The right answer is hyphae for the first gap, mycelium for the second gap.
The hyphae constitute the vegetative apparatus of the mushrooms, while the visible part, that which is improperly called mushroom, is in fact its reproductive apparatus.
Hyphae are less branched filaments consisting of a single cell that can be several centimeters long. They contain several nuclei and can sometimes be partitioned.
The mycelium is a part of the mushroom (composed by many hyphae), which is in the form of white filaments and grows about fifteen centimeters under the ground. It is this part of the mushroom that has therapeutic properties because the filaments of the mycelium are going to draw the minerals in the soil.
In the case of the gene that determines high cholesterol in the blood, the two alleles express incomplete dominance.
What this means is that the dominant allele is not completely dominant over the recessive allele. If the allele was completely dominant, even one allele would be enough to determine the individual's trait as dominant. But in the case of incomplete dominance between the alleles, the heterozygous individuals that have one dominant and one recessive allele are an ''in between'' phenotype.
The correct answer that would best complete the given statement above would be the first option. Coral reefs are built by a small organism called a polyp. The polyp creates the structure of the coral reef by building a CUP out of a calcium carbonate. The skeletons of these tiny corals s<span>ecreted by the lower portion of the polyp. Hope this answer helps.</span>
