,chapter 1: the science of life
1. which characteristic is common to all living organisms?
A. ability to move voluntarily
B. presence of a nucleus
C. ability to reproduce
D. presence of chloroplasts
ANS: c. ability to reproduce
rationale: all living organisms share fundamental characteristics, including repr
oduction, metabolism, growth, and response to stimuli. while not all organisms ha
ve a nucleus (prokaryotes lack one) or chloroplasts, reproduction is universal.
2. which level of biological organization is correctly arranged from simplest to
most complex?
A. organ → cell → tissue → organ system
B. cell → tissue → organ → organ system
C. tissue → cell → organ → organ system
D. organism → organ system → organ → tissue
ANS: b. cell → tissue → organ → organ system
rationale: biological organization progresses from simple to complex: cells form
tissues, tissues form organs, organs work in organ systems, and organ systems fu
nction in organisms.
3. homeostasis is best described as:
A. the ability to produce energy
B. maintaining a stable internal environment
C. the process of evolution
D. the creation of new species
ANS: b. maintaining a stable internal environment
rationale: homeostasis is the regulation of internal conditions such as temperatu
re, ph, and fluid balance, despite changes in the external environment.
, 4. the primary molecule for storing genetic information is:
A. carbohydrates
B. lipids
C. dna
D. proteins
ANS: c. dna
rationale: dna (deoxyribonucleic acid) contains hereditary information that gui des
growth, development, and reproduction in all living organisms.
5. evolution explains:
A. how individual organisms adapt during their lifetime
h
B. how populations change over generations
C. the immediate response of an organism to stimuli
D. the process of cellular respiration
ANS: b. how populations change over generations
rationale: evolution is the process by which populations of organisms change genetic
ally over time due to natural selection, mutation, and other mechanisms.
6. which of the following is a prokaryotic organism?
A. amoeba
B. bacterium
C. algae
D. yeast
ANS: b. bacterium
rationale: prokaryotic cells lack a nucleus and membrane-
bound organelles, which is characteristic of bacteria. amoebas, algae, and yeast ar
e eukaryotic.
7. which of the following best illustrates an emergent property?
A. chlorophyll in plants absorbing sunlight
B. water molecules forming liquid
