<h2>B) is the correct option </h2>

Explanation:

  • Succinate dehydrogenase is the smallest component of electron transport chain and consists of four different subunits including FAD, 3 Fe-S centers
  • It catalyzes oxidation of succinate to fumarate and electrons released transferred to ubiquinone
  • Succinate dehydogenase transfer electrons from succinate to ubiquinone via FADH2 thus this complex directly links tricarboxylic acid cycle to electron transport chain
  • Activity of succinate dehydrogenase is inhibited by malonate which is a competitive inhibitor as a result oxidation of succinate to fumarate will not occur and hence concentration of fumarate will decrease

In a species of bird, the allele for the striped trait is recessive to the allele for the speckled trait. Suppose that a coastal
mylen [45]

Answer:

The answer is "0.42"

Explanation:

Please find the complete question in the attached file.

Coastal community striped allele intensity = q = 0.62

Landlocked community, strip intensity allele=q'=0.40

Its eliminated allele frequency for movement = q"=0.42 \ in \ indoorscommunity And now in the sturdy vineyard optimum communities, genotype frequency of stripped characteristic (heterozygous device) in coasts=q_2=0.39

Heritable (striped) allele frecency:

\to q=\sqrt{q_2}

      =\sqrt{0.39} \\\\ =0.624 \\\\ =0.62

(round up to the closest cent) is therefore the only frequency of coastal people.

The genome of pulling function in host population= q'_2=0.16 Heterozygous feature regularly.

Therefore the inland community rate of recessed (striped), allele rate:

\to q'= \sqrt{q'_{2}}= \sqrt{0.16}=0.40

Following migration;

Its percentage of coastal migrants:

m=10\% \\\\

   = \frac{10}{100} \\\\= 0.1

Coastal population Non-immigrant percentage of coastal residents:

=1- m\\\\=1-0.1\\\\ =0.9

Stripping coastal community of allele rate after immigration:

(q")=\text{(stripping of migrant only freq)}\times (m)+\text{(stripping allele baud rate for non-immigrants)} \times ( 1-m)

       = [q \times m]+[[q' \times(1-m)]\\\\=(0.62 \times 0.1)+(0.40 \times 0.9)\\\\=0.062+ 0.36\\\\=0.422\\\\=0.42

When are organelles like mitochondria and endoplasmic reticulum divided up between daughter cells?
MatroZZZ [7]

Answer:

Anaphase

Explanation:

During anaphase, cytokinesis – which is the pinching off of the cell membrane – the organelles which duplicated during the prophase are roughly equally divided between the two dividing cells. This is because these organelles are well distributed across the cytoplasm of the mother cell.
