Answer:
Pancreas secrets two hormones called insulin and glucagon which helps in maintaining the glucose level in the blood.
Explanation:
Pancreas secrets a hormone called as insulin, which helps the cell in absorbing the glucose by reducing the blood sugar and providing glucose for energy. On falling of the sugar level pancreas releases a hormone called glucagon. This glucagon informs the pancreas about the presence of low sugar in blood, after which it releases the stored glucose, and helps in raising the blood sugar level. Alpha cell of pancreas produces glucagon.
An absorptive heterotroph is an organism which secretes enzymes externally into its environment to digest organic materials which are then absorbed.
Due to a law being a predicted sort of event that is bound to happen every time, a pattern, we can say that since the cell theory is a pattern instead of a possible explanation, it can be a law. However, since we don't have an accurate explanation to the part which claims that they all come from pre-existing cells, it is a theory, we don't have enough information to confirm that the theory is a solid fact, therefore, we can't confirm that it is a law.
