The right answer is ISOTONIC contraction (not isometric)
During an isotonic contraction, the length of the muscle varies but not the tension. For example, an athlete achieves (approximately) isotonic contraction when he lowers an extremely heavy weight, at a slow and constant speed, against maximum resistance.
I believe it is C: Physical state of the atmosphere at any given time and place
The volume of the unknown solution obtained from the given standard curve is 2.57%
The linear equation produced by the standard curve is :

- y = absorbance ;
- x = concentration in percent (v/v)
Unknown Solution with absorbance value of 0.35 ;
Input the value of y into the equation.

Collect like terms


Divide both sides by 0.136



Hence, percentage by volume of the unknown solution will be 2.57%

Answer:
The answer is D.
Explanation:
It occurs continuously in the cells of all organisms and often involves an exchange of gases. There are 2 types of cells, 1 is Eukaryotic, which holds a nucleus, and the 2nd is Prokaryotic, which do not. Prokaryotes are single-celled organisms.
