A scientist is studying a biome that experiences large seasonal fluctuations in both temperature and precipitation patterns.
balu736 [363]

Answer:

Generalists would be most abundant, because the resources available would be constantly changing.

Explanation:

A generalist species is a species that can live and survive in different types of environments, and also have different range of diets it can feed on. Ominivores such as raccoon is an example of a generalist species which has varied diets and can survive in different environmental conditions, enabling it to maintain its population from season to season.

Organisms that would inhabit a biome that experiences large seasonal fluctuations in both temperature and precipitation patterns is best characterized by the abundance of generalist species, be because the resources available would be constantly changing.

A nerve cell and a liver cell in the same organism contain different combinations of proteins. Which of these statements best ex
Yuri [45]

Question options found from another source:

a. The different cells in an organism contain different genes

b. Each cell in an organism transcribes only the genes that the cell needs to perform its functions

c. Each cell in the organism produces the same proteins, but the ones that aren't needed are immediately digested

d. The different cells in an organism all transcribe the same genes, but their ribosomes make different proteins from them

Answer:

b. Each cell in an organism transcribes only the genes that the cell needs to perform its functions

Explanation:

Every cell in an organism contains exactly the same DNA, but it is how that DNA is put to use that affects the identity of the cell.

In a nerve cell and a liver cell the DNA is the same, but the expression of different genes, and therefore the combination of proteins present, will be hugely different.

This is because different combinations of genes are transcribed in different cell types that make one cell function as a liver cell and one as a nerve cell. These genes are cell-type specific. For example, a liver cell might express enzymes important for the breakdown of toxins, whereas a nerve cell might produce proteins important for signalling.
