The events that caused the oceans to form are as the earth cooled, water condensed and the sun released a strong burst of water vapor.
<h3>How oceans are formed?</h3>
Oceans are formed millions of years ago when the water drained into the great hollows on the Earth's surface, the primeval ocean came into existence.
These two events are responsible for the formation of the oceans which is the primitive habitat of the aquatic ecosystem.
Therefore, the events that caused the oceans to form are as the earth cooled, water condensed and the sun released a strong burst of water vapor.

Survival of the fittest is another way to describe the roll it plays seeing as that the organisms best fitted to survive an area will and can produce more of the fittest species; the ones who are best fit will die
The answer is D, blood pressure between heartbeats
Genetically modified bacteria (recombinant bacteria) with the human gene for insulin is useful because after it’s being put in fermentation tank it starts to produce human insulin protein. The process of making recombinant bacteria includes DNA cloning.
A target gene, in this case, insulin gene, is inserted into a circular piece of DNA called a plasmid via restriction enzymes and DNA ligases. Recombinant DNA is then introduced into bacteria via a process called transformation. With the right conditions the bacteria that contains the human insulin gene, will start transcribing the gene and translating the mRNA to produce many molecules of human insulin protein.
Controlled population growth.
Explanation:
US is a highly developed country and it has expansive infrastructure and highly mechanized agricultural equipments. So first option is not a choice. Second, access to chemical fertilizers and pesticides in a country with such advanced agriculture infrastructure is very easy. Third US is well known for using GM crops.
US does not have a controlled population growth because if not the birth rate then migration of people to US is a major concern for that country. Thus, this will be a correct choice for the given question.
