Answer:
<u>III → IV → II → I → V</u>
Explanation:
The first response would be binding of antigenic determinants from pathogen to the receptors on lymphocytes then lymphocytes would become active and they increase their quantity followed by secreting antibodies that will eventually destroy the pathogen. Memory cells will recognize this pathogen as foreign body and they will always remember it.
The correct answer is this: THEY WILL BREAK DOWN.
In chemistry, entropy is defined as the degree of disorderliness or randomness of a system. Entropy has to do with the second law of thermodynamic, which relates to how energy spread out. The entropy of a system can be positive or negative depending on the direction of flow of energy. In positive entropy, the degree of disorderliness increases while in negative entropy the degree of randomness decreases. A positive entropy will always leads to the breakdown of the affected molecules.
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.
