The structure of the skin is an effective barrier against bacteria. The multiple layers of epidermis, while can be invaded by foreign organisms, has a high turnover rate which means it is constantly shedding, therefore even the bacteria is shed protecting the body. Lastly, the skin's lipids maintain an acidic pH which slows and stops growth and replication of bacteria.

If a DNA molecule is found to be composed of 35% thymine, what percentage of cytosine would be expected, and why?

-Dominant- [34]

We use Chargaff's rule to get the answer. [A] + [G] = [C]+ [T]. [A] + [G] + [C] + [T] = 100% Where is A is Adenine, G is Gaunine, T is Thymine and C is Cytosine. In DNA, Adenine always pairs with Thymine, and Guanine always pairs with Cytosine. Therefore if Thymine is 35%, then Adenine will also be 35% to make 70% in total. The remaining percentage will be 100% - 70% = 30%. The 30% will be shared equally among Cytosine and Guanine, at 15% each. Therefore Cytosine will be 15%

adoni [48]

Answer:

Disruptive selection

Explanation:

According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.

From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.

According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
