Biology EOC QUESTIONS AND CORRECT
ANSWERS RATED FOR GRADE A+ FOR
ACADEMIC YEAR2025-2026
10% Rule --------correct answer------90% of energy is lost to the environment (through heat), only 10% of
the energy is transferred to the next trophic level
Abiotic --------correct answer------Non-living factors in an environment
Acid Rain --------correct answer------A result of industrial pollution, caused by the burning of fossil fuels
Activation Energy --------correct answer------amount of energy needed to start a reaction
Active Transport --------correct answer------Requires energy (ATP) for large molecules. Gets molecules
across the cell through pumps and vesicles (endocytosis and exocytosis)
Aerobic Respiration --------correct answer------Stage of Cellular Respiration that requires Energy; includes
the Krebs Cycle and ETC
Alcohol Fermentation --------correct answer------In Anaerobic Respiration- occurs mostly in yeast,
pyruvates break down forming alcohol, CO2, and releasing energy
Alleles --------correct answer------different forms of a gene (Ex. 'A')
Amino Acid --------correct answer------Bounded by peptide bonds; monomer of a protein
Anaerobic Respiration --------correct answer------Doesn't require oxygen; includes Lactic Acid
Fermentation and Alcohol Fermentation of Cellular Respiration
, Analogous Structures --------correct answer------Similar in appearance and function but have different
evolutionary origins
Anaphase --------correct answer------Spindle fibers pull the sister chromatids apart, pulling them away
from the center of the cell
Anatomy --------correct answer------The study of the structures of organisms
Anticodon --------correct answer------3 base complement to the codon on the tRNA
Asexual Reproduction --------correct answer------Involves one parent through Binary Fission and Mitosis
resulting in offspring that is identical to the parent with no genetic variability
ATP --------correct answer------Main source of energy for the cell; made in the Mitochondria. When used
in the cell it turns into ADP and returns to the Mitochondria to be converted back
Biotic --------correct answer------Living factors in an environment
Cancer --------correct answer------Uncontrolled Cell Growth (tumor)
Carbohydrate --------correct answer------(monosaccharides) main source of energy for the cell; 1 gram = 4
calories
Carbon Cycle --------correct answer------Major element of living things, found in the atmosphere. Plants
use CO2 to produce glucose. Heterotrophs then consume the plant and create CO2 through cellular
respiration.
Carnivore --------correct answer------Eat primarily consumers (meat)
Carrying Capacity --------correct answer------Maximum population size that can be supported by the
resources available
