Brums [2.3K]

Answer:

The animal cells produce the collagen but the plant cell does not produce collagen that responsible for producing the complex structure of protein and carbohydrates that is called extracellular matrix cell. Collagen is an important protein that provides strength to the structural integrity. On the other hand, the plant has not collagen so they have their extracellular supportive structure.

What would happen to the oceans if continental and oceanic crust had the same density?
levacccp [35]

Answer:

The oceanic crust is formed by partial melting of the mantle at mid-ocean ridges. The continental crust is formed even more cycles of partial melting over time, resulting less dense rocks.

Explanation:

The mantle, oceanic crust, and continental crust all have different compositions due to a process called partial melting.

This is where you start to melt a rock, but don´t melt it all the way.

When you partially melt a rock, certain chemical elements tend to stay in the solid rock while others tend to go into the melted part.

As a result, the rock that forms from that melt is less dense than the original rock.

If you then partially melt that rock, you get a rock that is even lighter.
