A particular species of fish were split by the formation of the Isthmus of Panama a long time ago. The fish developed changes in
Aloiza [94]
<span>This is speciation. In this process, two distinct species are formed through the intervention of some means such as differing environments or locations. This is done typically as a way of staying evolutionarily competitive in the area in which the species resides. The new species would be the exemplar of that which is best suited to the new conditions.</span>

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.

Researchers are studying the abnormal activity of kinases in relation to cancer. Theoretically, how might researchers use signal
myrzilka [38]

Answer:

I am pretty sure that the answer is A.

Explanation:

Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.

I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or  growth factors (not in the answer choices). Since one of the factors that  leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!
