How are DNA fragments separated using gel electrophoresis? ... A solution ofDNA molecules is placed in a gel.

A tree that has leaves that are shaped to help water drip off them would most likely live where?
Elena-2011 [213]

Answer:

The correct answer is tropical rain forests.

Explanation:

The hot and moist biome witnessed close to the equator of the Earth is the tropical rainforest. The largest tropical rainforests in the world are found in Africa, South America, and Southeast Asia. About 60 to 160 inches of rainfall is witnessed in the tropical rainforests throughout the year. Due to this, the leaves of the trees found in the tropical rainforests possess unique features that help them to survive.  

The leaves of the trees found in the tropical rainforest possess drip tips that help them to cope with the extreme amount of rainfall that takes place throughout the year. The drip tips help the drop of rains to run off briskly from the surface of the leaves. This adaptation helps the plants in the region to prevent the growth of bacteria and fungus.

maria [59]

Answer:

Sampling error may allow fixation of one form and the elimination of others in a small population.

Explanation:

It can be seen that in case of a small population size, there are high chances of the elimination or the fixation of the allele in the population when compared to the large population size. Also sampling errors are found in case of small population size that leads to the enhancement of the chances for fixation and also for the elimination of the allele. This large size population doe not have much effect. The random fixation of the either selective allele or the elimination of the disadvantageous allele occurs due to the genetic drift.

SO in order for the population size influenced the survival of both types of mutations , the sampling error may be allowed for the fixation of one of the form and the elimination of the other forms in the small population size.
