The answer is <span>Conduct a test cross with a purebred recessive plant.
</span>
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>

The correct answer is A: cell
Answer:
I believe your answer is fertilization.
Answer:
When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.
Explanation:
Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.
