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.
 
        
             
        
        
        
state the uses of excretory products in plants
Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants. Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration.
Hope this helps :)
 
        
             
        
        
        
The axis of the earth is tilted (ANSWER IS C). The equator is heated more than other areas because the sun's rays hit it directly. 
As you move north or south of the equator, they fall slantingly or obliquely. 
When summer is in the south and vice versa, the heat also changes with the earth's rotation. 
The tropic of Capricorn and the tropic of Cancer alternately get direct sunlight. 
Due to the uneven heating of the earth, wind and ocean currents are created, supporting life.
