Answer:
The answer is C
Explanation:
Homeostasis is, in my definition, maintaining normal levels. So, to maintain homeostasis of a heartbeat, the nervous system regulates heartbeats in order to prevent abnormal ones and to increase blood flow during exercise.
I will support the notion that the human body is made up of the four types of macromolecules which can be seen below:
<h3>What is a Macromolecule?</h3>
These are referred to the large molecules which are involved in the biochemical activities of the body and examples include protein, lipid etc.
All cells in the body however contain all the macromolecules because Protein acts as the building block for the cells while carbohydrates are usually stored in cells as glycogen. Lipids form part of the membrane and nucleic acids such as DNA are present in all parts of the body.

For a species of beetle, n = 20, a diploid cell would contain 40 chromosomes overall.
<h3>How do chromosomes work?</h3>
A chromosome is a long DNA molecule that houses all or some of the genetic code of an organism. In order to preserve the quality of the chromosome, chaperone proteins and histones, a type of packaging protein present in the majority of eukaryotic chromosomes, attach to and condense the DNA molecule.
<h3>What place do chromosomes come from?</h3>
The DNA that makes up each chromosome has been continuously tightly coiled around proteins called histones to support its structure.
<h3>Which of the four chromosomal kinds:</h3>
- Sub metacentric chromosomes.
- Chromatin that is acrocentric.
- The telocentric chromosomes.
- Chromatin that is metacentric.

Heterozygous
For example we cross AA which is Homozygous Dominant and aa which is recesive
(AA)×(aa)
Aa Aa Aa Aa
So the answer is hetrozygous
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.
