devlian [24]

Answer: All of them seem to apply.

Explanation:

A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.

B., Same thing as A. but with the other vehicle.

C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.

D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.

Which phrase describes a density-independent limiting factor that can affect
Alenkasestr [34]

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

<h3>What is a density-independent limiting factor?</h3>

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.
