Answer:
The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells.
Explanation:
When the vessels suffer vasoconstriction, the blood supply is decreased and in this way the heat of the body is maintained. The way this happens is because the blood can no longer reach the surface and therefore decreases outward heat radiation. The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells. There are several factors that cause vasoconstriction, internal or external. Environment is one of the external factors, and what happens to the penguins' feet is an example for it, since they are trying to preserve body heat to survive.
When the change of temperature in a space is measured and can be controlled to get a preferred temperature.
Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.
DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.
The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.
Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.
Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.
