Answer:

C

Explanation:

C is the best answer. The endocrine system releases and controls hormones, which are basically just signals sent through the body.

These hormones regulate homeostasis, which is how your body stays at regular levels / stays the same. It keeps your body at steady conditions.

<h3>Hey Mate Here Is Your Answer:-</h3>

<h3>C- Diffusion</h3>

Reason:- The Mechanism of Diffusion In the case of food coloring in water, the water is the solvent while the food coloring is the solute. Once they've mixed, they make a solution. Diffusion takes time, though how much time depends on the kinetic energy of the molecules randomly bouncing among each other.

How many moles of MgCl2 are there in 319 g of the compound?
Leokris [45]

Hey there!:

Molar mass MgCl2 = 95.2110 g/mol

So:

1 mole MgCl2 -------------- 95.2110 g

moles MgCl2 ---------------- 319 g

moles MgCl2 = 319 * 1 / 95.2110

moles MgCl2 = 319 / 95.2110

=> 3.350 moles of MgCl2


Hope that helps!

Which of the following statements concerning the process of spontaneous folding of proteins is false?
Luda [366]

Answer:

(A) It may be an essentially random process.

Explanation:

The natural folding process of protein can be defective in several human infections and it usually comprises the initial generation of extremely compact state. It may also involve the systematical reduction in the range of conformational species and the initial generation of local structure. Therefore, the only false statement is option (A).

What is the ph of a solution with hydrogen ion concentration of 0.001m?
lys-0071 [83]
Find the pH using the concentration of hydrogen ions [H+] of 0.001M (molarity) by taking the negative log of the value:

-log[H+]=pH
-log[0.001] = pH
-log[1x10^-3]=pH

The following list contains some common polyatomic ions. Using the charge on these ions and the idea of valence, predict the for
SSSSS [86.1K]

Answer: Na_2CO_3 or Sodium carbonate.

              KMnO_4 or Potassium permanganate

Sodium ion carries 1 + charge whereas carbonate ion carries overall charge of -2. So for every carbonate ion, two sodium ions combine to balance the charges and thus form a stable compound, Na_2CO_3

Potassium ion carries 1 + charge where as permanganate ion carries overall charge of -1. So for every permanganate ion, one potassium ion combines to balance the charges and thus form a stable compound,  KMnO_4

The predicted formulas are shown in the attached image.
