Answer:
False
Explanation:
Carbon dioxide is an important greenhouse gas found in the atmosphere. Since the start of the Industrial Revolution, record of the concentration of carbon dioxide in the atmosphere have been said to increase by more than about 45%. Recent records indicate concentration to be highest, of which has been linked to the cause of global warming and climate change.
Human activities such as burning of fossil fuels, bush burning, deforestation have lead to a remarkable increase in the concentration of carbon dioxide in the atmosphere.

Answer:
Microglial cell
Explanation:
The microglial cells are macrophages that are in the central nervous system (brain and spinal cord) protecting it. This cells will phagocytize damaged neurons as when a person has Alzheimer as well as agents that can cause a potential damage to the central nervous system such as the meningitis virus. When the Microglial cells phagocytize they absorb the damaged neuron or antigen and then they destroy it.
Answer:
Respiration is important because it converts food energy into chemical energy.
Explanation:
Answer:
It represents the first stage in the chemical oxidation of glucose by a cell.
Explanation:
Glycolysis is the first stage of oxidation of glucose by the process of cellular respiration. Glycolysis includes the breakdown of one molecule of glucose into two molecules of pyruvate. Substrate level phosphorylation forms net 2 ATP molecules and the redox reactions of glycolysis uses NAD+ as an electron acceptor resulting in the formation of 2 NADH.
Therefore, one molecule of glucose obtains 2 pyruvate molecules, 2ATP and 2 NADH by glycolysis. The fate of pyruvate depends on the availability of oxygen. Citric acid cycle and oxidative phosphorylation are the next two stages of aerobic cellular respiration.
