The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )
Given that the substance have pH ; 3 and 6
To prove the statement above we will make use of the pH formula
pH = -log(H⁺)
<u>for substance with </u><u>pH = 3</u><u> </u>
3 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻³
<u>for substance with </u><u>pH = 6</u>
6 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻⁶
Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

Answer:
The correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
Explanation:
Isotonic environment is an environment the amount of solute concentration is equal on both side of the semipermeable membrane or the cell. in such condition there would be no water movement towards particular direction or will take place and as there is no water movement so there would be no change in shape or size of the cell. The osmotic pressure in an isotonic environment would be same on both side of the membrane.
Thus, the correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.

The answer is hypothalamus. The hypothalamus is a bit of the cerebrum that contains various little cores with an assortment of capacities. A standout amongst the most critical elements of the hypothalamus is to interface the sensory system to the endocrine framework by means of the pituitary organ.
The hormones from the hypothalamus represent physiologic capacities, for example, temperature direction, thirst, hunger, rest, inclination, sex drive, and the arrival of different hormones inside the body. This region of the cerebrum houses the pituitary organ and different organs in the body.
