Answer:
Can you provide more details please?
Explanation:
Water at 4 degrees centigrade has the highest density of all other water temperatures. This is why ice (whose temperature is below 0 degrees) floats on very cold water. This phenomenon is significant in the Artic and Antarctic where ice shelves float on cold ocean waters in the poles. Animals that live in these regions (such as seals and polar bears) use these ice shelves as hunting platforms.
Thank you! you as well buddy!
THE STRUCTURE OF THE CELL MEMBRANE
the cell membrane is a thin layer of a partially permable membrane. That protects the cell's organelles and helps to maintain the shape of the cell.
WHAT MATERIALS ENTER OR LEAVE THE CELL MEMBRANE.
since the cell membrane is partially permable, that it only allows some materials to pass through it only nutrients that need to be metabolized or neede by the cell is allowed or permitted to go in the cell either by diffusion or osmosis.
HOW IE ONE METHOD DIFFRENT FROM THE OTHER?
since diffrent materials that go in the cell have different concentrations, sizes, and weights, the method by which they go into the cell will definately be diffrent materials with larger molecules use the osmosis method to go in the cell, while materials with smaller molecules use the diffusion method. I HOPE THIS REALLY HELPED
Answer:
A. The magma cooled too quickly too quickly for gas to escape.
Explanation:
Scoria is a type of extrusive igneous rock. Some of their characteristics include that they cool quickly with no time for large crystals to form, some of them have large vesicles which are holes caused by gas bubbles when the lava was molten.
