Answer:
The structure of mitochondria contains the foldings in the inner side called "cristae" which increase the surface area of the mitochondria. The cristae are important to mitochondria as well as cell as cristae embody the ATP synthase enzymes which help in the formation of the ATP molecules.
Heart cells require more energy to pump the blood from the heart to the body so it needs a more mitochondrial number in the cells with more infoldings to synthesize more ATP.
Answer:
the cell combines oxygen molecules to provide energy for use in cellular respiration
Topsoil is the A horizon in figure 7-1.The most leaching of minerals occurs from the A horizon into the B horizon. The C horizon shown in figure 7-1 is most like the parent soil, and <span>the A horizon in figure 7-1 contains the most humus.</span>
Answer:
24%
Explanation:
The given genetic trait is homozygous recessive and the frequency of homozygous recessive genotypes in the population is 2%.
Therefore, frequency of homozygous recessive genotypes (q2) = 2% = 0.02
Frequency of homozygous recessive allele (q) = square root of 0.02 = 0.141
Since p+q =1 (here, p = frequency of dominant allele).
So, p= 1-q = 1-0.141 = 0.859
The frequency of heterozygous carrier genotypes in the population = 2pq = 2 x 0.141 x 0.859 = 0.24 or 24%
All prokarytoic cells replicate through binary fission.
