Answer:
The correct answer is - 2. Helium.
Explanation:
Nuclear fusion is a reaction that involves the fusion of two or more atomic nuclei to make different atomic nuclei with subatomic particles and releases a huge amount of energy.
Two hydrogen molecules with one proton and one neutron fused together to make a larger helium molecule with two protons and two neutrons and release a huge amount of energy.
1H^2+1H^2 ====> 2He^4 + energy
Answer:
genetically identical somatic cells containing 46 chromosomes
Explanation:
Human somatic cells are composed of 23 pairs of homologous chromosomes, therefore they are composed of a total of 46 chromosomes.
Mitosis is a process of cell division. In humans this process originates from a a single mother diploid cell (46 chromosomes) , two diploid -and genetically identical- daughter cells. It is, two daughter cells each with 46 chromosomes
The daughter cells in mitosis are identical because, unlike the meiotic cell division, where haploid gametes are produced, <u>there is no genetic recombination in mitosis</u> and therefore there is no difference in the cells resulting from mitosis.
Answer:
vegetation and plant life
Explanation:
Answer:
The most probable result of the increasing concentrations of fertilizers in the prime rivers emptying into oceans is eutrophication followed by hypoxia. This will eventually result in less uptake of carbon dioxide and less release of oxygen.
The fertilizers are among the common pollutants, which degrade the quality of water. The fertilizers comprise chemicals, which are good for plants use, however, the excess amounts used in plants get run off and pollute the water bodies.
The fertilizers mainly comprise nutrients like phosphorus and nitrogen. When it rains, these nutrients get carried to the water bodies and results in algal bloom known as eutrophication. This algal bloom utilizes the oxygen in the water, leaving behind no or fewer levels of oxygen that hampers life of aquatic species.
