BIO 163 EXAM 2 REVIEW EXAM QUESTIONS AND ANSWERS
Homeostasis - CORRECT ANSWER✅✅The process by which biological systems maintain stability while
adjusting to conditions that are optimal for survival.
Cell Membrane - CORRECT ANSWER✅✅A biological barrier that separates and protects the interior of
all cells from the external environment.
Mitosis - CORRECT ANSWER✅✅A type of cell division that results in two genetically identical daughter
cells, crucial for growth and repair.
Meiosis - CORRECT ANSWER✅✅A specialized form of cell division that reduces the chromosome
number by half, producing gametes for sexual reproduction.
Photosynthesis - CORRECT ANSWER✅✅The process by which green plants and some other organisms
use sunlight to synthesize foods with the help of chlorophyll.
Respiration - CORRECT ANSWER✅✅The biochemical process in which cells convert glucose and oxygen
into energy, carbon dioxide, and water.
Enzyme - CORRECT ANSWER✅✅A biological catalyst that speeds up chemical reactions in living
organisms without being consumed.
DNA - CORRECT ANSWER✅✅The molecule that carries genetic instructions for the development,
functioning, growth, and reproduction of all known living organisms.
RNA - CORRECT ANSWER✅✅A nucleic acid involved in protein synthesis and gene expression, serving
as a messenger between DNA and ribosomes.
