Question

cessary conditions for autotrophic nutrition and what are its by-
products?
8. What are the differences between aerobic and anaerobic respiration? Name some
organisms that use the anaerobic mode of respiration.
How are the alveoli designed
9.​

Answer 1

Explanation:

8.Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created

7.Autotrophic nutrition takes place through the process of photosynthesis. Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.

9.The alveoli are thin-walled and richly supplied with a network of blood vessels to facilitate the exchange of gases between blood and the air-filled in alveoli. They have a balloon-like structure that provides maximum surface area for exchange of gases.
