Answer:A) form of gene

Explanation:

An allele is one of the different variants of a gene. It is one of the two or more genes found on the same locus on a chromosome which determines a specific trait in an organism. An allele can be dominant or recessive. A dominant allele is the allele that has the ability to mask the effects of a recessive gene when it is paired with the recessive gene while a recessive lacks the ability to express itself in the presence of a dominant allele. For a recessive allele to express itself, it must occur in a homozygous form.

Chick require energy from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers

Which of these pollutants is biodegradable?

vfiekz [6]

Answer:

Food waste

Explanation:

Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.

The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.
