Answer: Basic Principles of Gas Exchange
Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.
Explanation:
Gas Exchange with Tissues
Gas exchange occurs in the alveoli so that oxygen is loaded into the bloodstream and carbon dioxide is unloaded from the bloodstream. ... Oxygen diffuses into the cells of the tissues, while carbon dioxide diffuses out of the cells of the tissues and into the bloodstream.

Answer:
True
Explanation:
Carbohydrates products primarily glucose, galactose and fructose are absorbed in the small intestine. The apical membrane with in the small intestine absorbs Glucose and galactose while fructose is absorbed through facilitated diffusion via GLUT5
However, amino acids are absorbed by Sodium cotransporter. Sodium cotransporter is found in the intestinal mucosa of small intestine and then transported via facilitated diffusion across the basolateral membrane
Hence, the given statement is true
<span>Scavengers play an important role in the ecosystem by contributing to the decomposition of dead animal remains. Decomposers complete this process, by consuming the remains left by scavengers. So here there's your answer :)</span>
