1. The level of organismal organization that includes two or more tissues that are organized
to perform particular processes is known as:
a. interacting chemicals
b. A cell
c. connective tissues
d. an organ
e. an organism
2. Which of the following is not typically a component of lipid rafts?
a. Cholesterol
b. saturated phospholipid
c. nucleic acids
d. integral protein
e. B & D
3. The image shown here is the apical surface of epithelial tissue. The outline of each cell in
this epithelium is created by a marker that binds selectively to occludin proteins. As you
can see, the _____ junctions of these cells makes it difficult for molecules to squeeze
between adjacent cells, which helps make epithelial tissues selectively permeable.
a. Occluding
b. Desmosome
c. Structural
d. Hemidesmosome
e. Adherens
4. Set Point is the component of a negative feedback process that receives information from
receptors (sensors) and sends instruction to effectors ( if needed). It is important because
without this, the body would not know if the body had deviated from homeostasis
and would not know how to correct the problem
5. Historical Constraint is a limit on the possible solutions to environmental challenges
due to the past course of evolution in a species. It is important because
