July 21st (altius exam 1) Flashcards
social facilitation
the tendency to do better when we know others are watching
family, peers, school, religion etc act as ________ to tech as the norms of society
agents of socialization
operant conditioning vs classical conditioning
operant- learning an association between a behaviour and a consequence ( positive punishment)
classical- associating an involuntary response (drool) and a stimuli (bell)
- dog drooling to the sound of a bell
percent difference
change in value diveded by starting value x 100
explain real gases deviating from ideal gas law
ok so basically we have this ideal gas law stating the relationship between 4 gas varibles PV=nRT
however, this is for ideal gases, in reality real gases deviate from these values slighlty
(P + n^2 a / V^2 ) (V-nB) = nRT
these two correction factors are a = attractive forces and b = big particles- particles volume
so if a particle has large volume –> the volume variable is going to be smaller- to compensate either V or P needs to increase –> so if in set container, P will increase for this particle,
- if a is large= P needs to get smaller to compensate for the larger corrective factor
large attractive forces- pressure is less than what is ideally expected
large volume of particle= volume is more than what ideal law predicts
combined gas law
PV/T
find density from ideal gas law arrangments
density= PM/RT
average KE
KE = 1/2 mv^2 = 3/2 Kb T
root mean square speed
√ 3RT/ M (in kg/mol)
oxygen molecules travel at a speed of 500m/s, whats the average speed of a hydrogen at this same temp
r1/r2 = √M2/M1 (this is going to be so helpful!)
what is vapor pressure
the pressure that evaporated particles exert above a liquid
what is partial pressure
when we know the total pressure in a container with a mixture of gases, the partial pressure is the pressure that each gas exerts
Pt= Pa x Xa
how can I find Pt
add up all Pa
why would I have more oxygen dissolved in my blood if I’m at sea level compared to in Kimberley
at sea level–> greater Pt = greater Pa –> means that more [A] will dissolve
[A]/P = k, if one increases the other increases
1 atm = Pa?
1.0 x10^5 Pa
AITA is a single-stranded RNA virus. For genomic replication to occur, the virus must package its own RNA polymerase into the virion because eukaryotic host cells:
- lack an enzyme that can synthesize RNA from RNA.
- lack an enzyme that can synthesize DNA from RNA.
- lack an enzyme that can synthesize RNA from DNA.
- utilize RNA that is structurally different from viral RNA.
lack RNA from RNA
- Answer A is correct. Eukaryotic cells do not generate RNA from RNA, and therefore eukaryotic cells do not have enzymes that perform this function. To make mRNA for either protein synthesis or new genomic material, RNA viruses such as the influenza virus must possess an RNA-dependent RNA polymerase, as suggested by answer choice A. Eukaryotes also lack an enzyme that can synthesize DNA from an RNA molecule, which could make Answer B tempting. However, the influenza virus never uses DNA in its replication cycle (as noted in Paragraph 1),

belief perseverance vs confirmation bias
A confirmation bias is a bias in which people seek out and recall information that supports their preconceived beliefs. (seeking only more info that will supporty your belief)
In contrast, belief perseverance doesn’t involve using information to confirm a belief, but the rejection of information that could disprove it. (rejecting info that could disprove it)
