The answer is; D
Radioactive waste poses a serious challenge to the environment. Any leakage of the waste is risky because the radioactivity can flow up the food chain and it also takes time for it to decay and become less harmful. Therefore, its effect can be felt over many generations. Therefore, safe storage of radioactive waste is a challenge (and can be very expensive) and a deterrent for pursuing the potent energy source.
Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
The explanation is given below
<u>Explanation:</u>
Hawaii's Big Island:
Mountain barriers play a significant role in modifying the air masses and topography affects the distribution of precipitation.
The orographic effect takes place on Hawaii's Big Island (i.e) the rising air makes the windward side of the mountains rainy and leeward side of the mountains dry.
Island of Maui:
In the Island of Maui, the high mean of rainfall is found on the windward side of the mountain slopes and the low mean of rainfall is found on the leeward lowlands and on upper slopes of the highest mountains.
Answer:Succession as progressive change in an ecological community. Primary vs. secondary succession. The idea of a climax community.
Explanation:
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
