Katen [24]3 years ago
7 0

Answer:

Cultivation of crops and tillage practices.

Explanation:

Farming of crops and tillage practices on the grasslands depleted grassland that are present across North America because the lands are converted and used for the production of food crops in order to fulfill the feed the existing population. More and more land is converted from grassland to the cultivation of crops that leads to lower area for the grazing of animals which results in decrease population of animals such as sheep, goat and cow etc which depends n these grazing regions for food.

In pan mixia, in the absence of migration, mutation, and selection the frequencies are A) Constant in genotype and phenotype B)
muminat

Answer: option A - Constant in genotype and phenotype

Explanation:

Pan mixia is a situation in which an individual is just as likely to mate with another randomly chosen individual as any other in the population

In a situation as described in the question, sexual reproduction is limited to organisms of the same habitat, thus the genetic variation is reduced to the BAREST MINIMUM.

This results in Constancy in genotype and phenotype

How could an error during transcription affect the protein that is produced?
Ahat [919]

Answer: An error during transcription could produce a shorter protein or induce changes in the protein's sequence.

Explanation: Transcription is the process of single-stranded RNA synthesis from a DNA template (gene). During this process, RNA polymerase reads the DNA template and synthetize RNA, keeping the sequence. The RNA sequence will be reading later by ribosomes and protein will be produced. An error in transcription could produce changes in codons that are sequences of 3 nucleotides that determine  aminoacids of the protein, and that would change protein folding and inactive it. Another possible result would be that  error in transcription produce a premature stop codon that cause a shorter inactive protein.

Which labeled placemark in the layers folder represents the stratosphere?
Leya [2.2K]
The atmosphere is divided into different regions, called layers. The layer closest to the surface is known as troposphere, after which comes the stratosphere. The stratosphere begins at an altitude of 10 miles above the surface of the earth and stretches up to 31 miles above the surface of the earth. It is the second layer of the atmosphere (beginning from the surface of the earth) and it is the region which contains ozone, which plays a vital role in stopping ultraviolet radiation from reaching the earth's surface.
