Answer:

b. determine the evolutionary relationships among species

Explanation:

Biologists through the analysis of characters obtained from molecular, morphological, embryological, physiological and behavioral analyzes look for the relationship between species and their origin.Through these coincidences phylogenetic trees are made.

kow [346]

Answer:

Cell Division. Read explanation

Explanation:

It wouldn't be any of the sex cells so that would take out gene activity and offpsring. The only thing that changes the somatic (body) cells would be the slowing of cell division which I would assume is the correct answer.

According to scientists, ocean waves could be a source of energy. Devices are being designed to capture the energy from waves an
Vilka [71]

If we say something is beneficial, it must be positive and really mean to give advantage to one thing or another. Wave energy is a renewable energy since it can be used repeatedly over time without any problem on supply. Hence the greatest benefit it can give would be:

 

decreased use of nonrenewable resources

Would we have the Same countries If Pangea existed? And would we look the same?explain please
Natalija [7]
I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.

The relative location of four genes on a chromosome can be mapped from the following data on crossover frequencies Genes B and D
kykrilka [37]

Answer:

3. CABD

Explanation:

The gene mapping refers to providing position to the genes on the chromosomes.  The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.

The gene mapping refers to providing position to the genes on the chromosomes.

In the given question to construct gene map:

1. Look for the highest recombination frequency that is 50% between the C and D.

2. Now look for second-highest value and place the gene accordingly.

3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.

Thus, Option-3 is correct.
