Out of the following given choices;

a. they increase the amount of energy transferred from the lungs to the blood

b. they increase the flexibility of the lungs as they expand during inhalation

c. they increase the volume of the lungs, allowing more oxygen to be inhaled

d. they increase the surface area of the lungs, allowing the efficient gas exchange

The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange. Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.

PtichkaEL [24]

One reason biodiversity is such an important aspect of sustainability is that it provides vital ecosystem services through the interactions among species and keeps any population from growing too large (option A).

<h3>What is biodiversity?</h3>

Biodiversity refers to the number and variety of species of plant and animal life within a region.

Sustainability is the means of configuring civilization and human activity so that society, its members and its economies are able to meet their needs and express their greatest potential in the present without compromising the ability of future generations to do the same.

Biodiversity helps to ensure sustainability because it provides vital ecosystem services through the interactions among species and keeps any population from growing too large.

Whereas superficial flexors in the anterior compartment of the forearm originate from the _____ epicondyle of the humerus, the s
ASHA 777 [7]

Answer:

Whereas superficial flexors in the anterior compartment of the forearm originate from the medial epicondyle of the humerus, the superficial extensors in the posterior compartment of the forearm originate from the lateral epicondyle of the humerus.

Explanation:

The forearm has 2 compartments: an anterior compartment responsible for the flexion of the wrist, and a posterior compartment with the function to extend the wrist.

The superficial muscles in the anterior compartment arise from the common flexor tendon that originates from the medial epicondyle of the humerus. This compartment is mostly innervated by the median nerve.

The superficial muscles in the posterior compartment originate from the lateral epicondyle of the humerus and are innervated by the radial nerve.

The ulnar nerve innervates the flexor carpi ulnaris and flexor digitorum profundus in the forearm.
