ACHS NAT 501 A & P 1 EXAM STUDY
SET A+ GRADED
Which of the following lists illustrates the idea of increasing levels of organization? -
ANSWER Molecules, cells, tissues, organs, organ systems
The temperature in a room drops to 65oF, causing the heater to turn on. The
temperature change is an example of a(an): - ANSWER stimulus
What is the name of the membrane on the surface of the lung? - ANSWER Visceral
pleura
Water, or H2O, is an example of which level of organization? - ANSWER Molecule
The ability of an organism to sense changes in its body is an example of: - ANSWER
responsiveness
What type of chemical bond is formed when ions with opposite charges are attracted to
one another? - ANSWER Ionic bond
Within a phospholipid molecule, what is true about the properties of the phosphate
"head" and the fatty acid "tails"? - ANSWER Phosphate is hydrophilic and the fatty acids
are hydrophobic
An atom of oxygen has an atomic number of 8. Its isotope with a mass number of 15
would have how many neutrons in its nucleus? - ANSWER 7
How would the addition of lactic acid to a solution change the pH of the solution? -
ANSWER Decrease the pH
Atoms that lose or gain electrons become electrically charged particles called: -
ANSWER ions
What occurs when telomeres shorten to a certain length? - ANSWER The cell stops
dividing
What is the process called by which glucose can pass through a membrane using
special carrier proteins? - ANSWER Facilitated transport
Glucose is a polar molecule that requires a carrier protein in order to diffuse through
the plasma membrane's nonpolar barrier. In this scenario, what type of cellular
transport does glucose utilize? - ANSWER Facilitated diffusion
How can nerve cells and muscle cells differ in structure and function but come from the
same original cell? - ANSWER Each cell expresses a different subset of genes
