the centromere
A reduction reaction involves? - ANSWER-the gain of electrons
ABO blood type is a good example of? - ANSWER-multiple alleles
Aerobic respiration - ANSWER-Respiration that requires oxygen
Alleles - ANSWER-alternative versions of a gene
An oxidation reaction involves? - ANSWER-the loss of electrons
Anaerobic respiration - ANSWER-Respiration that does not require oxygen
Anaphase - ANSWER-the third phase of mitosis, during which the chromosome pairs
separate and move toward opposite poles
ATP synthesized without oxygen by fermentation is also called? - ANSWER-anaerobic
respiration
C3 Photosynthesis - ANSWER-The most common form of photosynthesis- a one-stage
process in which atmospheric CO2 is used to form 3-phosphoglycerate, a three-carbon
sugar
C4 photosynthesis - ANSWER-The two-stage photosynthetic pathway in which CO2 is
first fixed in mesophyll cells to form 4-carbon acids, and then the 4-carbon acids are
broken down into 3-carbon acids in the bundle sheath cells
Cancer - ANSWER-an error in the cell cycle in which a cell gets past a checkpoint and
divides uncontrollably, forming a tumor
Carbon Dioxide enters plants through? - ANSWER-pores in the leaf called stomata
Carbon dioxide is fixed during? - ANSWER-The Calvin Cycle
Cell division consists of? - ANSWER-mitosis (division of the nucleus) and cytokinesis

Diploid cells - ANSWER-A cell containing two sets of 23 chromosomes (2n), one set
inherited from each parent.
DNA does not replicate again before? - ANSWER-meiosis II
DNA molecules are combined with proteins to form? - ANSWER-chromatin, the

DNA replicates when? - ANSWER-before cell division (mitosis) during the S or
synthesis phase of interphase
dominant - ANSWER-Describes a trait that covers over, or dominates, another form of
that trait.
During anaphase I in meiosis, what happens? - ANSWER-the sister chromatids move
together to the same pole
During anaphase II in meiosis, what happens? - ANSWER-the sister chromatids are
separated to opposite poles
During anaphase in mitosis, what happens? - ANSWER-the sister chromatids are
separated to opposite poles
Equation for Photosynthesis - ANSWER-6H2O + 6CO2 + light energy --> C6H12O6 +
6O2
Equation for Photosynthesis in Words - ANSWER-water + carbon Dioxide + light energy
--> glucose + oxygen
Examples of C4 plants - ANSWER-sugarcane and corn
