Which is a limitation of a scientific model?
iren [92.7K]

Answer:

The correct option is<em> D)  Models are not the "real thing" so it will never correctly represent the system in all respects.</em>

Explanation:

Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.

As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.

If the pride is taken over by new individuals what happens to the female ?
Step2247 [10]

Explanation:

Pride is the social community of lions where they grow, mate, reproduce, communicate, hunt etc. When male lions gets control of a new territory or a pride, they most of the times kill the cubs of the pride because they are not biologically related and do not want to waste their energy by ensuring that the cubs genes are passed on.

They don't want to be stepfathers. Female lions also will not be responsive to mating during the time they are feeding, so killing the cubs allows the male lions to reproduce.

Why do volcanoes occur most often near plate tectonics?
dem82 [27]
Diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates. We almost never see these volcanoes, because most of them are located on the sea floor.
