The correct answer is A. There is no need to find a mate.

The definition of asexual reproduction is a type of reproduction that a single organism can reproduce by itself. Therefore, the organism doesn't need to find a mate to reproduce.
The opposite of asexual reproduction would be sexual reproduction which requires a mate to reproduce.

The answer B. is incorrect. In sexual reproduction, a process called meiosis exchanges genetic info between two organisms of different gender, meaning that there is an increased "number" of diversity.

The answer C. is incorrect. In asexual reproduction, there are multiple forms of reproduction but the most common process is called binary fission in which the organism just splits itself into 2. In asexual reproduction, there isn't a process called meiosis, which involve the fusion of gametes.

The answer D. is incorrect. Generally, asexual reproduction requires less energy than sexual reproduction. I have no idea if our world has the technology to measure the amount of energy spent reproducing in an organism, however; the process of meiosis is a bit complex compared to binary fission or multiple fission. We can infer that asexual reproduction consumes less energy than sexual reproduction.

Answer from: Quest

you are certainly talking about this picture:

a: is the label of the white square, it is showing the replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes the dna with the dna template and increases the processivity of the enzyme. ==> stops polymerase from falling off the template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built in the opposite sense of the helicase, so dna will be built in fragments ==> built fragments from 5' to 3 joins

and finally f: is the enzyme that builds the new dna strand (dna polymerase) ==> adds nucleotides to make a new dna helix.
