Insulin is a hormone that helps regulate blood glucose levels. Insulin is made by pancreatic cells in response to increased glucose levels in the blood after
a meal. Insulin binds to receptors on liver cells and stimulates them to
polymerize glucose to form glycogen. Which of the following physiological
responses will most likely occur if insulin stops being made by pancreatic
cells?

O macromolecule, population, community, ecosystem

Explanation:

Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).
