Answer:
D) a genetic bottleneck
Explanation:
Genetic bottleneck refers to the sudden reduction in the population size due to some adverse climatic factors such as natural calamities. It changes the allele frequencies since the survivor population mostly have different allele frequencies than the original population.
In the given example, an earthquake kills 98% of the squirrels. The survivor population exhibits different allele frequencies for the gene responsible for the thickness of stripes. Therefore, it represents a genetic bottleneck.
Answer:
Option A
Explanation:
The rate and amount of decomposition of alcohol depends on the amount of body fat in an individual. The activity of enzyme alcohol dehydrogenase that breaks down alcohol is affected by concentration of body fat and water.
The higher the body fat and the lower is the body water and fluid, the higher is the activity of enzyme alcohol dehydrogenase.
Thus, the higher activity of enzyme alcohol dehydrogenase ensures higher rate of breakdown of alcohol due to which level of alcohol concentration in blood of an individual reduces.
Hence, option A is correct
Which of the variables affects the mass of the rock (samples)?
OR
which of the variables causes the breakdown of the rocks (samples)?
The given scenario illustrates An emergent property.
<u>Explanation:</u>
A property that explains about the functioning of any system as a whole is an emergent property. The units of that individual system will not work to give the functionality of the entire system. Fallacy of division occurs when there is a failure in the realization of this emergent property.
For instance let us take an ant colony. Ant as a single organism will not be able to attain certain works. While when they join to form a colony they together can accomplish complex and tedious tasks. Hence, in human body also cells of heart acts as an example of an emergent property as they together can accomplish the function.
