Answer:

The correct answer will be option-B

Explanation:

A species is a group of similar organisms which interbreed with the individual of the same group of closely related individuals.

Species are reproductively isolated by various mechanisms, one of which is due to the behavior.

When the species are not able to reproduce to different species due to the differences in their behaviour in terms of mating rituals which could be due to different mating rituals or a different way of mating like observed in the grasshoppers is known as behavioral reproductive isolating mechanism.

In grasshoppers, the grasshopper's species cannot interbreed due to the differences in the mating songs as a part of the behavior.

Thus, Option-B is the correct answer.

Katen [24]

Answer:

DNA is negatively charged

Explanation:

<u>Electrophoresis:</u> In biology, the term "electrophoresis" is described as one of the different laboratory technique that is being utilized to separate protein molecules, DNA, and RNA one the basis of their electrical charge and size. Therefore, a specific amount of "electric current" is being used to move different molecules that are required to be separated through a "gel". The given gel contains pores that generally works like a "sieve" and thus allows every small molecule to proceed faster as compared to the larger molecules.

<u>DNA</u> stands for<u> "deoxyribonucleic acid"</u> is determined as a long molecule that ought to contain an individual's unique "genetic code" and generally carried information associated for making proteins in an individual's body.

<u>In the question above, the correct answer is "DNA is negatively charged".</u>
