Explanation:
<u>Chromosomes store genetic information. </u>
<u></u>
All the genetic information within the eukaryotic cell is preserved as helical DNA within the nucleus. This DNA is tightly wrapped around histones as chromosomes.
Further Explanation:
DNA sequences contain genes that may have different forms called alleles. The genotype of DNA is transcribed into mRNA and subsequently translated into amino acids that are linked together by rRNA to form proteins that form the phenotype of an organism. Mutations in the DNA sequences affect the corresponding mRNA and therefore the encoded protein
Spontaneous changes that occur within the genome during the cell division process, called mutations. These errors occur as copies of DNA are produced inside the cell; mutations can range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.

The first can be filled with an element and the second blank can be filled with a compound.
Iron is an element as it contains only one kind of atom, which combines with the oxygen from the air to produce rust, that is, iron oxide. The rust comprises two kinds of atoms, which signifies that it is a compound. A compound refers to a molecule that comprises at least two types of atoms. In the case, iron oxide is a compound as it comprises Fe and O atom.

Explanation:
<u><em>7.</em></u>
Acomodation is the process in which the lens adapt to the distance of the object you look at.
During acomodation The lens changes shape and during the pupil reflex the pupils changes size so the answer is <u><em>C</em></u>
<u><em>8.</em></u>
The cerebelum is not attached to the spinal cord, but to the brainstem through cerebellar peduncles
medulla oblongata is part of the brainstem and it is attached to the spinal cord so the answer is <u><em>B</em></u>
<u><em>9.</em></u>
Insulin is a hypoglicemiant hormone that stimulates glycogenesis which is the synthesis of glycogen from glucose, hence the answer is <u><em>C</em></u>
<u><em>10.</em></u>
You get a fight or flight response which is mediated by adrenaline.<u><em> B</em></u>
<u><em>11.</em></u>
Adrenaline increases sweat production and decreases digestive activity so the answer is <u><em>A.</em></u>
I think it’s 2 , 3, and 4
Hope this helps!
