b.neuron
c. axon terminals
d. dendrites
d. neurotransmitters
Please explain its function.

Answers

Answer 1

Answer: neurons because they make up most of the system. and they transmit the impulses and connect different parts of the system.

Answer 2

Answer: Neurons because the actually control many of the different receptor cells that make up the cns, like motor neurones and sensory neurones

Why might a scientist repeat an experiment if he/she didn't make a mistake in the first one? An experiment should be repeated toA) increase income for increased work.
B) prove how good of a scientist you are.
C) double check your results.
D) show how smart you are.

Answers

Experiments are often replicated or repeated even when no obvious mistake was visible. This is to establish how variable results are. Statistically, multiple runs are used to determine the variance or standard deviation around the average value. The best answer for this is choice C, to double check results.

Answer:

Explanation:

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.

Lisa is interested in studying the chemical processes in living organisms. In which field of biology should she pursue her studies? A. Biophysics B. Biochemistry C. Biometry

Answers

Biochemistry is the study of chemical processes of living organisms. This includes cell processes such as respiration, fermentation and many cycles such as Calvin, Krebs Cycle, or Embden-Mayerhoff Cycle. Not only the processeses, biochmemistry deals with yield of these processes in terms of metabolites and biomass concetrations.

If Lisa is interested in studying the chemical processes in living organisms, then the field of biology that she should pursue her studies in is B. biochemistry, which deals with exactly what she wants to do in her life.
