Answer: a. Aerobic respiration, b. Anaerobic respiration.
Explanation: Oxygen is an essential component for aerobic respiration because it is at the end of the electron transport chain, where it accepts electrons and picks up protons to give out water.
The final acceptor of electrons in the electron transport chain during aerobic respiration is oxygen.
The final electron acceptor in the Anaerobic respiration are inorganic molecules such as sulfates. Inorganic molecules are used rather than Oxygen.
Oxygen
C6H12O6+6O2--->6CO2+6H2O
This is the equation for cellular resipiration this is how organisms use carbon-based molecules(glucose) and make water
Answer:
The total amount of matter on Earth constantly increases.
Explanation:
This is because there are always new things taking birth every second and they have matter in them, so the matter is increasing constantly.
Answer:
Epinephrine
Explanation:
Epinephrine, which is also referred to as adrenaline, is the active sympathetic hormone that is secreted by the medulla of the adrenal glands into the bloodstream to initiate the body’s fight-or-flight response to stress or threat, causing increased blood pressure, sugar metabolism, heart rate, breathe rate, muscle strength as well as sweat. Pete's sighting of a bear as a threat stimulates the sympathetic nervous system to initiate the secretion of epinephrine which brings about the fight-or-flight response of the body to increase alertness of the body.
