Answer:
a. True
Explanation:
Osmolarity is a measure of solute concentration, that is, it indicates how much solute there is in a liquid. As we know, osmosis is the movement of solute across the cell membrane, where the solute passes from the more concentrated side to the less concentrated side. Osmolarity is directly linked to this concept, but it is not able to indicate the direction of movement of the solute. This is because the solute will only pass through the membrane if it is a penetrating solute. Non-penetrating solutes do not have the ability to move through the membrane, even though the osmolarity of the liquid is high.
Answer:
Why would a plant cell have a chloroplast while an animal cell wouldn't? Chloroplasts are used to make food through photosynthesis. Plant cells make their own food, while animals do not.
Create a diagram that shows the dominant on a X-axis and the recessive on the Y-axis. Then simply combine the each dominant and recessive. You should end up with Xx, Xx, Xx and Xx
