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.

The white blood cell is called NEUTROPHIL. Neutrophils play important roles in the immune system; they move around the body via the blood stream and when they sense signals that foreign bodies are present, they move to the site of the infection and destroy them. They are among the first set of immune cells that defend the body against infection.
The answer to this question is salts, excess water, and sugars
Answer:
A
Explanation:
Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand.
Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and improving natural lighting indoors.
Oxygen molecules diffuse fast because the main gas in a cell in Carbon Dioxide its like if it was 99.9 percent carbon that .1 percent is oxygen and carbon dioxide being what it is. Automatically overrides the amount of oxygen. Basically it is nonpolar
