BIO Test 1 Flashcards
Hydrophillic (polar or nonpolar)
Polar
Hydrophobic (polar or nonpolar)
Nonpolar
Things needed for an experiment
Treatment group
Control group
Independent and Dependent variables
Placebos
Prediction
if…then
Hydrogen and Oxygen, which one do electrons like better?
Oxygen
Sugars end in…
oses
Enzymes end in…
ases
Are lipids hydrophobic or hydrophillic?
hydrophobic
What do nucleotides do?
provide the cell with the info for making proteins
What type of RNA is created from transcription?
mRNA
Allopatric Speciation
when a physical boundary pops up and creates a divide in species
Sympatric Speciation
specializing species to eat different food types
What can happen as a result of mutation? (4)
- Nothing
- Change an amino acid in the chain
- Early stop
- frame shift
Introns vs exons
introns-“commercials that you don’t need”
exons- the show that you actually watch
What is a mutation called that is beneficial
adaption
Reduction
gain in electrons
Start codon
AUG (met)
Are tails hydrophillic or hydrophobic?
Hydrophillic
Are heads hydrophillic or hydrophobic?
Hydrophobic
rRNA
ribosomal RNA
mRNA
messenger RNA
tRNA
transports subunits (anti-codon is here)
Bottleneck Effect
lots of creatures are eliminated so just a few are left
Founder Effect
little bit of the population goes off and starts new population-those genes happen to be common because there are only a few people starting the population
Oxidation
loss of electrons
Polymer
subunit-subunit-subunit
Covalent bond
shares electrons (VERY strong)
Subunit of proteins
amino acids
Do hydrophobic cells pass through easily or difficultly?
easily
Do hydrophillic cells pass through easily or difficultly?
difficultly
Do prokaryotic cells have a nucleus?
no nucleus
Do eukaryotic cells have a nucleus?
nucleus
What do electron carriers do?
gain and accept electrons
What is the role of the ribosome?
the site of translation
Migration
when the individuals from 1 population goes to another population
Migration leads to…
gene flow
