A human cell that contains 22 autosomes and a Y chromosome must be(A) a zygote.
(B) a somatic cell of a male.
(C) a somatic cell of a female.
(D) a sperm cell.
(E) an egg cell

Answers

Well it can't be C because the DNA of female cells do not have any Y sex chromosomes. It also can't be E because of that same reason (the egg is made by the female, so it can only contain her genes).It can't be A because zygotes are diploid (because the egg and sperm, both haploid with 23 chromosomes, fuse together to double the amount of chromosomes), so a zygote would have to have 46 chromosomes, not 23 with 22 being autosomal and 1 being allosomal/sexual like the question states. And finally, it can't be B because somatic cells are also diploid and have 46 chromosomes. Another clue it can't be B is that the question states it has only a Y chromosome, which means the cell can't be diploid because a diploid cell has two allosomal chromosomes, either XX or XY.

Final answer:

A human cell with 22 autosomes and a Y chromosome is a male sperm cell. Sperm and egg cells contain 23 chromosomes, including one sex chromosome, while other cells typically have 46 chromosomes.

Explanation:

A human cell that contains 22 autosomes and a Y chromosome is (D) a sperm cell. Human cells are normally diploid, meaning they contain 46 chromosomes: 22 pairs of autosomes and a pair of sex chromosomes. Somatic cells (both male and female) have a total of 46 chromosomes, while a zygote, the cell formed after the fusion of an egg and a sperm, is also diploid. However, sperm and egg cells, which are haploid, carry only 23 chromosomes: 22 autosomes and either an X (in the case of an egg cell or a male sperm cell) or a Y (in the case of a male sperm cell) chromosome.

What would happen in an ecosystem without primary consumers?The populations of producers would increase.

The populations of omnivores would increase.

The populations of carnivores would increase.

The populations of decomposers would decrease.

Answers

I think the correct answer among the choices listed above is the first option. In an ecosystem without primary consumers, the populations of producers would increase. This is because nothing will eat the the producers or the plants. The plants will only grow and increase.

Answer:

The Population of Producers would increase

Answers

Answer: increase understanding not only of the construction of individual genes but also of their relation to each other and to the entire chromosomal structure.

Explanation: The Human Genome Project is using primarily three levels of maps, each of which helps to increase understanding not only of the construction of individual genes but also of their relation to each other and to the entire chromosomal structure.
