I think it would be D a pure substance
Several hours after your last meal, declining blood glucose levels stimulate release of the hormone <u>glucagon</u> , which stimulates glycogenolysis, lipolysis and fat mobilization, and gluconeogenesis.
<h3>How does glucagon stimulate gluconeogenesis?</h3>
The biological process through which glycogen degrades into glucose and glucose-1-phosphate is known as glycogenolysis. Hepatocytes and myocytes both participate in the response. Two important enzymes, glycogen phosphorylase and phosphorylase kinase, control the process.
By increasing the activity of hepatic adipose triglyceride lipase, intrahepatic lipolysis, hepatic acetyl-CoA content, and pyruvate carboxylase flux, as well as increasing mitochondrial fat oxidation, glucagon stimulates hepatic gluconeogenesis. All of these actions are mediated by stimulation of the inositol kinase.

Answer:Carbon is the basic building block to most cells in the body. It helps with cellular respiration by which your body releases energy stored in glucose and the glucose compound is composed of carbon, hydrogen, and oxygen.
450 mya, is where you would find fossils.
Explanation:
The first layer would be newer organismis that haven't quite decayed yet.The second and third layer is where the bones of the dead organasims lie, they havent quite been through the whole process yet, but they are nearly complete just about 100,000 years left.The fourth layers have been through alot, and have been there for many many years we can say abot 100,000,000 years.They are ready to become a fossil fuel.
