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.

Answer:

Explanation:

the activation energy

Please Help! Don't remember going over this! What activates a convection current, starting the flow of a fluid? A. cold temperatures at the north pole B. heated liquids at the earth’s surface C. iron-rich rocks in the mantle D. temperature differences in the mantle

Answers

The correct answer is D. temperature difference in the mantle I am an Online Middle Schooler and I got it right

Final answer:

Temperature variations in the fluid start convection currents. The lower mantle in the Earth's mantle heats up due to heat from the core, which causes it to rise. The substance falls back as it cools, causing the convection current. The correct option is D.

Explanation:

Temperature differences in the fluid's area are what cause a convection current to be activated and the flow of a fluid to begin. The Earth's mantle is where this is most noticeable.

The lower mantle's temperature rises in this situation as a result of heat from the core. The density of the mantle material drops as it warms, causing it to rise.

As it rises and moves away from the heat source, however, it cools down, gets denser, and sinks back.This movement of rising and sinking due to temperature differences creates the convection current.The correct option is D.

How are DNA and chromosomes related to each other

Answers

DNA contains the instructions, genes, to make proteins that tell what genetic traits the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.
