If a red blood cell is placed in a hypertonic solution, the cell would shrink.
Hypertonic solution means that the solution has a lower water potential than the other side (which is the cell's cytoplasm in this case), and by that, water molecules would have a tendency to flow from a region of higher water potential to a region of lower water potential. This movement of water molecules is called osmosis. But note that a semi-permeable membrane (a membrane which can decide what substances can go in and out, the cell membrane is an example) has to be present in osmosis, or else the movement may be regarded as diffusion.
As the water molecules flowed away from the red blood cell cytoplasm, the cell loss so much water that the membrane has nothing much to hold and thus the cell shrinks.
Answer: Rougher Surfaces
Explanation: Rougher surfaces have more friction between them than smoother surfaces. The rougher surface of the soles of the shoes causes more friction and slows you down.
If only a single member of a pair of chromosomes is present in a cell it is a haploid condition and is most likely a reproductive cell.
Hope this helps!

Answer:
c. autotrophs and animals are heterotrophs
Explanation:
There's many differences between the plants and the animals, be it their physical appearance, way of live, how do they function, their requirements for survival. One of the major differences between the plants and the animals is that the plants are autrotrophs, while the animals are heterotrophs. The autrophs are the organisms that are able to produce their own food, thus they are producers, meaning that they do not need nutrition from other organic sources. The heterotrophs on the other side are the organisms that are not able to produce food for themselves, but instead they get their food through consuming of other living organisms, making them primary, secondary, and tertiary consumers.
