Answer is A.

Archaea requires neither sunlight for photosynthesis as do plants, nor oxygen. Archaea absorbs CO2, N2, or H2S and gives off methane gas as a waste product the same way humans breathe in oxygen and breathe out carbon dioxide. An example is chemosynthetic bacteria by sea drifts. They use chemical energy to produce vital processes to live.

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.

Histamine is a chemical substance released in inflammatory and allergic responses. The histamine H1 receptor on target cells is
grin007 [14]

Answer:

-Histamine binds extracellularly to the H1 receptor.

-When histamine binds to the H1 receptor. the receptor undergoes a conformation change and binds the inactive G protein.

-Once the G protein is active, it binds to the enzyme phospholipase C, activating it.

-Histamine is likely hydrophilic.

When histamine encounters a target cell, it binds extracellularly to the H1 receptor, causing a change in the shape of the receptor. This change in shape allows the G protein to bind to the H1 receptor, causing a GTP molecule to displace a GDP molecule and activating the G protein. The active G protein dissociates from the H1 receptor and binds to the enzyme phospholipase C, activating it. The active phospholipase C triggers a cellular response. The G protein then functions as a GTPase and hydrolyzes the GTP to GDP. The G protein dissociates from the enzyme and is inactive again and ready for reuse.

Which of the following best describes the relationship between the structure of the cell membrane and it's function
Sergeeva-Olga [200]
The cell membrane folds upon itself easily, which facilitates cellular reproduction by mitosis. 

<span>The membrane is a flexible, fluid mosaic and changes shape easily to create holes for substances to move in and out of the cell. </span>

<span>The outer layer of the membrane is hydrophilic, which allows water to flow in and out of the cell easily to eliminate waste. </span>

<span>The proteins that are embedded in the cell membrane act as channels to transport substances in and out of the cell.</span>
