Organisms that live in an intertidal zone must be able to tolerate which changes to survive?

1 answer:

4 0

Organisms that inhabit intertidal zones must be able to tolerate radical changes in temperature, salinity, and moisture and also be able to withstand wave shock. Intertidal zone is the coastal area alternately exposed and submerged by tides. Tide pool animals and plants are well adapted to the intertidal zones. Some adaptations include; the ochre sea star can tolerate a longer time period exposed to air than many other sea stars. They regularly withstand up to eight hours of exposure during low tides.

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.

Identify the relationship described below:

Paha777 [63]

hi :)

The relationship described is predator-prey.

The orca is hunting and eating other organisms, which is known as a predator-prey relationship.

In case you need help with any more of these-

Mutualism is when both animals get something out of the relationship, for example, some kinds of shrimp get the food out of fishes teeth. The fish gets clean teeth, and the shrimp gets a meal.

Parasitism is fairly self-explanatory. This is when a parasite lives and gains from a host, while the host is harmed and could get diseases from the parasite.

Commensalism is when one animal benefits and the other isnt harmed nor benefited. An example of this is the remora fish which clings to the bottom of other fish when it gets tired.

Lastly, Competition. This is when two organisms compete for something they need to survive. For example, two lions could compete for a food source, such as a zebra. Usually, the strongest and fastest organism survives, or wins.

Alrighty, I hope this helped!!

Good luck with the rest of your assignment!!
