Answer:
Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure,and understanding the dynamics of energy transfer in an ecosystem.
Answer:
<u>D:</u><u> </u><u>the crust of the lithosphere that has fractured along plate boundaries and ridges</u>
Explanation:
These fault lines in the lithosphere along plate boundaries and ridges are the causes of natural disasters like earthquakes.
No. Yes phenotypes are important for example those with longer legs can run faster and hence escape predators
But genes also code for unseen proteins
For example, if a disease is introduced those with long legs won't survive but those who have the genes which code for the complimentary antibody have the ability to kill the pathogen and hence survive.
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.
