The correct answer is: A. minus end; dynein
Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.
Necessary proteins for the vesicle’s movement are motor proteins:
• kinesin which is positive end directed
• dynein which is negative end directed
So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
Plants absorb carbon dioxide and water to make their own food and release oxygen
It will completely stop the enzyme's activity when the denaturization is complete.
I believe it is either fish of plants (Most likely plants).
D) orbit the nucleus like the planets orbit the sun.
this idea was first proposed in the rutherford model:)
