Answer:
B. Human activities and natural events can damage the environment.,
Explanation:
Human activities are those activities carried out by a human being. The environment is being degraded daily as a result of the activities of man as well as natural occurrences e.g earthquake, tsunami, wild fire etc.
Human activities also called anthropogenic activities that damage the environment include sewage pollution, burning of fossil fuels, oil spillage etc. Hence, according to this question, human activities and natural events can damage the environment.
Individual and public health are affected by environmental and genetic factors is a statement which reflects reality. Firstly, susceptibility to certain diseases usually or often runs in a family so that if there is say, diabetes in the father and grandmother for example, the son or daughter has more chances of getting it so this is a genetic susceptibility.. Also, some families are more prone to cancer so that given the right circumstances, cancer can develop. So it is usually a combination of both genetic and environmental causes that results in a disease. An example of public health could be when smallpox was deliberately introduced to the First Nations people in British Columbia, Canada back in the 1800's to decimate them and remove their resistance to the gold mining hordes. Since the First Nations had no anti-bodies to counteract such a disease unlike the white men who introduced it to them, then they easily fell prey to it and died within days of contracting it.
Answer:
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons of matter are converted into neutrinos, solar radiation, and roughly 4 x 1027 Watts of energy
Explanation:
The genotype would be X'Y for the father (he would be colorblind)
The genotype would be X'X for the mother (she would be a carrier)
The offspring would be X'X' _ X'X_ X'Y_ XY
The ratio would be 1:1 normal to colorblind

Synthesized RNA will remain. I believe this is because the polymerase allows the DNA to close up & that’s how it forms its double helix. Then the RNA chain is displaced and the DNA will soon be re-formed.
