CAL POLY BIO 123 MIDTERM 1
QUESTIONS AND ANSWERS
What is Bio? — - Correct Answers -the study of life
What categorizes what is living? — - Correct Answers -exchanging something with the
environment
metabolism
reproduction
What is sex?— - Correct Answers -offspring that has genetic material from 2 parents
scientific method - Correct Answers -1) Ask Question
2) Propose Hypothesis
hypothesis: Enzyte cause an increase in penis size
null hypothesis: Enzyte does not cause an increase in penis size
3) Design Study (exper/obv)
4) Make Predictions
5)Perform Study, Analyze Data
-were predictions met?
YES=hypothesis supporterd, null rejected
NO=hypothesis rejected, null accepted
independent variable - Correct Answers -x axis
is the one that is changed by the scientist
ex: amount of vitamin that is given
dependent variable - Correct Answers -y axis
responds to the change made to the independent variable
ex: life span
Genetics: - Correct Answers -explain how traits are passed on by parents to offspring
dragonflies - Correct Answers -up to female: if females wants, she attached back to him
forming a heart shape
Bacterial Diversity - Correct Answers -shape
size
mobility
, How to bacteria obtain new genes - Correct Answers -from dead bacteria
from viruses
from other living bacteria
when bacteria mate w each other: - Correct Answers -combining DNA that creates
something entirely new—like sex
NOT actually sexual reproduction—its 2 living organisms and one hands their DNA over
Alexander Flemming - Correct Answers -lab technician
messy, careless, bad scientist
discovered penicillin—left his bacteria out for 2 weeks and mold took over
helped WWII
trait: - Correct Answers -any characteristic you can see, have, or observe
DNA - Correct Answers --found in nucleus
-chromosomes are tightly packed bundles of DNA
-some chunks of DNA are genes and other DNA are "junk" DNA, not genes
watson and crick - Correct Answers -created model of double helix DNA (and Franklin
but she did not receive nobel prize credit)
double helix - Correct Answers -double strands held together by base pairs
base pairs are given letters
A with T, C with G,
sequence of the base pairs determine - Correct Answers -what genes will be produces
and ultimately what traits will be produced
master plan for inv biological system
Central Dogma - Correct Answers -akes DNA inside nucleus to make RNA
RNA - Correct Answers -disposable blueprints of the chunks of DNA that contain genes
RNA blueprint is used to string together to make proteins
those proteins are responsible for our phenotype
phenotype - Correct Answers -responsible for how we look, behave, physiology
can be affected after birth (diet, exercises, lifestyle)
genotype - Correct Answers -the DNA sequences that each of us has for a specific trait
How do traits get passed onto the offspring - Correct Answers -chromosomes are paired
(one from dad one from mom)
Allele: - Correct Answers -a version of a gene (AA, aa, Aa)
