Answer:
Aquaculture is a type of farming performed in water bodies like lakes, ponds, oceans to breed aquatic plants and animals like fish, mollusks, crustaceans, algae, etc. Aquafarming is done to increase food production and to earn money from it.
Apart from the advantages aqua farming has several disadvantages. One of the main disadvantages is the transfer of parasites or diseases from one fish to another is easy in aquaculture because fishes live in dense populations in aquaculture. So fish in aquaculture are highly vulnerable to diseases.
Excess fecal matter produced by farmed fish can pollute the ecosystem which has an adverse effect on the other species live in that ecosystem.
Answer:
A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.
Explanation:
During sexual reproduction, meiosis produces the sex cells that combine to make new children.
Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.
Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.

Because of the severe impact that we impose on the land, air, and water, conservation has
become increasingly important.
Conservation is using natural resources wisely and not contributing to pollution of the land, air or water. Human activities can benefit the environment and help preserve resources.
Conservation can include small-scale clean-up projects along roadways or building fences to prevent dune erosion to large-scale beach renourishment. Planting trees is another way to support conservation as trees are too often removed without being replanted.
The phrase “Reduce, Reuse, and Recycle” has been a catch phrase of the late 20th and early 21st centuries.
