Answer:
The correct answer is: the antibodies' shape.
Explanation:
<u>Antibodies are proteins called immunoglobulins that serve the immune system by responding to a specific antigen and generating the proper counter to fight it. </u>
Each antibody consists of four polypeptides that form a "Y" shaped molecule. The Y shape is given by two heavy chains and two light chains.
<u>The tips of the Y are composed of 110-130 amino acids that vary greatly among other antibodies. This gives the antibody its </u><u>specificity</u><u>.</u>

''The movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants'' is the correct statement.
The above statement is correct because chloroplast is an organelle which moves in the cell through the medium known as cytoplasm. Cytoplasm is a thick fluid that fills every type of cell and organelles are floating as well as suspended in this fluid.
All organelles such as the nucleus, endoplasmic reticulum, chloroplast and mitochondria etc are located in the cytoplasm. The portion of the cytoplasm except the organelles is called cytosol so we can conclude that chloroplast is an organelle which moves within the cell with the help of cytoplasm.
