Answer:
Lipid bilayer
Explanation:
Red blood cell is surrounded by a cell membrane that separates its interior from the surrounding medium. The cell membrane is a lipid bilayer and consists of two layers of phospholipids. The polar heads of phospholipids make the surfaces of the cell membrane while their nonpolar tails are buried in its core.
The snake venom has phospholipase enzymes that digest the phospholipids into fatty acids. Digestion of phospholipids of the lipid bilayer of red blood cells would cause leakage of their content into the surroundings and loss of integrity of cells.
Answer:
c) melatonin
Explanation:
Melatonin its a hormone formed by the pineal gland, which regulates an individual wake cycles and sleep. Jetlag alters the hormone function leading to an alteration with the body clock of the persom.
Jetlag is a sleep disorder common to those who travel swiftly over several time zones. It is not a permanent sleep disorder. Its due to the body's internal clock lacking sync with cues generated in a different time zone, Cues may be due to light exposure and how often the person eats.
A basic factor on ones internal clock is sunlight. It controls the regulation of melatonin which aid in synchronizing cells in the body.
Specific cells of the tissue at retina moves the light signals the thypothalamus.
At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.

Buffer is an aqueous solution that resists changes in pH when acids or
bases are added to it. A buffer solution is typically composed of a weak
acid and its conjugate base. There are three major buffer systems that
are responsible for regulating blood pH: the bicarbonate buffer system,
the phosphate buffer system, and the plasma protein buffer system. Of
the three buffer systems, the bicarbonate buffer system is arguably the
most important as it is the only one that is coupled to the respiratory
system
