Explanation:
Answer:
A
Explanation:
Golgi apparatus, a membrane-bound organelle with cisternae, delivers proteins and lipids from the endoplasmic reticulum to where they are needed- such as for secretion outside the cell. Fused vesicles with proteins/lipids that pinch off from the <em>trans</em> end of the ER fuse with the <em>cis</em> end of the Golgi apparatus delivering the ‘cargo’. The proteins/lipids are then given post-translation modified and ‘marked’ for different deliveries. At the trans end of the Golgi apparatus, the vesicles pinch-off with the modified proteins and transported to their destination.
Answer:
C. Cholesterol
Explanation:
Cholesterol maintains the fluidity of the cell membrane and thereby, regulates its function.
Bile acids are derived from cholesterol which serves as their precursor. For example, Taurocholic acid is a polar derivative of cholesterol. Bile acids serve in the absorption of fatty acids, glycerol, and fat-soluble vitamins as these compounds are non-polar in nature.
Vitamin D is produced when the derivative of cholesterol, 7-dehydrocholesterol undergoes photolysis in skin cells in presence of sunlight.
Biosphere, Geosphere (maybe cryosphere), hydrosphere.
I'm not sure, correct me if I'm wrong.
This process is called melting. When a solid melts, it turns into a liquid.
