100% VERIFIED ANSWERS|2025-2026 LATEST
UPDATE|ALREADY GRADED A+
the science of studying living organisms and life processes Correct answer-Biology
What are the characteristics of life? Correct answer-Complex, organized structure
Response to stimuli
Homeostasis
Ability to acquire material & energy
Growth
Reproduction
Ability to evolve
The complexity of life is built in ______ Correct answer-Levels
Life is both _______ and _________ Correct answer-Complexed and Organized
When two or more things come together, they develop a new property that was absent in the
individuals.
Ex:
Example: NaCl (Sodium Chloride)
Sodium = solid metal
Chlorine = poisonous gas
Put them together = table salt Correct answer-Emergent Property
Ex:
Example: NaCl (Sodium Chloride)
Sodium = solid metal
Chlorine = poisonous gas
Put them together = table salt
What are the levels of organization of life? Correct answer-(Most vague to most precise)
Biosphere, Ecosystem, Community, Species, Population, Multicellular Organism, Organ System,
Organ, Tissue, Cell, Organelle, Molecule, Atom, Subatomic Particle
Part of earth that sustains life, uppermost atmosphere to the deep sea. Includes both living and
nonliving aspects. Correct answer-Biosphere
Ex: Earth's surface
A community along with its nonliving surroundings Correct answer-Ecosystem
