Heart rate decreased suddenly and then MAP immediately fell because peripheral blood vessels were extensively vasodilated.
Explanation:
A VO2 max test is a clinical test done in a lab and is the ‘golden standard’ for measuring the potential and cardio-respiratory endurance of athletes and bikers.
It measures the oxygen carrying capability through a graded step test which determines the average power output. The maximal oxygen uptake along with cardiorespiratory responses is measured.
As per exercise physiology, the heart rate and cardiac output increases with exercise. When the potential is less, the resistance decreases, heart rate and mean arterial pressure also decrease

Answer:
This diagram depicts the phenomenon of DNA translation in the central dogma of life. Here are the labels
1. <u>RNA strand</u> because it is a sequence of four nucleotide A, G, C, U. It has Uracil, this is why it is RNA. Further, translation takes place when DNA is already transcribed.
2. <u>Ribosome</u> is a machinary for protein formation. This is because it provides right environment to transfer RNA to decode RNA strand into a protein sequence.
3. <u>Amino acid</u>: Each amino acid is carried by a transfer RNA (tRNA). The type of amino acid depends on type of tRNA. All proteins are mostly formed with 20 amino acids and so there are at least 20 tRNA.
4. <u>Polypeptide (protein) chain made up of amino acids</u>: It depicts multiple amino acids, which tRNA carries, and are bonded together through peptide bonds.
5. <u>Transfer RNA (tRNA)</u>: tRNA has a complementary sequence to RNA strand and thus it binds with right sequence. It carry an amino acid which is then bonded to another amino acid amino acid to make a polypeptide chain.
