When neurons "fire," the first thing that happens is that sodium ions enter the cell. this does not require an input of energy.
Karo-lina-s [1.5K]

Answer;

One can infer that membrane transport proteins are required in order for neurons to fire.

Explanation;

Transport proteins are proteins that transport substances across biological membranes. Transport proteins are found within the membrane itself, where they form a channel, or a carrying mechanism, to allow their substrate to pass from one side to the other.

-Transport proteins transport materials such as; ions such as sodium and potassium; sugars such as glucose; proteins and messenger molecules; and many more. In neurons, they  play a fundamental role in the functioning of nerve cells. These transporters, a third class of membrane transport proteins, move a wide variety of ions and molecules across cell membranes.

A species of moth has a 2 varieties of wing color: brown and white. As winter approaches, the trees where the moths live loose t
Morgarella [4.7K]

Assuming that this question makes reference to the survivability of the two moth variations, we can confirm that the brown-colored moth will be better adapted to survive in the winter months.

<h3>Why are the brown moths more likely to survive?</h3>

This has to do with their ability to better hide from predators. As described in the question, their primary predator are birds that hunt them while resting on the tree bark. This means that the white-colored moths will stand out against the dark tree bark and be easier prey for the birds. This will eventually lead to all the moths in the area being brown-colored through the process of natural selection.  

Therefore, we can confirm that the brown-colored moth will be better adapted to survive in the winter months due to their ability to hide from predators.
