Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm
Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC
Number of dominant alleles if length is
18 cm = 18-6 / 4 = 12 / 4 = 3.
F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.
seven 1. It is likely that there are gene pairs in this cross. There are
categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.

Answer:
A. Homeostasis allows organisms to regulate their temperature.
Explanation:
Homeostasis is a biological process through which the body of organisms try to maintain a relatively stable body conditions irrespective of the changes in the external environment.
<em>Homeostasis keeps body processes such as temperature, pressure, hydration, pH, etc. relatively stable. While some organisms maintain a stable body temperature by generating heat (endotherms), others do so by adjusting their body temperature to be in tune with that of the external environment (ectotherms). </em>
The correct option is A.
A new species of algae floating on the surface of a coastal zone, it is a type of <u>phytoplankton</u>.
Algae is an informal time period for a massive and various group of photosynthetic eukaryotic organisms. it is a polyphyletic grouping that includes species from a couple of awesome clades.
Algae belong to the dominion Protista whereas, fungi belong to the dominion Fungi. Algae are autotrophs, and Fungi are heterotrophs. Algae comprise photosynthetic pigments. Fungi are able to digest non-residing, natural fabric, and additionally absorb easy vitamins by the fungal hyphae.
A eutrophic lake is typically shallow with a smooth and mucky backside. Rooted plant boom is ample alongside the shore and out into the lake, and algal blooms are commonplace. Water clarity isn't right and the water frequently has a tea color. If deep is sufficient to thermally stratify, the bottom waters are devoid of oxygen.

Hello there!
The correct answer is tunicate.
Hope This Helps You!
Good Luck :)
Answer:
Imagine studying a cell. That cell has billions of things you can learn about. Now imagine 37.2 trillion cells each a little bit different but still similar. Now imagine that multiplied by all the different people there are on earth. Now then include all the other types of living animals.
That's biology
