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 .

Leni [432]

Answer:

Francesco Redi's experiment was the first experiment that disproved the theory of sponatenous generation. He explained that life cannot originate from the inorganic or non living matter.

He placed the two maggots in two different jars. The one jar is uncovered and contains meats in which maggots appear. The another jar is covered and no maggots appear on meat. This explains that maggots flies eggs are not formed in the covered jar as eggs are not available for the life. Maggots do not originate from the meat.Life originate from the pre existing life.

Mutation is a random and non-adaptive process. This was first proven by:
s2008m [1.1K]

Answer:

Option (d).

Explanation:

Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.

Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.

Thus, the correct answer is option (d).
