Answer: second

Explanation:Early humans most likely experienced changes in climate forcing migration to find animals for food, changes in climate alternating rivers with droughts and floods and changes in environment causing animal habits changes.

Explanation:

All the changes that early humans could have experienced, I think, are related to the changes that animals and the lands could have suffered. They lived much more closer to them than we do now; now we sometimes don't realize how global warming is affecting our planet because we are not that close to the lands and the crops and we don't usually raise animals for our consumption, we just buy at the shop. But, early humans could sense every change related with that because this was the way they lived. So, migration to find animals, changes in climate alternating rivers with droughts and floods and changes in animal habits are the ones I believe they could have suffered.

Which type of solution will cause cells to swell, or even to burst?

Inga [223]

Answer:

(b) Hypotonic solution

Explanation:

Any solution having lower osmotic pressure as compared to another solution is called as a hypotonic solution and the reason that a solution is hypotonic is that it has more water and lesser dissolved solute in it.
If a cell is placed in a hypotonic solution, the amount of water content in the cell would be lesser as compared to that of the solution and hence, the water will enter the cell due to which the cell will swell and may even burst.
The water molecules can enter the cell through the semipermeable membrane and in case of plant cells, the presence of cell wall may prevent it bursting, however, the animal cells lack the cell wall and hence if kept in hypotonic solution for long these cells may burst.

An unusually cold winter causes the squirrel population to decrease. This is an example of temperature as a

levacccp [35]

Answer:

Most likely B

Explanation:

A - Carrying capacity is the amount of a species that can live in a given area with the given resources, weather does not apply.

B - Limiting factors are things such as food, mates, and competition with other organisms for resources, which can limit the maximum population. Temperature can be applied here, it is the best option.

C - Climax community is when an area's ecosystem is stable, so the term makes no sense used here.

D - To be honest I have no clue what this is. But making an assumption from the term, the winter being "unusually cold" does not make it a "pattern". So I don't think it's this option. I could be wrong, but I assume this is not the right choice.
