Homework Answers
Answer 1:(B) Rough endoplasmic reticulum. ( As endoplasmic reticulum (ER) is involved in the synthesis of lipids and synthesis and transport of proteins.
Answer 2:(C) Apoptosis ( It is a process of programmed cell death)
Answer 3:(B) Transporters and ATP ( For the active transportation ATP is required.)
Answer 4:(C) Prophase ( It is an initial stage of mitosis where chromatin condense into chromosomes)
