Scientists develop knowledge by making OBSERVATION about the natural world that may lead to a scientific question.
Scientists typically use scientific methods to make observations from the natural world, from these observations they develop hypothesis which are used as a road map for the conduct of their experiments.
Answer:
A single phosphate
Explanation:
A phospholipid is a fatty acid compound which is hydrophobic in nature due to which it forms the cell membrane of a cell.
The phospholipid is composed of a phosphate group, fatty acid chains, and glycerol molecules.
The glycerol molecule attached to a phosphate group forms the head of the phospholipid and the fatty acid forms the tail of the phospholipid. The head is the hydrophilic portion of the lipid while the tail is the hydrophobic portion of the phospholipid.
Thus, a single phosphate is correct
If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.
Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.
In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).
