Answer:
true
Explanation:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size
hope this helps
Answer:
Animal cells are primarily in spheres or oblong shapes such as ovals. Plant cells are usually tubes or squares/rectangles. I have no idea what cells go into pyramids.
Explanation:
By binding to DNA it triggers the transcription of a specific gene.
Answer:
33%.
Explanation:
The 4% population is red-hair due to the recessive mutation in melanocortin 1 receptor (MC1R).
Since, the population is in Hardy-Weinberg equillibrium- laet the frequency of recessive allele with red - hair is 'q' and the frequency of dominant allele in the population is 'p'.
q=0.2
According to hardy-weinberg equillibrium
(p+q)=1
p=1-q
p=1-0.2
p=0.8.
The total population with non red hair is calculated by
=
= 0.64 + 0.32
= 0.96
The percentage of the population with non red headed carrier for MC1Rr is calculated by:
=0.32/0.96*100
=33%
Thus, the correct answer is (B).
ATP production would be stimulated. Positive feedback basically just enhances an original stimuli, so for example, blood clotting usually occurs at a lower rate. But when there is an injury, that blood clotting stimuli is enhanced to keep producing a large clot to make sure the wound is covered.
