B. because a mass extinction is caused by several causes to force a group of organisms to die.
In order to use amino acids as fuels, amino acid metabolism must occur. This process results in the formation of 2-oxo-acids.
<h3>
What is amino acid metabolism? </h3>
The excess proteins/amino acids in the body are to be broken down or catabolized as there is no mechanism for the storage of amino acids in the human body. Different amino acids have different mechanisms of catabolism.
Based on their catabolism process, amino acids are categorized into two types.
1. Glucogenic amino acids - The amino acids which can be converted into glucose, pyruvate, and intermediates of the TCA cycle are called Glucogenic amino acids. These intermediates are converted to 2-oxo-acids.
2. Ketogenic amino acids - These are either converted to fat, Acetyl CoA, or AcetoacetylCoA. These condense with 2-oxo-acids and the net gain is zero.
Therefore, amino acid metabolism results in the formation of 2-oxo-acids.

Answer:
a. This is actually a case of frequency-dependent selection. With too many cheaters in a population, the fruiting body's stalk is not built well, and all individuals have lower fitness.
Explanation:
Frequency dependent selection is a process in evolution whereby the
a gene, genotype or phenotype varies depend on the percentage of that gene, genotype or phenotype that is present in the population.
There are two types of frequency dependent selection:
a. Positive frequency dependent selection.
b. Negative frequency dependent selection.
Your answer is D lives in the same region as others closely related species. Because it wouldn't be C cause that's not isolation it would be B cause there not plants and its not A because it is reproductive but its not isolation.
The Great Plains have a continental climate. Much of the plains experience cold winters and warm summers, with low precipitation and humidity, much wind, and sudden changes in temperature. More rainfall occurs in summer than in winter, except in some of the northwestern parts of the Great Plains.
Hopes this helps!
