Because people and animals exhale carbon dioxide which plants need and they release oxygen
Answer:The Nematoda, similar to most other animal phyla, are triploblastic, possessing an embryonic mesoderm that is sandwiched between the ectoderm and endoderm. They are also bilaterally symmetrical: a longitudinal section will divide them into right and left sides that are symmetrical.
Explanation:
Okay some evidence that supports this is that they continents seem to fit together like puzzle pieces. Which is the theory of continental drift. The continents all together they call it pangea. So more detailed empirical evidence is that fossils being found in areas of several continents which leads us to believe it was one big land mass. Climate change and glaciers are another indicator. The rock/mountain types that tend to match indicating they were once connected. Coal fields also show there could have been one big coal field but was broken due to the continental drift theory
Answer:
Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm
Explanation:
A food vacuole is a membrane-enclosed sac in a cell which is formed by the ingestion of the food particle from the outside environment through the process of phagocytosis.
The formation of food vacuole is a feature of the protozoa like amoeba which engulfs its food.
The food vacuole then fuses with the lysosome present in the cell which contains the digestive enzyme and then forms phagolysosomes which can digest the food particles in an enclosed sac.
Thus, the selected option is the correct answer.
