Answer:
In liver and muscle cells, epinephrine stimulates the release of glucose from glycogen by inhibiting glycogen synthesis and stimulating glycogen breakdown.

The cell membrane is made of two layer of phospholipid called phospholipid bilayer. Phospholipid has a hydrophilic head and hydrophobic tail. The hydrophilic head stick out on the membrane, pushing polar substance that go inside. Hydrophobic substance would be easily pass through the membrane while the hydrophilic doesn't.
If the active form of this drug is polar, then the substance would be hydrophilic. The drug should pass the membrane through active transport like carrier mediated transport or endocytosis.
No information is available regarding the options of the given question. The answer will contain all the factors that might cause the loss of genetic diversity.
Answer:
Genetic diversity may be defined as the different genetic constitution is present in the population. Mutation, natural selection results in evolution that increases the genetic diversity.
The genetic diversity can be lost in the local population by the different mechanisms. The sudden loss of the genetic diversity can occur through the natural calamity. The introduction of the new allele and its selection through many generation might result in the loss of genes present already in the population. Increase in the homozygosity can also cause the loss of genetic diversity.
Answer:
1. E. A, B, and C
2. B. Smooth ER
3. D. Neither
4. B. Maintains turgor pressure in plants
Explanation:
1. Though I've never heard of "nuclear pores" in the nucleus (I've only known of them to be in the nuclear envelope), answer E is the only one that has the most obvious answer--storing genetic material. The nucleus regulates cell activities by using the stored genetic material to produce proteins.
2. There's no explanation for this as it's pretty much just memorizing the function of organelles, just remember that "lipid biosynthesis" is just basically saying "making lipids".
3. Viruses are neither eukaryotic or prokaryotic since they have no defining characteristics that eukaryotic and prokaryotic cells have. They lack a nucleus and can only replicate when inside a host cell.
4. The words "large central vacuole" should give you a big hint to the question talking about a plant cell. Turgor pressure is when the cell walls of plant cells press up against each other due to the size of the large central vacuole. This is why plants wilt when they do not have enough water, their cell walls do not press against each other so the structure is weak.
If the food chain was broken, multiple animal species would go extinct. The animals and plants in the food chain will either get out of proportion or die. This is also a major issue considering the fact that if any species falls to extinction, whatever that animal ate will completely overpopulate, considering the fact that the species is extinct. Overall, we need to food chain as a way of life, as well as for population control.
