Question 1

What is flow rate dependent on?

Answer 1

• Directly proportional to r^4 and ∆Pressure

- Indirectly proportional to viscosity

Question 2

What has higher energy: microwaves or X-rays?

Answer 2

Microwave has lower energy and longer wavelength

Question 3

Surface tension

• Units
• Relation to temperature

Answer 3

Tendency of liquid to resist external force

• Energy/area
• Decreases as temperature increases

Question 4

Work done by liquid

Answer 4

P∆V

• Area under pressure-volume curve

10^-5

Question 7

Velocity of sound equation

Answer 7

v = √B/rho

• Solid v > liquid v > gas v
• Stiffer object = faster sound

Question 8

Magnetic field strength

Answer 8

β = µoI/2r

• uo = permeability of space
• I = electrical current

Question 9

Equation of continuity

Answer 9

Q (constant) = A1v1 = A2v2

Question 10

Volume flow rate

Answer 10

Q = Av = V/t

Question 11

Viscous force

Answer 11

Fv = nAv/d

• Decreases as temperature increases

Question 12

Poiseuille’s Law

Answer 12

V/t = ∆Pr^4/nL

Question 13

Venturi effect: constrict pipe => ____

Answer 13

Increased velocity => decreased pressure

Question 14

Surface tension

Answer 14

T = F/L*Temp

Question 15

Water + ester

Answer 15

COOH and OH

Question 16

OH + ester

Answer 16

Transesterification

Replace O of ester w/ O and carbon chain of alcohol

Question 17

COOH derivatives reactivity ranking

Answer 17

Acid halide > acid anhydride > ester > amide

Question 18

Hydrolysis of amides

Answer 18

Turns into COOH

• Acid catalyzed (add H+ and H2O)
• Base catalyzed (add base and heat first, then H+)

Question 19

Alpha decay

Answer 19

Emit helium atom

Question 20

Beta decay

Answer 20

Emit electron => gain proton (from neutron)

Question 21

Positron emission

Answer 21

Emit positron => gain neutron (from proton)

Question 22

Gamma decay

Answer 22

Release high frequency gamma rays

Question 23

Lysosomes

Answer 23

Cell’s digestive/trash system

Question 24

Answer 24

A, D, E, K

Question 25

Water-soluble vitamins

Answer 25

B and C

Question 26

What does polyadenylation do for RNA?

Answer 26

Helps with nuclear export, translation, and mRNA stability

Question 27

Types or restriction enzymes

Answer 27

• Type I = remote, use ATP and S-adenosyl-L-methionine
• Type II = short distance, use Mg2+
• Type III = short distance, use ATP, stimualted by SALM
• Type IV = target modified DNA

Question 28

Cell membrane is impermeable to _____ and _____ molecules

Answer 28

Ions and polar molecules

Question 29

Humoral immunity

Answer 29

B cell mediated (adaptive)

• Antibodies and immunoglobulins

Question 30

Moderating variable

Answer 30

Specifies when IV and DV are related

Question 31

Mediating variable

Answer 31

Helps IV get to DV more directly

Question 32

Cannon-Bard theory of emotion

Answer 32

Feel fear and have physiological response at same time

• Bard sings while cannon goes off

Question 33

James-Lange theory of emotion

Answer 33

Want Justice, then you get the League
