Solar energy technology is currently very expensive, but it is completely renewable and non-polluting. New advances in technology will hopefully make it cheaper in the future.

Which characteristic most likely describes a mushroom but not Thermus aquaticus?
Lunna [17]

Eukaryotic is the characteristic most likely describes a mushroom but not Thermus aquaticus.

<h3>Mushroom belongs to which domain?</h3>

Any member of the eukaryotic group of organisms, which also includes the more well-known mushrooms and microbes like yeast and mold, is referred to as a fungus.

One of numerous thermophilic bacterial species that are a part of the Deinococcota phylum that can withstand high temperatures is Thermus aquaticus. Bacteria are classified as prokaryotes, which are unicellular life forms. Prokaryotes lack a membrane-bound nucleus and other internal components.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
