Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.
Answer:
Explanation:
(1) The defective enzyme, which was suppose to break down drugs, is an oxidoreductase. Since, enzymes that break down drugs or metabolic enzymes perform there functions by oxidizing the drugs.
(2) Both codes are triplet codes for the enzyme; however the normal triplet code ought to be ATT, however there was a point mutation causing the "A" to be "C". These letters represent the bases in the DNA, <u>ATT is adenine-thymine-thymine while CTT is cytosine-thymine-thymine.</u>
(3) Further medications Henry is prescribed could include been taken with a drug/enzyme that will breakdown the actual medication.
The iris focuses light rays before they enter the posterior portion of the eye
Sensation (A) is the term for the process of sensory organs detecting external stimuli and transmitting these stimuli to the brain.
Explanation:
The nucleus contains all of the genetic material for a eukaryotic cell, but this genetic material needs to be protected. And it's protected by the nuclear membrane, which is a double membrane that encloses all the nuclear genetic material and all the other components of the nucleus
