Answer:
In a diploid organism there are two copies of most genes.
The versions of the genes are called alleles.
Explanation:
Hello!
The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).
When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.
Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.
In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.
The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.

Answer:
You would find the greatest variety of species in the tropics, and coral reefs. The Amazon basin in South America has the largest area of tropical forests where you could find the most variety of species.
Explanation:
Hypertonic environment
<h3>
How do salts and sugars preserve food?</h3>
Salts and sugars work to preserve foods by creating a hypertonic environment. Salt and sugar will remove the water from the bacteria or fungi and they will not be able to proliferate. Loss of water results in plasmolysis, or cytoplasmic shrinkage.
<h3>What is hypertonic solution and plasmolysis?</h3>
Compared to another solution, a hypertonic solution has a higher solute concentration.
Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. The live protoplast violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.

The hydrogen bonding of nucleotides into a new DNA molecule is facilitated by enzymes. Hydrogen bonding is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pairs forms two hydrogen bonds while the C-G pair forms three. The enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds.
Inability of dense irregular connective tissue to form properly will affect the formation of organs and the skin.
<h3>What is connective tissue?</h3>
Connective tissue is the tissue that provides supports, and gives structure to other tissues and organs in the body.
Connective tissue is made up of cells, elastic fibers, and collagen.
The dense irregular connective tissues are distributed throughout the body are important in the formation of the skin, the eyes and walls of organs.
