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.

Tsunami El Nino storm and a small asteoid would cause short term environmental change.

Short term environmental change can be defined as a rapid shift in the environment that has an instantaneous impact on organisms (causing behavioral adaptations).  

The terrain is altered by a tsunami. It disrupts wildlife habitats, including bird nesting grounds, by uprooting trees and plants.  

El Nino is the tropical Pacific region's strongest weather pattern change. It results in violent storms,  famine, fish kills, coral bleaching, and forest dieback.

A significant amount of dust would be released into the atmosphere if the asteroid hit land. There would be a surge in water vapor in the atmosphere if it hit in water. As a result, there would be more rain, which would cause mudslides and landslides.

<span>"All organisms have the same proteins. 

Proteins are composed of amino acids.
</span>The four bases in DNA are adenine, cytosine, guanine, and thymine.

These four are divided into two groups. The pyrimidines, the single-ring nitrogenous bases, is where thymine and cytosine is included. The purines, the double-ring nitrogenous bases, includes adenine and guanine. 

<span>Cytosine will only bond with guanine; they form three hydrogen bonds. Adenine will only bond with thymine forming two hydrogen bonds."
