quizlet chromosomes are composed of: please choose the correct answer from the following choices, and then select the submit ans

Anna11 [10]

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

What are 5 examples of coevolution from the movie Evolutionary Arms Race?

Step2247 [10]

Answer:

1. The adaptation of the garter snake to the increasing toxicity of the rough-skin newt

2. The development of antibiotic-resistance by the tuberculosis bacteria in prisoners in Russian prisons

3. The development of FIV-resistance in wildcats

4. The immunity to HIV in about 10% of caucasians due to mutations in their cells that occured among those who survived the Black Death.

5. The development of immunity to asthma in children exposed to livestock at an early age in Bavaria

Explanation:

Coevolution refers to the the evolution that occurs in two species of organisms due to the mutual interaction or interdependence of the two species. Due to this interaction among species, a change in one organism results in adaptive changes in the other organism as well.

Coevolution can occur is any of these relationships between organisms: predator-prey, mutualism, or commensalism.

In the movie, Evolutionary arms race, the following examples of coevolution were highlighted:

1. The adaptation of the garter snake to the increasing toxicity of the rough-skin newt.

2. The development of antibiotic-resistance by the tuberculosis bacteria in prisoners in Russian prisons.

3. The development of FIV-resistance in wildcats.

4. The immunity to HIV in about 10% of caucasians due to mutations in their cells that occured among those who survived the Black Death.

5. The development of immunity to asthma in children exposed to livestock at an early age in Bavaria.
