Answer: A branched polymer has greater terminal glucose residues in comparison to a unbranched polymer of the same molecular weight resulting in a higher number of terminal glucose residues required to be mobilized when energy is demanded. Enzyme and polymer evolve together to meet the dire need for rapid mobilization.

Explanation:

In comparison to an unbranched polymer, a branched polymer has a more compact and symmetrical molecular conformation with a greater terminal glucose residue. It can be broken down easily when energy is needed. For instance, the branched form of starch, amylopetin, in the small intestine starch is hydrolyzed to form glucose which is converted to biochemical energy and stored for later use.

An insect that has evolved to resemble a plant twig will probably be able to avoid A) parasitism. B) symbiosis. C) predation. D)
bagirrra123 [75]

Answer:

C) predation

Explanation:

Such an insect would serve as a prey to a predator in a prey-predator relationship. Such relationship is a predation.

Predation is an act of feeding in a prey. The preys are weaker and smaller organisms which can easily be overpowered by the bigger predators.

When an insect evolves to resemble a plant twig, it is an evolutionary mimicry. Such organism that evolves must be prey. This presents the prey an evolutionary advantage for it to be evaded by the devouring predator. Mimicry is an evasive tactics.

In parasitism, one organism benefits while the other, the host, suffers from the relationship. Here, the parasite is lives inside the host. A mimicry won't apply here.

How do the respiratory and circulatory systems work together to make gas exchange possible?
horrorfan [7]
Oxygen-poor blood enters the heart through the right atrium. From there blood flows through the tricuspid valve into the right ventricle. When the heart contracts during the diastolic phase, this blood is pumped out through the pulmonary arteries that run toward the lungs. At the lungs, the blood is circulated through a series of progressively smaller arterioles until it flows through capillaries lining the lungs' alveolar sacs. It is here that gas exchange takes place as oxygen is taken up by the blood, and carbon dioxide is released into the waste air.After oxygenation, the fresh blood is circulated back through the bronchial veins and into the pulmonary veins. These run from the lungs and drain into the heart's left atrium. During the systolic phase of the heartbeat, the mitral valve under the left atrium opens and permits blood to pass into the left ventricle. This chamber is heavily muscled and it has the power to pump the oxygen-rich blood out through the aorta and into the rest of the body.
