Answer:
Rivers possess different features as they age. Old rivers usually have a low stream (gentle) gradient and low erosive energy. They usually have broad U shape, the water is usually brown and they have flood plains. Seasonal floods are also common.
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.

Answer:
During the day, plants produce (oxygen) by splitting water molecules in the light-dependent reactions of photosynthesis. At the same time, plants use cellular respiration to produce some of the (carbon dioxide) needed by the light-independent reactions to make sugars. During the night, plants produce (carbon dioxide, but not oxygen) because (only cellular respiration) takes place.
Explanation:
I will try to explain you, why is this the correct answer. During the night, there is only cellular respiration. Let me give you equation to understand the concept better. The equation of cellular respiration is: C₆H₁₂O₆ + 6O₂ + 6H₂O -> 6CO₂ + 12H₂O + ATP (energy) .. During the cellular respiration, the organism is making carbon dioxide, water and energy from glucose and oxygen. The plants are using oxygen during the night and making carbon dioxide.
I hope I helped you. I will be really happy, If you mark my question as brainliest.
