I think it's the correct answer is D, thought it could be C as well
Answer:
The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.
Explanation:
The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.
The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.
Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:
<em>C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂</em>
This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.
For the other options it is important to mention that:
- <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place.
</em>
- <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
Answer:
Mitosis is a division of a eukaryotic cell in which the chromosomes are evenly distributed among the daughter cells.
In multicellular organisms, both sexual and asexual reproduction is followed by cell division, which ensures the growth and development of the organism. In addition, cell division is necessary to replace dead cells and repair injuries. New cells are constantly being added and old ones are being destroyed. About a hundred thousand more cells are created every second, and of course the same number dies. The new cells start with the division of the source cell. The cells formed in this way are called daughter cells. Stem cells can gradually divide into all the different cells in the body through mitosis.
Most of the body's cells are constantly renewed by mitosis, but there are also so-called irreplaceable cells that are formed only once in a lifetime for the life of the organism and do not regenerate by mitosis.
I believe they cannot start with big trees and bushes because the there is not enough nutrients in the soil, so instead pioneer species pave the way for primary succession.
