Answer:
B
Explanation:
Meiosis produces gametes that contain one complete haploid set of chromosomes
Meiosis is a reduction division, where the number of chromosomes in the daughter cells is reduced to half as compared to the parent cell. This set of chromosomes is called a haploid set or genome. The reduction from diploid to haploid occurs during Anaphase I of meiosis I, where homologous chromosomes separate and enter into two different cells. Meiosis takes place only in reproductive cells that divide to form gametes
So, the correct answer is 'Meiosis produces gametes that contain one complete haploid set of chromosomes'

Answer:
Nitrogen-fixing bacteria will significantly outnumber those incapable of fixing nitrogen
Explanation:
Nitrogen-fixing bacteria are capable of growing in a medium lacking organic Nitrogen. They convert (fix) atmospheric Nitrogen (Nitrogen is abundant in air) into organic substrates. Hence, they will grow in the enrichment medium described. This is the kind of medium used to isolate nitrogen-fixing bacteria.
Non-nitrogen fixing bacteria require an organic form of Nitrogen for growth. Hence, in a medium with no nitrogen, they will rely on the Nitrogen fixers. This means delayed growth for them.
A culture medium also has limited nutrients, so the slow growers will have little or no nutrients left.
Therefore, the Nitrogen fixers will have competitive advantage and significantly outnumber those incapable fixing nitrogen.
Hyperglycemia is a condition, in which the blood glucose level reaches above the normal levels. this condition is caused by the deficiency or inactivity of the insulin. Hyperglycemia occurs when the cell is not able to absorb sugar from the blood, as a result, a lack of sugar in the cells occurs.
In case of absence of sugars in the cells, the cells use fats as a source of energy. the metabolising of the fats result in the increase in the fatty acid levels in the blood. the presence of the fatty acids above than the normal level causes the lipedemia.
Hence, the hyperglycemia increases the risk of lipedemia.
It is due to the electron transport chain that is located in the mitochondria
1) Pulmonary Circulation:This is the process where
deoxygenated blood is carried away from
the right ventricle of the hearth while oxygenated blood is returned to the
left ventricle and atrium of the heart.
2) Heart: It is a muscular organ that pump blood through the blood
vessels of the circulatory system.
3) Systemic vain: <span>this is a vain that drain into the right right
atrium </span>
4) Physical exertion:It the expenditure of energy expended during physical
activity.
5) Vasoconstriction:It can be defined as the narrowing of the blood vessels which
result into contraction of the muscular wall of the vessels most especially
large arteries and small arterioles.
6) Vasodilation: This is when blood vessel is widening and result in
relaxation of smooth muscle cell within the vessel walls.
