BIO-100 EXAM 1 RVC PR. LEDIN
QUESTIONS & ANSWERS (RATED A+)
Science - ANSWERThe study of the natural world
Biology - ANSWERThe study of life
How are eukaryotic cells different from prokaryotic cells? - ANSWEREukaryotic cells
have a nucleus
What three basic components are found in eukaryotic cells? - ANSWERNucleus,
plasma membrane, and a cytoplasma (cytosol and organells)
Why are cells small? - ANSWERTo maintain a high surface to low volume rate
What are atoms composed of, explain atomic structure? - ANSWERNucleus (made
up of protons and neutrons), Electrons, and Neutral atoms
What is indicated by Atomic number? - ANSWERThe # of protons in the nucleus
What is indicated by Mass number? - ANSWERThe number of protons and neutrons
What is an isotope? - ANSWERAtoms of a particular molecule that have the same
numbers of proton, but have different numbers of neutrons. They can have the same
atomic number, but different atomic masses.
How permeable is the plasma membrane? - ANSWERThe plasma membrane is
selectively permeable
What components are found as part of the plasma membrane? - ANSWERPolar
heads, non polar tails, cholesterol, and proteins
1) characteristic of life - ANSWERDifferent molecular composition than nonliving
things.
2)characteristic of life - ANSWERRequire energy and raw materials (Food)
3)characteristic of life - ANSWERLiving things are composed of cells (has to be at
least one cell)
, 4)Characteristic of life - ANSWERMaintain homeostasis (stable internal environment
despite external conditions)
5)Characteristic of life - ANSWERRespond to external environment (Ex. Turning
head towards a sound)
6)Characteristic of life - ANSWERGrow and Reproduce (Pass on favorable traits
through DNA)
7)Characteristic of life - ANSWEREvolve (how organisms change over time)
