a vasoconstriction.
b vasodilation.
c shivering.
d sleeping.
e all of these.
question 2

a cells, tissues, organs, organ systems.
b tissues, cells, organs, organ systems.
c organs, organ systems, tissues, cells
d organ systems, cells, organs, tissues
e cells, organs, tissues, organ systems

Explanation:

Question 1: Shivering is an involuntary muscle contraction that generates heat to maintain body temperature. Vasoconstriction reduces heat loss (not generates heat), vasodilation increases heat loss, and sleeping does not generate heat.
Question 2: The human body’s organizational levels progress from the simplest unit (cells) to tissues (groups of cells), organs (groups of tissues), and organ systems (groups of organs).

Answer:

Question 1: C. shivering.
Question 2: A. cells, tissues, organs, organ systems.
