There are two primary models of the universe. One is the expanding model, which says that the universe is Constantly increasing in size. The other is, the steady state model, which says that the universe is approximately Constant in size and shape. What evidence would you expect to see if the expanding model were correct?

One is the expanding model, which says that the universe is Constantly increasing in size.

Explanation:

I believe its that

In a short way, if an object is moving away, the light that comes from that object will have a red shift (it seems a little more reddish than it actually is)

If the object is moving towards us, the light that comes from the object will have a blue shift (it seems a little more blueish than it actually is)

Those shifts can be observed from the Earth, so from that is safe to conclude that the expanding model is actually correct.

Explanation:

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

answer; both surfaces of the membrane are nonpermeable
