I believe this problem has the following choices:
a. It was hard to get the fish to breed and produce
offspring for the aquaculturist to raise.
b. Because the fish were stressed in tanks, they required
much more food, reducing the profitability of rearing the fish this way.
c. The fish had to be raised in a community with several
species of fish in the same tank, and they would attack and eat each other.
d. Marine fish are more aggressive than their freshwater
relatives and they tended to fight a lot, often killing some of the other fish
in the tank.
The correct answer is:
c. The fish had to be raised in a community with several
species of fish in the same tank, and they would attack and eat each other.

In bird, females are heterogametic, produce two type of gametes. The two different sex chromosomes of a female bird has been designated to be the Z and W chromosomes. Whereas males have a pair of Z- sex chromosomes. Males are homogametic produce only one type of gametes with Z-sex chromosomes. Thus sex determination is ZW-ZZ type. In humans sex determination is XX-XY type. Males are heterogametic produce X and Y gametes and females are homogametic produce one type of gametes. Therefore, in bird sex are determined by female gametes.
Meiosis I produces 2 haploid cells and meiosis II produces four haploid cells.
Answer: Human climate drivers include heat-trapping emissions from burning coal, gas and oil in power plants and cars; cutting down and burning forests; tiny pollution particles (aerosols); black carbon pollution more commonly referred to as soot; and changes in land use that also affects Earth's albedo.
