If genetic drift is occurring you will be able to predict which allele will become more prevalent.

Biology
1 answer:
Blizzard [7]3 years ago
7 0

Answer:

b. False

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. As happens at random, it is impossible to predict which allele will be prevalent in a population suffering from genetic drift.

Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent.

Thus limiting the genetic content of a particular group, restricted to the prevailing individuals. It is up to them, integration into another population, if an adaptation is maintained, or over time, from geographic and later reproductive isolation, constitution of a new species (principle of the founding species).

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals.

During evolution, a hypothesis concerning the decimation of dinosaurs, which occurred around 66 million years ago, establishes not only the end of these animals, but of various life forms (including plants), due to a huge asteroid that would have reached planet, raising a dense cloud of dust resulting from the collision, compromising photosynthetic processes (dependent on solar energy), as well as the respiration and nutrition of organisms.

digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most like
horrorfan [7]

The most likely explanation to the statement that digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach is C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

The pH of the mouth is near neutral whereas the pH of the stomach is acidic due to the hydrochloric acid present in the stomach.

All enzymes, including the digestive enzymes, require a certain pH at which they are better able to function. If the pH is altered, then the shape of the enzyme changes, which affects the shape of the active site of the enzyme. As a result, the substrate is no longer able to fit in the active site.

Hence, those digestive enzymes that function in the mouth will not function in the stomach due to the altered pH.

Although a part of your question is missing, you might be referring to this question:

Digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most likely explanation?

A. Enzymes have only one active site. Once a substrate binds, that enzyme is no longer usable.

B. Enzymes are changed in a reaction. Enzymes made in the mouth are used up by the time they get to the stomach.

C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

D. There are no substrate molecules left when the enzyme reaches the stomach, so the enzyme stops working.

mina [271]

Answer:

Dependent Variable

Explanation:

An experiment has dependent and independent variables. The dependent variable is the one that is being studied and responds to the independent variable.

In the given experiment, the effect of a new drug is being studied on blood pressure. Here, the blood pressure (systolic and diastolic blood pressure) is supposed to change in response to drug treatment.

So, blood pressure is a "dependent variable" while the drug treatment is "independent variable".
