Answer:
The chromosomes are arranged in their respective homologous pairs. In humans, this displays 22 pairs of autosomes and 1 pair of sex chromosome.
Explanation:
Chromosomes that are similar in their size and shape and also display similar genetic traits and carry the same genetic information are paired together. These are known as homologous chromosomes. These chromosomes carry different variations of similar genes in them. In humans there are 46 chromosomes in total. These chromosomes are paired and form 23 homologous pairs. Among these 23 homologous pairs, 22 pairs are autosomes and one pair are the sex chromosomes which are either (XX or XY). The sex chromosomes determine the sex of an individual. XX chromosomes represent a female and XY chromosomes represent a male.

Answer/Explanation:
In the light independent reaction carbon dioxide, ATP, and NADPH combine to make glucose and oxygen.
Let us go over the definitions and the functions of each term:
a) Gene is a bit vague but in general it means a part of DNA that encodes one protein. Genes are the building blocks of our genomes but not the answer to this question.
b)mRNA. This is correct. The name itself means messengerRNA and its role is to copy the genetic information in the nucleus and bring it outside to be translated into protein.
c) ATP is an important molecule in our metabolism; energy is stored in this molecule and then used. It has no relationship to the mechanisms concerning DNA.
d) Thymine is one of the 4 nucleotide bases that are found in DNA, the other three being guanine, cytosine and adenine. They are essential components of a nucleotide (building blocks of DNA and RNA) but again, they do not transfer information out of the nucleus.
Answer is letter B: prophase
They are positively and negatively charged
