3>What impact do cytokines have on the body?</h3>
- Small proteins called cytokines play a key role in regulating the development and activity of blood and immune system cells.
- They stimulate the immune system to function once they are released.
- All blood cells as well as other cells that support the body's immunological and inflammatory responses are affected by cytokines.
<h3>What creates cytokines in the body?</h3>
- Many different cell types create cytokines, although helper T cells (Th) and macrophages are the main producers.
- By resident and migrating macrophages, mast cells, endothelial cells, and Schwann cells during normal and pathological processes, peripheral nerve tissue may create cytokines.

Answer:
Glycolysis must occur before ATP is produced, regardless of whether it is fermentation or the citric acid cycle that follows. Because hexokinase is involved in this preliminary step, if its activity were stopped, the cell could not continue to produce ATP by either pathway.

Glaciers and Ice Caps.</h2><h3>
</h3><h3>
Explanation:</h3><h3>
</h3>
Most of the fresh water on Earth is from the glacier and ice caps, it's clean water stored for many years, fresh and drinkable for us to have for a long period of time.
<h3>
Further Explanation:</h3><h3>
</h3>
Freshwater means water that is good to drink, it's not dirty, salty, or touched by any dirtiness. This includes oceans and seas, they have salty water, and have germs, bacteria, and living organisms.
That means, ice caps and glaciers are not part of the ocean, which means it's real freshwater.
Example: When you go to Antarctica, you've found a ice cap with a small lake of water, since that water isn't salty nor dirty, it's safe to drink.
Best of Luck to you!
