BIO101 UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
COMPREHENSIVE STUDY GUIDE
●● What are the major characteristics of Life?
Answer: 1) reproduction (DNA (deoxyribose nucleic acid); double helix
shape; stores genetic info)
2) cellular repsiration (used to creat energy) (metabolism; need it to
perform basic functions of life; food (carbs, proteins, lipids/fats,
vitamins/minerals)
3) adaptation/evolve (over large periods of times traits of organizations)
modified
4) growth and development (DNA lays out the "plan")
5) organization (very specific; organization of organs/structure)
6) cells (basic building blocks of life; need only one to be considered
living)
7) respond (response to stimuli (light, touch, heat, etc.); need in order to
survive)
●● What is a cell?
Answer: - basic building blocks of life
- not always apparent; first seen with a microscope
- cells were discovered by Hook in 1655
,- first cells discovered were from cork
- theory wasn't generally accepted due to the challenge of trying to
convince people of this drastic change
●● What is cell theory?
Answer: - proposed in 1800's
- lowest level of structure perfoms all chracteristics of life
- arise from previously existing cells
●● What is metabolism?
Answer: - energy breakdown; needed for food
- glucose is the "best"
- C6H12O6 (formula for glucose)
- breaks (catabolic reaction) down to carbon dioxide and water [ CO2 +
H2O]
●● Difference between anabolic and catabolic reactions?
Answer: - anabolic- building up of molcules, etc.
- ie: anabolic steroids (build up muscle)
- catabolic- breaking down of molecules
●● Bean Beetle Lab
Answer: - learn how to determine if alive or dead
, - if alive, beetles should be giving off carbon dioxide
- if dead, bean beetles may be giving off CO2 but only
because the decomposition process
- CO2 measured in ppm
- calculate amount per bean beetle
x (ppm)/ number of bb = ppm/bb
every 15 mins = [x / # of bb] / 15
every 1 hour = [x/ #of bb] x 4
every sec = [x / # of bb] / 60
- used loggerpro prgm; used CO2 probe
●● Are viruses alive?
Answer: - depends on what you argue
- relies on a host cell to reproduce
●● What is science?
Answer: - latin "to know"
- asking questions about nature
- believe questions can be answered
●● Steps of the Scientific Method
Answer: 1) Make an Observation
