Astudent makes the analogy that the cardiovascular system is like a highway. why is this a good analogy?

The correct answer is that the blood transports materials to and from distinct parts of the body.

Explanation:

As an essential biological fluid, blood flows spontaneously in the blood vessels and the heart, mainly via the pumping of the heart. It comprises plasma, aqueous fluid, and various cells like red blood cells that offer it its color.  

The blood helps in the mediation of nutrients and oxygen, which are essential for performing important procedures of the body. It also assists in translocating molecules and cells of the immune system to various tissues, and to disperse hormones all through the body.  

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
