Answer: a. begins to accumulate significantly at a point that is about 55-65% of Vo2 max

Explanation:

Lactate is produced in the body after the burning of glucose (glycolysis), to supply energy without the presence of oxygen (lactic anaerobic metabolism). In long-term physical activities, oxygen supply is not always sufficient. The organism seeks this energy in alternative sources, producing lactate. For the average human, blood lactate begins to accumulate significantly at a point that is about 55-65% of Vo2 max. The accumulation of this substance in the muscles can generate a hyperacidity, which causes pain and discomfort soon after exercise. Thus, the determination of lactate blood concentration allows indirect evaluation of the metabolic acidosis of the exercise, being one of the diagnostic tools used by Exercise Physiology.

Atoms with a low ionization energy give up their outer valence electrons with ease true or false

umka2103 [35]

Answer: The given statement is true.

Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.

General equation of ionization energy is given by:

$X(g)\rightarrow X^+(g)+e^-$

If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.

And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.

Hence, the given statement is true.

Which of these is an agent of wedging

worty [1.4K]

I would answer your question but i think you wanted to add options. next time you can just screen shot and actually i think you still can by pressing the edit button. And there are several types of wedges you could be talking about mechanical, frost, salt, etc.

You need to be a bit more specific. but i would be more than happy to answer your question. :)
