Answer:
D
Explanation:
D. The second cell would not be able to produce as much food because it could not capture sunlight.
Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons
Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:
- Astrocytes: they maintain the blood brain barrier.
- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.
- satellite cells: These cells help regulate the external chemical environment of neurones.
- Microglia: they clean up cellular debris through phagocytosis.
- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system
The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP.
Explanation:
Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.
After it is converted into trioses dihydroxyacetone phosphate as well as glyceraldehyde through aldolase. With glucose metabolism Fructose get synergistic effect
Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
