July 21st (altius exam 1)

Question 1

social facilitation

Answer 1

the tendency to do better when we know others are watching

Question 2

family, peers, school, religion etc act as ________ to tech as the norms of society

Answer 2

agents of socialization

Question 3

operant conditioning vs classical conditioning

Answer 3

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

Question 4

percent difference

Answer 4

change in value diveded by starting value x 100

Question 5

explain real gases deviating from ideal gas law

Answer 5

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

Question 6

combined gas law

Answer 6

PV/T

Question 7

find density from ideal gas law arrangments

Answer 7

density= PM/RT

Question 8

average KE

Answer 8

KE = 1/2 mv^2 = 3/2 Kb T

Question 9

root mean square speed

Answer 9

√ 3RT/ M (in kg/mol)

Question 10

oxygen molecules travel at a speed of 500m/s, whats the average speed of a hydrogen at this same temp

Answer 10

r1/r2 = √M2/M1 (this is going to be so helpful!)

Question 11

what is vapor pressure

Answer 11

the pressure that evaporated particles exert above a liquid

Question 12

what is partial pressure

Answer 12

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

Question 13

how can I find Pt

Answer 13

add up all Pa

Question 14

why would I have more oxygen dissolved in my blood if I’m at sea level compared to in Kimberley

Answer 14

at sea level–> greater Pt = greater Pa –> means that more [A] will dissolve

[A]/P = k, if one increases the other increases

Question 15

1 atm = Pa?

Answer 15

1.0 x10^5 Pa

Question 16

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.

Answer 16

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),

Question 18

belief perseverance vs confirmation bias

Answer 18

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)
