Answer:
In addition to the local control of blood flow, global control of blood flow including changes in cardiac output and control of arterial BP is mediated by the autonomic nervous system. Global neural control of arterial hypertension is essentially through the sympathetic nervous system (SNS).
Explanation:
From Google
Answer: Receptors.
Explanation: Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Answer:
At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.
Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.
DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.
DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.
DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.
The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.
