During binary fission in a bacterial cell, a base pair is changed from adenine to cytosine due to a random mutation.
Binary fission is a type of asexual reproduction through which a bacteria divides and its body is separated into two new bodies.
If during binary fission in a bacterial cell, a base pair is changed from adenine to cytosine, it is because of a random mutation. A mutation is a genetic alteration or a change in the DNA sequence which results in the generation of a variant. Mutations in the DNA sequence which occur without any specific pattern is known as a random mutation.

Answer:
See the answer below
Explanation:
Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.
<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>

Provided that there's no diagram, most molecules have particular areas on the molecules, called the "active area" that act as a lock to a particular substrate's molecular structure, providing the key.
An enzyme's active area is only able to be "unlocked" by a certain substrate's "key".
