BIOLOGY 1100 ECU TEST 1 QUESTIONS
AND ANSWERS WITH VERIFIED
SOLUTIONS 100% CORRECT
2nd Law of Thermodynamics - correct answer-
Molecules will naturally move down the concentration
gradient
Acid - correct answer- Pulls in electrons=negative
charge
Active Transport - correct answer- Requires ATP,
drives molecules/proteins up concentration gradients by
changing shape of proteins
Adenosine Triphosphatase - correct answer- A
molecule present in all living cells and acting as an energy
source for metabolic processes
Adenylyl Cyclase/cAMP - correct answer- Stopping
process to cooperate with neighbor
Adhesion - correct answer- An attraction between
molecules of different substances
,Amoeba - correct answer- A type of protist
characterized by great flexibility and the presence of
pseudopodia.
Amphipathic Molecule - correct answer- A molecule
that has both a hydrophilic region and a hydrophobic
region.
Anion - correct answer- Negative charge=element
gains an electron
Anton van Leeuwenhoek - correct answer- First to
observe microorganisms using a microscope of his own
design in 1675. Described them as animalcules-little
animals
Atomic Mass - correct answer- The average mass of
all the isotopes of an element
Atomic Number - correct answer- Number of protons
in nucleus of an atom
, Autocrine Signaling - correct answer- Cells release
signals that affect themselves and nearby target cells
Base - correct answer- Pulls in protons=positive
charge
Bilayer - correct answer- a layer that is two molecules
thick
Cadherins - correct answer- A member of an
important class of cell adhesion molecules that requires
extracellular calcium ions for its function.
Cation - correct answer- Positive charge=element
loses electron
Central Vacuole - correct answer- Lysosome like
organelles in plant cells
Change in Gene Expression - correct answer- During
an individual organisms' lifetime, this is most likely to help
the organism respond properly to changes in its
environment
