Answer:
Energy supply
Explanation:
Nutrition, which is the ability to obtain food, is one of the characteristics of living organisms. However, the food ingested by organisms serve series of purposes in their system. These functions include maintaining biomass (total weight), and waste production as mentioned in the question.
In addition to this, one important role food ingestion plays in living organism is the SUPPLY OF ENERGY. Food ingested is broken down into smaller units, which is then used by the cells to synthesize energy in form of ATP. This process in living organisms is called RESPIRATION.
The energy (ATP) is used to power various cellular functions undergone by the organism.
Answer:
A semipermeable membrane is a barrier that will only allow some molecules to pass through while blocking the passage of other molecules. A semipermeable barrier essentially acts as a filter. Different types of semipermeable membranes can block out different sized molecules. A semipermeable membrane can be made out of biological or synthetic material.
Explanation:
Gastropods are centrally flattened molluscs that move via muscle contractions.
<h3>What are gastropods?</h3>
