Answer: b. micelles
Explanation:
Phospholipids are lipids that contain a polar part, which is hydrophilic (i.e. likes water) and a non-polar part, which is hydrophobic (i.e. dislikes water).
When phospholipids are in an aqueous environment they form a structure called micelle, in which <u>the polar heads face the water molecules and surround the non-polar tails which remain on the inside</u>. This way, the polar heads protect the hydrophobic chains from exposure to the aqueous environment.
I've attached an image of a micelle for better understanding of its structure.
2,996 people were killed and more than 6,000 others were wounded during the attacks, moment of silence for all those poor people and their families.
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.
