Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination. Meiosis is important because it produces gametes, female or male germ cells.
Answer/Explanation:
Essential nutrients such as nitrogen, phosphorus, at specific moderate level are needed for the overall functionality of the aquatic ecosystem. However, when excess of these elements infiltrates the aquatic ecosystem, the nutrient overload causes a surge in the growth of aquatic plant. For example, algal bloom. These increased growth of aquatic plant further takes up space and oxygen, prevents sunlight and later leads to what is known as "dead zone". It is a condition of an ecosystem having little or no biological activity. Aquatic life is impacted negatively when this occurs.
These are the changes that occurs as a result of nutrient loading.
Darwin was spurred to finally publish his theory of natural selection by the writings of C. WALLACE
Darwin was writing up his theory in 1858 when he received an essay from Alfred Russel Wallace, who was in Borneo, describing Wallace's own theory of natural selection. Joint publication of Darwin's essay together with Wallace's paper was immediately prompted but received little notice from the public.
The public's disregard of their work spurred Darwin to write an abstract of his work which was published in 1859 as his book "On the Origin of Species".
Answer:
E. They’re a safer fuel to use than hydrocarbons.
Explanation:
Gas hydrates have an advantage over other forms of hydrocarbon fuel because it produces less pollution. The gas hydrates are clean energy, which contain pure methane and less number of harmful gases as compared to other fossil fuels. Due to this gas hydrates, less environmental pollution is produced as compared with coal, oil, natural gas and fuels etc.
