The correct answer is:
b.The benefits outweigh the disadvantages.
Explanation:
Natural changes to the ecosystem transfer to the environmental phenomenon that occurs naturally. Natural changes hold floods, volcanic activity, hurricanes, dehydration, and earthquakes. They can be deadly, but they also have benefits.The benefit of the flood is, for example, contributing nutrients to the soil that were wanting. Also, there may be the relocation of fishes and organisms existing in water bodies, which develops the ecosystem.
As such, it is a Carcinogen which is basically just a substance that is known to cause cancer.
Hope this helped :)
Answer: Option B) Coelom
Explanation:
Hydrostatic skeleton is the type of skeleton possessed by soft-bodied animals such as earthworms and sea anemones. Fluid is secreted to fill the cavity spaces (coelom) in their body. The fluid then presses against the muscular body wall, causing the muscles to contract exerting pressure against the fluid thereby causing motion
Thus, coelom is the fluid cavity of the earthworm that gives it a hydrostatic skeleton
