Question

1. in the image to the right, the molecules are moving from the left to right. using all the information provided, is the image an example of passive transport or active transport? how do you know? 8. could this represent facilitated diffusion? if so, how do you know? if not, how do you know?

Explanation:

• Question 7: Passive transport moves molecules from high to low concentration without energy. The image shows molecules moving from left (higher concentration) to right (lower concentration), which fits passive transport.
• Question 8: Facilitated diffusion (a type of passive transport) uses transport proteins. The image does not show any transport proteins (like channels or carriers), so it cannot be facilitated diffusion.

Answer:

1. Passive transport. Molecules move from high (left) to low (right) concentration (no energy needed).
2. No. No transport proteins (channels/carriers) are shown in the image.
