Answer:

telomere

Explanation:

Telomeres are structures or heterochromatic regions that are located at the end of each DNA strand and helps in protecting the chromosome. They prevent strands of DNA from being damaged which can result to destruction of cell functions.

These heterochromatic regions consists of repetitive nucleotide sequences, and they play a major role in preventing the chromosomes from deteriorating or fusing with other chromosomes. In general, telomeres play an important role in the preservation of genome information.

In an animal cell, which two cell structures do newly-synthesised enzymes have to pass through to reach the external environment
ss7ja [257]

Answer:

Ribosomes, Cell membrane

Explanation:

Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.

Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.

For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.

Answer: A change in allele frequencies caused by random events

Explanation :<u>Genetic drift refers to a process which occur due to sampling error from preceding generations that lead to a change in allele frequency by chance alone within a population.</u> It is a random process which  leads to large significant changes within a population over a short period of time. The rapid changes are due to increasing inbreeding coefficient s and homozygosity from the removal of alleles.

It is peculiar to a population which is synonymous with regular cycle of extinction and recolonization. Therefore, together with evolution, mutation and migration, <u>it is one of the driving mechanism of EVOLUTION.</u>

It is caused by;  

Static or recurring small population sizes,  

"Bottlenecks” form of population, that is drastic reduction in population size;

Repopulation from a small number of individual-FOUNDER EVENTS.

<u>Measurements of Genetic Drift </u>

The magnitude of genetic drift within a population depends on the effective population size for the population.This is represented as Ne.  It is a theoretical number use to quantify the number of genetically distinct individuals that contribute gametes
