Homozygous is a condition in which two identical alleles are present at a particular locus.
A condition in which an individual has inherited the same DNA sequence for particular gene from both their biological father and their biological mother.
An allele is defined as a variant form of a gene or one of two or more than two DNA sequences occurring at a particular gene locus.
Genes are made up of information required to produce different proteins.
Therefore,the presence of a recessive gene can be detected only if the individual is homozygous (aa).

Flatworms possess excretory organs known as nephridia. Specifically as annelids, flatworms possess a variant known as metanephridia.
This question is pretty vague and confusing.
People who use complex tools like plows, irrigation, and fertilizers to grow domesticated plants are called farmers, it is a large scale activity and it´s use to obtain food from the earth, we also have horticulture, does not require hundreds or thousands of acres of land, horticulture is also important, but is more limited to the domestic and individual context, and finally it is much cheaper because it is not done at large scales like the Agriculture.
