General Biology 115 Exam 1 (New 2026/
2027 Update) Questions & Answers {Grade
A} 100% Correct (Verified Solutions)-
Rutgers
The Scientific Method - Correct answer Observation, Hypothesis, Experiment, Data
Collection, Conclusion, and Retest (if needed)
Electrons (e-) - Correct answer a subatomic particle with a negative charge, move
rapidly, determine how element reacts
What happens when an electron is excited? - Correct answer Moves farther away
from the nucleus, can be used to do work
Electron Shell - Correct answer electron's potential energy
Valence Shell - Correct answer the outermost shell- where the bonds between
electrons form
,CHON - Correct answer the 4 main elements in Biology (Carbon, Hydrogen, Oxygen,
Nitrogen)
Molecule - Correct answer compound with 2 or more atoms
Energy - Correct answer capacity to cause change or perform work
Electronegativity - Correct answer affinity for electrons; tendency of an atom go
attract electrons
In terms of biology, which element has the highest electronegativity? - Correct answer
Oxygen
Covalent Bond - Correct answer sharing of electrons between atoms
Ionic Bond - Correct answer stealing of electron between atoms, Polar, anion and
cation, salts
, Nonpolar Covalent - Correct answer same electronegativity = share e- equally
Polar Covalent - Correct answer <2 difference in electronegativity = share e- unequally
Cation - Correct answer positive ion
Anion - Correct answer negative ion
Hydrogen Bond - Correct answer VERY STRONG dipole-dipole interactions; holds
water together (polarity causes attractions w/ eachother)
Van Der Waals - Correct answer develop because electrons are in constant motion
involves hydrogen bonds and london dispersion forces
What are the emergent properties of water? - Correct answer hydrogen bonds,
cohesive behavior, moderates temperature, expansion upon freezing, versatility as a
solvent
