Answer:
- <u>Cell has a limited supply of NAD+</u>
Explanation:
Cellular respiration occurs in the cytoplasm, where glucose is broken down for energy processing. Energy is produced by aerobic respiration in the presence of oxygen, whereas anaerobic respiration can be carried out in an oxygen-deprived environment.
Fermentation is one kind of anaerobic respiration- here, the cells use glucose to generate a Net 2 molecules of ATP from the 6carbon sugar. Glucose is first converted to pyruvate, which is oxidized in a complex process. While 4 ATP are produced in fermentation, 2ATP are used in regenerating NAD+ from NADH2.
Two types of fermentation include lactic acid fermentation and alcoholic fermentation. These occur in single-celled, and multicellular microbes.
Answer:
the conclusive evidence about CFCs (chlorofluorocarbons) and the ozone layer of the earth.
Explanation:
Susan Solomon, Web of Science article reveals the conclusive evidence that CFCs (chlorofluorocarbons) could be destroying the protective layer of ozone in the earth’s upper atmosphere. CFCs are compounds that have the potential to destroy the protective layer of ozone (an oxygen compound) in the earth’s upper atmosphere.
Answer:
Both animal mitosis and plant mitosis produce two daughter cells with the same amount of genetic material.
Answer: Option D
Explanation:
The bacteria can undergo cell differentiation in response to the environmental conditions.
The oxidative stress, antibiotic exposure, stress conditions are some of the external conditions due to which the bacterial cell can respond in the cell differentiation.
The bacterial species can divide based in the conditions in which they are put. So it is true that under stress conditions the bacterial cell can undergo cell differentiation.
