BIOL 2070 - LECTURE 1 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
What are the basic steps of the scientific method?
Scientist makes an observation and asks a question. Then they formulate a hypothesis
to then generate predictions to be tested. Results of the testing will either support or
reject your hypothesis
What is Le Chatalier's principle?
if any change occurs to equilibrium, the system will shift in a way that brings it back to
eq.
All cells consist of what?
A plasma membrane surrounding a cytoplasm, DNA, ribosomes, and protein systems
A single unit is defined as what?
Unicellular
A group of cells joined together and functioning as a unit is called what?
Multicellular
True or False: Cells reproduce themselves to make more cells
True
What is cell theory?
All living things are made up of cells, cells are the basic units of structure and function in
living things, new cells are produced from existing cells; all present-day cells evolved
from a common ancestor
, Cells are grouped into types according to their predominant what?
Characteristics
Prokaryotic cells are broken into what two groups?
Eubacteria and archaebacteria
Animal cells are what type of cell?
Eukaryotic
What are the characteristics of prokaryotes?
- No nucleus
- No membrane bound organelles
- Circular genome
- Peptidoglycan cell wall
- No cytoskeleton
- Unicellular
- No histones
- Ribosome 70s
- transcription and translation are coupled in cytoplasm
Differentiate eukaryotes from prokaryotes
- Nucleus
- Membrane-bound organelles
- Linear genome
- Cellulose or chitin cell wall if present
- Cytoskeleton
- Multicellular
