Answer:
During the process of gel electrophoresis, the DNA separates on the basis of charge to mass ration and forms bands as it moves towards the positive end of the gel.
If the electricity is kept running for too long, then the DNA will continue to run in the positive direction and might exit the far end of the gel. As a result, there will be no band formation due to which the experiment will become incorrect.
<span>During the development of
a gamete, the two alleles of the P generation separate. Each gamete carries one allele from each
parent which randomly pairs in the F1 generation. This mechanism repeats when
F1 plants cross and yield F2 plants. The
outcome of the F2 generation would then have new combinations of alleles which
can be different compared to the preceding generations.</span>
Answer:
yes, that is the answer.
Answer & explanation:
Gills are an adaptive structure for fish and other aquatic animals to survive in the aquatic environment.
They are blade-shaped and highly vascularized, allowing gas exchanges between the ambient water and the animal's blood.
Water enters the mouth and is led through the gills, being eliminated by gill slits, then oxygen is distributed in the blood to the animal's body.
