Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation
Soloha48 [4]

Answer:

The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.

Explanation:

In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.

Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

Most fertilizers contain ammonia. Ammonia (NH3) forms when hydrogen reacts with nitrogen. Which balanced equation represents amm
Lana71 [14]
<span>The balanced equation for ammonia (NH3) is 3H2 + N2 ď 2NH3. This equation starts from H2 + N2 ď NH3. We have 1 N and 3 H on the right side (the product side) of the equation, so we multiply each by 2 to get 2 N and 6 H. We do this so that we don’t have an odd number of H atoms. We then balance the left side (the reactant side) of the equation with the right side, N is already balanced, but we have to multiply H by 3 to get 6 H atoms (to match the right side of the equation.</span>
