Empirical evidence is obtained using our human senses, which statement
Inessa05 [86]

Explanation:

There are all kinds of evidence used in science, but empirical evidence is obtained as a result of <u>repeated experiments and observations</u>. This evidence is used to either support or argue against a scientific theory. Empirical evidence is the preferred evidence since this kind of evidence can be peer reviewed, i.e. reviewed by other scientists and/or researchers. In other words, the experiment can be redone, and the <u>evidence can be tested</u>.

Which one of the following is a major difference between the circulatory systems of earthworms and fish?
labwork [276]
<span>a. Fish have a single central heart; earthworms have several hearts.

</span>
Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and  metabolic waste taken away  in a  continuous, never ending  process.
<span>A mechanism  is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this  bill splendidly. It is a specialized organ system which allows blood  and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs  to be expelled from the body.
