Answer:
Both statements are true
Explanation:
Many small tree saplings are competing for sunlight on the forest floor because tree saplings in forest floors are often deprived of adequate light as a result of the shade created by bigger trees in the forest. <em>Hence, the saplings jostle for light in order to effectively carry out light-requiring physiological activities such as photosynthesis and chlorophyll synthesis.</em>
The West Nile virus a virus that <em>generally affects the central nervous systems of birds - the primary host. It is transmitted from one bird to another through contact and by a vector - the mosquito</em>. The virus is also capable of being contracted by humans where it causes fatal neurological disorders.
Only pertain to exchanges and interactions that occur within the atmosphere.
Answer:
The answer is d. pyruvate
Explanation:
An oxidizing agent is the substance that gains electrons in a chemical reaction. At the end of the reaction it is reduced and its oxidation state increased.
A reducing agent is the substance that loses electrons in a chemical reaction. At the end of the reaction it is oxidized and its oxidation state decreased.
Pyruvate gains one electron, it is reduced from pyruvate to lactate; thus, pyruvate is the oxidizing agent.
NADH loses one electron, it is oxidized from NADH to NAD; thus, NADH is the reducing agent
Answer;
Carbon
Explanation;
-The large diversity of shapes of biological molecules is possible because of the extensive presence of carbon in the molecules.
-The major classes of biological molecules that are important for all living things are carbohydrates, lipids, proteins, and nucleic acids. These molecules differ in structure and function, in part, because of different functional groups.
All organic molecules contain carbon atoms. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.
-Carbon qualifies as the foundation element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
