Answer:
They play an important role in the oxygenation of Earth's atmosphere roughly around 2.3 billion years ago.
Explanation:
Weather : too cold or too hot due to climate change
Habitat can be destroyed due to natural phenomenon
Prey cut off by physical barrier
Lack of water
Answer: More carbon dioxide gas would be found in the atmosphere.
Explanation:
The statement which describes the dependent variable would be the measured variable. We usually use the independent variable and manipulate it and change its levels to see how the levels of the measurable (dependent) variable change.
Answer:
The correct option is this: A specific enzyme removes the hydrogen from the monosaccharide and the hydroxide from the polysaccharide, creating a bond between the two and creating a water molecule.
Explanation:
The process by which a monosaccharide molecule is added to an existing polysaccharide in biological systems is called CONDENSATION POLYMERIZATION.
During the process of condensation, an hydrogen atom and an hydroxide molecule from the reactants come together to form a water molecule; this leads to the formation of covalent bond between the reactants.
Condensation reaction is used in living organisms to produce complex macro molecules such as carbohydrates, proteins and lipids, which are needed by the body for health growth.
Remember, condensation reaction always results in loss of water molecules and formation of more complex molecule. One example of monosaccharide is glucose while cellulose (found in plants) and starch (found in animals) are examples of polysaccharides.
