Answer:
A) A decrease in Na+ permeability, and an increase in K+ permeability.
Explanation:
When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell K+ permeability while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels so as to restore the charge valance, that means that there is an increase in K+ permeability.
Answer:
Vultures, Hyenas, Ants, Bacteria that's all i got really
Explanation:
All of these either eat remains or break down remains of a decomposing animal and in doing so, speed up the process of the decomposing.
Answer:
The invention of the electron microscope allowed them to see organelles and other structures smaller than cells. There is variation in cells, but all cells have a plasma membrane, cytoplasm, ribosomes, and DNA. These similarities show that all life on Earth has a common ancestor in the distant past
Answer:
It is B, Chloroplasts use carbon dioxide and water to create glucose.
Explanation:
I just had this question and got it right somehow, so there is the answer that was right for me.
Your answer is hypothesis i think. There were no given answer choices so i went with what i think youre asking.
