Pearson Final Actual Exam questions
and answers
The neurons responsible for hearing, language, memory, and emotions can be found in
the __________ lobe. - Answer-temporal
The midbrain, pons, and medulla oblongata are all part of the __________. - Answer-
brainstem
Which of the following is NOT a function of cerebrospinal fluid (CSF)? - Answer-
maintain high intracranial pressur
While observing a cross section of the spinal cord under the microscope, you notice a
butterfly-shaped area on the inside. You would identify this as the __________. -
Answer-gray matter
Neurons that carry signals from the CNS to skeletal muscles are part of the
__________. - Answer-somatic motor division
A plexus is a __________. - Answer-network of spinal nerves
Neurons that relay information within the CNS and are the location of information
processing are called __________. - Answer-interneurons
Homogeneous mixture - Answer-- can't see individual parts
- well blended mixture
- [solution]
- ex. ocean water
Heterogeneous mixture - Answer-- you can see individual parts
- not thoroughly mixed
- ex. salad
solute - Answer-- substance that is present in the smaller amount
- is dissolved by the solvent
- can be solid, liquid, or gas
- can raise/lower freezing/boiling point
- In salt water, it is the salt
solvent - Answer-- substance that is present in the largest amount
- dissolves the solute
- can be liquid, gas, or solid
- is often water
- when it is in the solid state, the solute also has to be solid
, - In salt water, it is the water
solution - Answer-- a well mixed mixture
- contains a solvent and at least one solute
- homogeneous mixture
Distillation - Answer-- boiling a liquid solution
- the water will boil away, leaving only the solute.
How can you tell which solution is more concentrated by distillation? - Answer-If you
have two solutions with the same volume and you distill it, all the solvent will boil away
and you will be left with just the solute. Whichever solution has more solute is more
concentrated
suspension - Answer-- mixture
- particles can be seen easily
- particles can be separated by filtration
colloid - Answer-- mixture
- small particles that do not dissolve
- particles do not settle
- has Tyndall effect
Tyndall effect - Answer-where the particles in a colloid scatter a light beam
Dilute solution - Answer-A mixture that has very little solute dissolved in a certain
amount of solvent
Concentrated solution - Answer-A mixture that has a lot of solute dissolved in a certain
amount of solvent
Solubility - Answer-A measure of how much solute can dissolve in a solvent at a given
temperature
Saturated solution - Answer-When you've added so much solute I the solvent that
nothing else dissolves
Unsaturated solution - Answer-If you can continue to dissolve more solute, you have a
________.
You're gonna do great on this exam, I know it! (thanks) - Answer-thanks
Supersaturated solution - Answer-A type of solution that has more dissolved solute than
is predicted by its solubility at the given temperature
