Answer:
the molecules at the surface are being pulled by other molecules. The pulling forces the water to curve. ... The positive hydrogen ends of one water molecule attract the negative oxygen ends of nearby water molecule.
Explanation:
First let me say this, i may be wrong. I think it would change over time because first of all the sandstone has different densities. Different kinds off rocks erode and get broken down by the wind at different rates. If its density is higher, it will take longer to erode
A stands out most to me, CO comes from the air and air is basically oxygen we breath. When we exhale CO comes out (of course). I would say A is correct.
Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
