How do wildfires help control plant disease? a. Wildfires are more likely to kill off plants that are likely to spread disease.
Bezzdna [24]

Answer:

d. All of the above

Explanation:

Wildfires are useful in controlling the ecosystem disturbed due to some diseases and insects.

With the help of wildfire, there will be a temporary loss in some region but it will lead to extraordinary growth.

Wildfire improves the soil quality by decomposing the organic material and renewing the soil nutrients.

There are chances of habitat loss but it will increase the production of food grazers.

(70pts) Recall the story of Three Blind Mice where the farmer’s wife cuts off the mouse tails with a carving knife. Because of t
omeli [17]

Answer:

What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.

What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.

What else can happen is the trait of tailless cannot  be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore,  there are no chances that tailless mice can born and nature choose it as a favorable trait.

In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.

Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>


Hope it help!
