Which best describes your ability to use a number line to graph order and compare real numbers
The feature that allows this to happen is a semipermeable membrane (selectively permeable membrane). This allows the cell to decide what gets in, it allows things like hydrocarbons and oxygen and water to pass, but prevents large sugars from getting in. The process of water passing through the holes in osmosis which is the diffusion of water across this semipermeable membrane.
DNA is pretty much a blueprint for how cells should work. So DNA tells the ribosomes in the cell to make protein.
Sorry if this answer is incorrect, I'm just starting to learn about this :(
Answer:
The formation of sedimentary rocks is indeed a physical change because we are only changing the physical structure of the rock/rocks by compacting them together, they're still rocks.
Explanation:
Remember that physical changes are when you are only changing a physical characteristic of an object. A common example of a physical change would be breaking a piece of wood. Even though the wood is now smaller, and its physical appearance has changed, the wood is still wood.
Sedimentary rocks are formed by compaction, where many rocks are compacted together, and the pressure causes all the rocks to form together into one big rock.
Sedimentary rocks are formed by many different rocks, which means they are still rocks, but they are now compacted together to form one bigger rock. "The formation of sedimentary rocks is indeed a physical change because we are only changing the physical structure of the rock/rocks by compacting them together, they're still rocks."
Hope this helps.
