Answer:
A. Phospholipid bilayer
Explanation:
Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.
The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.
Answer:
Energy carriers may be broken apart in order to power an endergonic reaction or be assembled using energy from an exergonic reaction.
Answer:
The human skull consists of 22 bones (or 29, including the inner ear bones and hyoid bone) which are mostly connected together by ossified joints, so called sutures. The skull is divided into the braincase (neurocranium) and the facial skeleton (viscerocranium). Its main task is the protection of the most important organ in the human body: the brain.
The brain is almost entirely enclosed by the neurocranium with the exception of the foramen magnum and other foramina at the skull base which serve as entry and exit point for blood vessels and cranial nerves. Also, the skull provides support for all of the facial structures.
<span>It is true that AIDS is classified as a chronic disease, as the AIDS- related illnesses are not the primary threat, since the patients have access to treatment, but the complications resulting in a chronic disease.</span>
to make ATP, H+ ions will flow through the ATP synthase. this movement through ATP synthase will create enough energy for ATP to be formed.
