<span>Organisms that can produce their own nutrients are called autotrophs, while the organisms that cannot produce their own food are called heterotrophs. Heterotrophs obtain the materials from the food they eat while autotrophs make their own nutrients. Hope this answers the question.</span>
Answer:
A) parietal cells
Explanation:
Parietal cells are the epithelial cells of the stomach that have the function to secrete hydrochloric acid (HCl) and intrinsic factor. Parietal cells contain canaliculi – secretory network for the secretion of HCl via active transport.
Parietal cells are regulated via several factors such as acetylcholine, gastrin and histamine. So, if histamine receptors are blocked via antacid drugs , the secretion of the acid will be reduced.
It will probably take the highest roll in the food chain which then factors to the other animals either dying, or competing for resources. making the ecosystem unstable.
Answer:
I) Presence of nuclear envelope
II) Presence of membrane-bounded organelles
Explanation:
Unlike prokaryotic cells, eukaryotic cells possesses nuclear membrane and membrane-bound organelles. As a result, they undergo mitosis and meiosis.
Examples of organisms with Prokaryotic cell are bacteria, cyanobacteria
Examples of organisms with eukaryotic cells are green plants, fruitfly etc
