BIO100 Exam 1 UWL Questions and Answers
Question 1.
plasma membrane
Correct Answer: -an outer covering that separates the cell's interior from its
surrounding environment -selectively permeable -outside hydrophilic and inside
hydrophobic -flexible -phospholipid bilayer -phospholipids, cholesterol, proteins,
carbs
Question 2.
hypertonic
Correct Answer: greater solute concentration
Question 3.
sense and respond to stimuli
Correct Answer: -behavior/reacting to the environment -response to diverse
stimuli -ex: sunflower turns toward sun
Question 4.
cytoplasm
Correct Answer: consisting of a jelly like region within the cell in which other
cellular components are found
Question 5.
nucleic acid monomer
Correct Answer: nucleotide
Question 6.
electron characteristics
Correct Answer: -negative charge (-1) -no mass -located in space around nucleus
-creates ions
Question 7.
outside cell concentration
Correct Answer: -equal amount of water and sugar -water to sugar ratio 1:1 -the
solution outside the cell will become less concentrated with the net movement
of water
Question 8.
Scientific Method
Correct Answer: -testing and hypothesis logical problem-solving method
-scientific theory -scientific laws
Question 9.
protein variable group
Correct Answer: "R" which determines the difference in protein properties
(anything extended beyond the common group)
, Question 10.
reproduction
Correct Answer: -producing new organisms -DNA replicated and genes passed to
offspring
Question 11.
factors that effect rate of diffusion
Correct Answer: distance, temp, characteristics of solvent, characteristics of
substance traveling, and characteristics of barrier
Question 12.
carb function
Correct Answer: short term energy
Question 13.
matched variables
Correct Answer: made the same between controls and experimental groups
Question 14.
subatomic particles
Correct Answer: proton, neutron, electron
Question 15.
simple diffusion (passive transport)
Correct Answer: -material moves across membrane from high to low
concentration (no added energy) -nonpolar molecules
Question 16.
net charge
Correct Answer: -The sum of negative (electrons) and positive (protons) charges
-atom with charge = ion
Question 17.
