Science isn’t science if it can’t be tested and refuted.

____ is the name given to the accumulation of plaque in artery walls.

arterioclogus

arteriosus

arterionecrosis

atherosclerosis

atherosclerosis
The chemicals that make up plaque include lipids, cholesterol, and other elements. The plaques reduce an artery’s diameter and restrict blood flow, occasionally to the point of stopping it.

What distinguishes a hypothesis from a theory?

A theory is not falsifiable; a hypothesis is falsifiable.

A theory and a hypothesis are different terms for the same thing.

A theory is a fact; a hypothesis is a comprehensive explanation.

A theory is a comprehensive explanation of a phenomenon; a hypothesis is a generalized statement that can be used to generate testable predictions.

A theory is a comprehensive explanation of a phenomenon; a hypothesis is a generalized statement that can be used to generate testable predictions.

In the body, ____ blood arteries serve as the conduits for the exchange of oxygen and carbon dioxide.

capillaries

distributing arteries

venules

arterioles

capillaries
Capillaries are just one cell layer thick, which facilitates the interchange of materials more easily than if the vessels were made of many cell layers.

Describe leukemia.

Cancer of blood cell producing tissue

A low white blood cell count

A low platelet count

A high red blood cell count

Cancer of blood cell producing tissue
White blood cells are produced in great quantities as a result of leukemia. Due to the immaturity of these white blood cells, this both decreases the formation of other blood cell types and weakens immune system performance.
