Answer:

A. The temperatures are too high.

Explanation:

A desert is a region with extremes of temperatures and little to no rainfall.

Organic matter are the remains of organisms that have died. They are a very important component of soils.

Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.

Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.

bekas [8.4K]

Answer:

We could feed them with another type of food free of silver salts.

Explanation:

When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.

If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.
