Answer:

D

Explanation:

Evolutionary biologists have been investigating the possibility that some evolutionary changes occur in a clock-like fashion. Over a long period of time, mutations may build up in any given stretch of DNA. The Molecular Clock is a way of interpreting random genetic mutations in every living creature and deduce from them it’s evolutionary past.

Molecular clock helps us tell time on an evolutionary scale. It measures the number of changes in a genome over time. These changes or mutations between two species accumulate over time. The molecular clock allows us to see both how individual species evolve as well as when species branch off from each other evolutionarily.

The liver and muscles store enough glycogen to last _____ hours
Zigmanuir [339]
I think the answer would be around 6-24 hours

Glycogen will be broken down into glucose that becomes the main supply of energy around 2 hours after eating(postprandial) period. The effect should be declined after 12 hours, which is why fasting glucose is taken around that time. After the glycogen depleted, the blood sugar will keep become lower and the body will start making glucose using protein or lipid.
