There are choices for this question, namely:
a. amino acids, fatty acids, and glucose
b. glycerol, protein, and glucose
c. fatty acids, amino acids, and pepsin
d. amino acids, fiber, and glycerol
e. glucose, pepsin, and cholesterol
The correct answer is "amino acids, fatty acids, and glucose". In a simpler sense, carbohydrates are broken down into glucose (a monosaccharide) that can be absorbed in the intestines. Fats in the form of triglyceride is are broken down into fatty acids and monoglycerides (not glycerol). Proteins are broken down into amino acids.
<em>
</em>
<em>Pepsin is an enzyme that aids protein digestion. Fiber is mainly composed of cellulose or plant carbohydrates that the human body cannot break down as we lack the enzyme for it. Glycerol is not released from triglycerides from digestion but instead monoglycerides (only two fatty acids from triglycerides are released).</em>

Answer:
I would say the answer is A. I'm not 100% percent but that's what I would put.
A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
Answer:
A. Migration
Explanation:
Migration is one of the evolutionary forces that change the allele frequencies of the population. Migration refers to the movement of individuals from one population to another. As the individuals move out of a population, transfer of alleles also takes place. When the immigrated individuals interbreed in a new population, they add new alleles to the gene pool of that population.
In the given example, 200 garter snakes moved out of the population resulting in changed allele frequency of the original population. Since the changed allele frequency was due to the movement of snakes, it represents migration.
The answer is: [A]: "primary consumers" .
