Answer:
This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.
Explanation:
Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
Explanation:
When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood. The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.

Large dose of folate increase the symptom of vitamin B12 deficiency . the vitamin B12 deficiency can lead to permanent damage of the spinal cord nerves and brain.
It can cause severe birth defects which is called neural tube defects. this defects include spinal, pifida . folate deficiency can also increase your chance of placental abrupt ion is a condition in which placental separate from uterus.
High dose of folate typically be remedied by taking supplement of both folic acid and vitamin B12. vitamin B12 works closely with vitamin B9 also called folic and folate acid which is help to make red blood cells and iron work better in our body.

All cells have selectively permeable membranes, which means that only they let certain important molecules inside the cell, while the others stay outside the cell.
This occurs by the process of diffusion or osmosis.
