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.

Answer:

d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days

Explanation:

In an experiment, two groups exist as follows: experimental group and control group. Experimental group is the group that receives the experimental treatment (independent variable) while the CONTROL GROUP is the group that does not receive the experimental treatment.

In this experiment, the experimental treatment is the CAFFEINATED SODA (contains caffeine). Hence, the appropriate control group for this experiment will be the group that does not drink any soda (whether caffeinated or decaffeinated) or other caffeinated beverages for 10 days.

Answer:

The options

a. sympatric speciation; vicariance

b. allopatric speciation; vicariance

c. sympatric speciation; dispersal

d. allopatric speciation; dispersal

The CORRECT ANSWER IS d.

d. allopatric speciation; dispersal

Explanation:

Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).

Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.

In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
