A population in which the frequency of alleles remains the same over generations is said to be in genetic equilibrium. Describe
DochEvi [55]

Answer:

Natural selection disrupts the genetic equilibrium by favoring the genes for the traits that impart survival advantage to individuals.

Explanation:

Natural selection refers to the unequal survival rate of individuals of a population due to the presence of some beneficial adaptive genetic trait. These individuals are able to survive more and leave more progeny. Over generations, the population has increased number of these individuals leading to evolution of a population with different allele frequencies.  

For example, the frequency of gene for antibiotic resistance in the bacterial population was increased once humans started using antibiotics to control the bacterial population. This led to the evolution of the bacterial population with antibiotic resistance.

What did Charles Darwin discover as a result of his experiments with breeding pigeons?
Veronika [31]
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.

Identify the false statements regarding ketone bodies.
anygoal [31]

Answer:

Option D is false

Option E is false since it is incomplete

Option C is false

Explanation:

Well, regarding option D it is considered false because the functional groups would be:

Acetone (which is not used as an energy source, is exhaled or excreted as waste), Betahydroxybutyrate and acetoacetate (if not oxidized to be used as an energy source).

In statement C it is false, because the formation of ketone bodies increases with the presence of acetylcoA, but acetone is one of those that will always be witnessed in a lower percentage, since it is excreted by the body as waste, both either by the airways in the exhalation (characteristic ketone breath) and in the urine (cetouria)

And as for the E option, I consider it false because the ketone groups are formed in the liver and kidney.

Greater proportion in hepatic mitochondria and to a lesser extent in the kidney
