True

False

• Question 2

the substance doing the dissolving

• Question 3
45 seconds
Q.

What is a solvent

The one doing the dissolving

The substance dissoved in another substance

• Question 4
45 seconds
Q.

How do the particles move in diffusion?

From a region of low concentration to a region of high concentration

From a region of high concentration to a region of low concentration

From a region of low concentration to a region of low concentration

From a region of high concentration to a region of high concentration

• Question 5
45 seconds
Q.

How long does diffusion last?

Until the concentration of particles in the system is equal

(Select this answer and I swear i'll make it harder for you in the assessment task)

Until a region in the system has a greater concentration of particles than the other

Until the particles disappear from the system

• Question 6
45 seconds
Q.

What happens to the concentration of carbon dioxide in you cells when you exercise

Increase

Decrease

Remain constant

• Question 7
45 seconds
Q.

What hapens to the concentration of oxygen in the body cells when you exercise?

Increase

Decrease

Remain constant

• Question 8
45 seconds
Q.

How does the body remove carbon dioxide from the cells?

The body cells converts carbon dioxide into carbon monoxide

The body cells don't expel the waste, they store them for future use

The body cells expel the carbon dioxide through the use of the nucleus

The carbon dioide diffuses out of the body cells and into the bloodstream due to differences in the concentration gradient
