Fudgin [204]

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.

Answer:

Option D = 3.4 g/mL

Explanation:

Given data:

Volume of water = 21.2 mL

Volume of water + object = 27.8 mL

Mass of object = 22.4 g

Density of object = ?

Solution:

First of all we will calculate the volume of object.

Volume of object = Volume of water+ object - volume of water

Volume of object = 27.8 mL - 21.2 mL

Volume of object = 6.6 mL

Density of object:

d = m/v

d = 22.4 g/ 6.6 mL

d = 3.4 g/mL

However, species facing such climate change move from that habitat to another for their survival and spread there. While such crops have been identified that adapt the climate changes and continue to grow in that environment to.
