Explanation:
Glycogen is the storage form of carbohydrates in animals. The major sites of storage are liver and muscle.
Glucagon is a polypeptide hormone, it is secreted by the alpha cells of the pancreas. Low blood glucose causes glucagon secretion. When blood glucose level falls, liver glycogen is broken and help to maintain blood glucose level.
Glucagon stimulates the enzyme glycogen phospholylase which breaks down glycogen into glucose units.
Answer:B, D
Explanation:
When the roller coaster starts flying down the hill, it gains kinetic energy and loses potential energy.
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation.
• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering.
• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances.
• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
<u><em>Answer:</em></u>
<u><em>The correct option is </em></u><u><em>A</em></u>
Explanation:
The main adaptation of desert plants is to minimize water loss through their pores and also through the cell walls on their leaves. So the leaves of many desert plants have a thick covering that is coated with a waxy substance that allows them to seal in and protect what moisture they already have.
