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.

The answer is:
Total used energy is the energy released by the hydrolysis of one mole of ATP and it is 30.7 kJ.
Total possible energy (used pus released as a heat) is 2870 kJ.
So, we calculate total used/total possible=30.7/2870=0.01069 or 0.017. Expressed in percentage: 1.07% energy is used.
Answer:
Convergent Evolution
Explanation:
Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.
An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.
Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate
.
