professor190 [17]

Answer:

B. Water evaporates more quickly when temperatures are high

Explanation:

Constructing an hypothesis is KEY to any experimental setup. It is the first thing to do in accordance to the scientific method. A hypothesis is simply a predicted statement that aims at proferring solution that is subject to testing via experimentation.

According to this question, Mae observed that the birdbath in her backyard loses water more quickly during hot summer days than during the cooler days of the spring. A suitable hypothetical statement for this observation would be: "Water evaporates more quickly when temperatures are high".

N.B: Hypotheses are not questions

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.

As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

<h3>What is Genetic material?</h3>

Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.

In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.

These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.

Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
