I hope this helps! If you have any doubts, feel free to ask.
An exothermic reaction is a chemical reaction that releases energy by light or heat.
Question:
a. Diffusion
b. Facilitated diffusion
c. Both
d. Neither
1. movement to area of lower concentration
2. movement across a membrane
3. steroid transport into cell
4. requires energy
5. movement assisted by proteins
6. glucose transport into cell
Answer:
The sorting is as follows
a. (1)
b. (5 and 6)
c. (1 and 2)
d. (4)
Explanation:
Diffusion is the movement of particles across a membrane from a high concentration region to one with a lower concentration of the diffusing substance
Here we have the correct sorting as follows
a. Diffusion
3. steroid transport into cell
b. Facilitated diffusion
5. movement assisted by proteins
6. glucose transport into cell
c. Both
1. movement to area of lower concentration
2. movement across a membrane
d. Neither
4. requires energy
