In <u>asexual </u>reproduction, genetically identical offspring are produced, while in <u>sexual </u>reproduction, offspring are genetically different from each other.
Sexual reproduction is a sort of reproduction that involves a complex existence cycle wherein a gamete (inclusive of a sperm or egg mobile) with an unmarried set of chromosomes (haploid) combines with another to provide a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).
Sexual reproduction is the maximum common existence cycle in multicellular eukaryotes, which includes animals, fungi, and plants.
Asexual reproduction is a sort of reproduction that doesn't involve the fusion of gametes or change in the number of chromosomes. The offspring that get up by asexual reproduction from both unicellular and multicellular organisms inherit the whole set of genes in their single parent. Asexual reproduction is the number one shape of reproduction for single-celled organisms including archaea and bacteria.

<span>The correct option is A. Founder's effect is the reduced genetic variability that occur as a result of population production from a small number of colonizing parents. The founder's effects is one of the ways by which nature can randomly produce new species from existing population.</span>
Growth factors are hormones, proteins, or steroid molecules that regulate many cellular functions. They can stimulate the cell division by giving the signal to the cell to progress in the cell cycle.
<u>Explanation</u>:
Growth factors are naturally produced within the body and travels through the body to bind to their receptors present on their target cells. These growth factors are capable of signalling the cell to divide, proliferate, or heel. Their main aim is to signal or tell other cell when to do and what to do. Due to the binding with the receptors the growth factors activates specific genes.
Answer:
Answer is true.
Explanation:
That calories that remain when the amount of nutrients required by the body are met is the discretionary calories.
These calories are good and essential because they are useful to the body when it is in need of calories, usually after exercise or rigorous work.
They are derived from foods that are rich in fat, such as cheese, milk, yoghurt etc.
