kaheart [24]

Answer:

C) The two populations will evolve into separate species.

Explanation:

In the given question, the population of animals has been split into two different populations due to a natural barrier present between them.

When we will observe these species after a very long time, the species will not be able to reproduce with each other and will be reproductively isolated.  This reproductive isolation will lead to the formation of new species but belonging to the same genus.

Thus, Option-C is correct.

A single strand of DNA helix has the code CGCTAA. Which would be the complementary code on the other strand of the helix?
Yakvenalex [24]

The correct answer is option 4, that is, GCGATT.  

Complementary strand refers to either of the two chains, which forms a double helix of DNA, with corresponding positions on the two chains comprising of a pair of complementary bases. It is a section of one nucleic acid, which is bonded to another by an alignment of base pairs.  

In nature, complementarity refers to the base principle of DNA transcription and replication as it is a characteristic shared between the two RNA or DNA sequences, such that when they are arranged antiparallel to each other, the nucleotide bases at each position in the sequences will be complementary.

A swimmer sprints a short distance for a competition. The swimmer is not able to take in enough oxygen to make the ATP needed fo
Reptile [31]

When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.

Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
