Answer:
Photosynthesis and respiration are similar in that they both produce ATP via an electron transport chain, biochemists and ATP synthase. In photosynthesis, ATP is produced in the light reactions by photo-phosphorylation through an electron transport chain, biochemists and ATP synthase in chloroplasts.
Explanation:
Both fungi and bacteria are very important for decomposition of organic matter. Decomposition is the break down of dead or decaying organisms. This allows nutrients from all trophic levels to re-enter the soil to be used by primary producers. Fungi are more effective decomposers compared to bacteria as they can <span>use their hyphae to penetrate larger pieces of organic matter, whereas bacteria are restricted to exposed surfaces. </span>
Answer:
a. The frequency of the g allele= 0.6
b. The frequency of the G allele= 0.4
c. The frequency of the GG genotype= 0.16 or 16%
The frequency of Gg genotype= 0.48 or 48%
Explanation:
According to the given information, the disorder is homozygous recessive trait. The frequency of the homozygous recessive genotype (gg) in the population (q^2)= 36% or 0.36
Therefore, the frequency of the recessive allele "g" (q) = square root of 0.36= 0.6
Since p+ q = 1
Therefore p= 1-q = 1-0.6= 0.4
The frequency of the dominant allele "G" (p)= 0.4
The frequency of the homozygous dominant genotype GG = p^2= 0.4 x 0.4 = 0.16 or 16%
The frequency of heterozygous dominant genotype Gg = 2pq = 2 x 0.6 x 0.4 = 0.48 = 48%
Answer: A) Black trait is dominant
B) The genotypes of the parents must be Bb
Explanation: Let B represent the allele for black colour and b represent the allele for white colour. If the offspring between 2 black mice show the ratio of 3 black mice to 1 white mouse, it then means that the two parents are heterozygous for black colour, that is each of them have one allele for black colour (B) and one allele for white colour (b). They both have a genotype of Bb.
Bb x Bb = BB, Bb, Bb, and bb.
This means 1BB : 2Bb : 1bb
BB is black, Bb is black while bb is white which gives a ratio of 3 black mice to one white mouse. For Bb to manifest as black, it means that B is dominant to b.
