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.
Answer:
primary succession takes longer

Answer:
lysosomes
Explanation:
Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.
