Answer: e. 2.5 ml
Explanation:
According to the dilution law,

where,
= concentration of stock solution = 20X
= volume of stock solution = ?
= concentration of required solution= 1X
= volume of required solution= 50 ml


Thus 2.5 ml much of a 20X tricaine stock solution is needed to dilute in order to make your solution.
Answer: b. the work rate or oxygen uptake where there is a systematic rise in blood levels of lactic acid
Explanation:
Currently, the anaerobic threshold is one of the most commonly used parameters, both as an indicator of physical performance capacity and training prescription, and there is evidence that performance in continuous and prolonged exercises correlates better with the anaerobic threshold than with maximum aerobic power. The anaerobic threshold can be understood as the point of imbalance between lactate production and removal (blood lactate threshold).
A diploid cell is a cell that contains two sets of chromosomes. Each
chromosome pair is considered to be one set of homologous
chromosomes. ... Gametes are haploid cells . During sexual
