Answer:
Wildfire
Explanation:
The wildfires are one very devastating occurrence that can appear both naturally and be caused by humans. Naturally these fires occur because of high temperatures and drought, and because of thunders. When they occur, they spread out very quickly and it is an uncontrolled fire. It manages to burn down very large areas of grasslands or forests, moving very quickly and being extremely difficult to put it under control. While the wildfires are very destructive, there's also a positive from them, as they leave behind lot of ashes, and the ashes fertilize the soil, providing the basis for the growth of new vegetation.
Answer:
The answer is B - Tap water can be found in the natural environment, but what the lab technician is testing is if there is lead in the water. This part is not related to biology therefore making B the answer.
Explanation:
Biology is the study of living organisms and life.
Every other answer is related to Biology.
A - A vitamin that helps with vision - this will affect the human vision to become better after taking it; this relates to biology because it involves the interaction of humans and the human body system.
C - Change of environment - this deals with the bird's environment and how they live and breed, which is in biology
D - Growing coffee to reduce harm to the rainforest - this deals with biology because it is taking about the environment and how certain changes will affect how it will thrive.
E - DNA - this is involved in human and other organism's systems and is related to biology.
I believe that I know what you are talking about however a better layout or source would be nice.
3:I’m sorry I’m not really sure how to answer this one but I’m going to assume that you mean from dark to light. So they liked this time period because the trees were darker due to pollution, this made the darker moths survive from predators while the lighter color moths would be eaten, over time, natural selection would do its course and the whole population of moths would be dark.
4:Well I kind of already answered this but the majority of them were dark because the lighter ones would not be camouflaged therefore making them be easier target for predators and makes the darker moths breed out the lighter ones.
5:Well giraffes cannot live without food so the giraffes with shorter necks would slowly die off making it so only the long necked one would be able to reproduce with babies which would also have long necks, over a long course of time, the shorter necks would be completely gone.
6:Well I wouldn’t say they “grow” longer necks. It’s more like genetic mutation made it so random giraffes would get longer necks then others, since giraffes live in an environment where they have to have long necks only the giraffes with that genetic mutation would survive, and as a said, the longer neck giraffes could only breed with the other Long necked giraffes cause those are the only ones that could survive.
