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.

If natural selection changes then the phenotypes within a population changes over time because natural selection acts on phenotypes instead of genotypes .
Answer:
f. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where one strand is already methylated and thus correctly methylated daughter strands after replication.
Explanation:
DNA methylation is the addition of methyl group to DNA.it is an example of EPIGENTICS mechanism in genetics( epigentic refers to modification of expression of genes instead of altering the gene codes),
The objective of this mechanism is to modify the function of the particular GENE, therefore affecting the expression of the gene,
Answer:
it means that something does not allow fluids to pass through
