Answer: Contractile vacuole of amoeba will shrink/contract when the organism is placed in sea water.
Contractile vacuole is a subcellular structure ( mainly found in protists) that is involved in the regulation of water quantity inside a cell.
As we know that water always flow from a hypotonic ( where solute concentration is less) to a hypertonic ( where solute concentration is more) solution. Sea water is a hypertonic solution as the concentration of salt is very high. Therefore, in this case, water will flow from contractile vacuole to outside of the organism.
Thus, contractile vacuole of amoeba will contract as it will lose water when placed in sea water.
Answer:
Add native plants to a suburban garden because you are adding already flourishing wildlife
Sea Urchins are primary consumers because they eat the kelp
Sun -> Grass -> Rabbit because grass lives off of photosynthesis from the sun and rabbit eats the grass
I think there would be more biomass in grass because there is a lot more spread throughout the savannah while elephants are way bigger there is less of them.
True if you are talking about an isotonic solution
Answer:
Option (A).
Explanation:
Cell membrane or plasma membrane is made up of lipids and proteins with the small amount of carbohydrates are attached to it. This membrane maintains fluidity and separate cell's environment.
Small non polar and uncharged molecules can easily pass through the cell membrane by the process of diffusion. Carbon dioxide and water are small molecules that can easily pass through the membrane.
Thus, the correct answer is option (A).
