Which mechanism(s) are responsible for introducing new alleles into a population's gene pool?
Elena-2011 [213]

Answer: The right answer is -

A) Gene flow

Explanation:

Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.

As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.

Thus, option A) is the right answer.

Answer:

BENEFITS:

The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.

A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.

The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.

LIMITATIONS:

<u>descriptive  method  of  investigation </u>

It cannot be used to correct variable or be used to determine causes and  effect  of  the  problem

<u>experimental  method  of  investigation </u>

It might create an artificial situation that do not always represent the real  life situation

<u>comparative  method  of  investigation </u>

It  is not easy to control other variables that might influence the study

Oliga [24]
Amoebae move by growing an extension of their bodies in the direction of movement and then flowing into it. This extension is called a pseudopod because when it's fully extended it resembles a limb, despite being only an extension of the amoeba's plasma membrane.
