<span>Lactic Acid Fermentation and Alcoholic Fermentation. Lactic Acid fermentation produces lactic acid, and alcoholic fermentation produces alcohol and carbon dioxide.Lactic acid fermentation has 2 ATP. Oxygen is required for the process to occur-Aerobic means. No oxygen is required for the process to occur-Anaerobic means. The ferment sugar which produces ethanol, methanol, and only a little ATP.</span>
Answer:
The sessile and free-floating species like sea anemones and jellyfish exhibits a selective advantage due to the existence of the features like radial symmetry and a diffuse nerve net as it helps in the greater dissemination of sensory compositions on the entire body and also homogenously exposes the organism to the environment present around it for enhanced sensory discernment. It helps the organism in approaching their environment equivalently from all the sides.
