Wrong Pile 2 Flashcards
What are the different units for the density of water?
1 g / cm(cubed)
1 kg/ m (cubed)
1 g / ml
1000 kg / L
At what point do a liquid begin to evaporate, in terms of vapor pressure & boiling point?
When the vapor pressure = boiling point, then the liquid begins to evaporate.
What feature of water molecules allows it to be less dense in the solid state?
Most molecules become tightly packed together when they turn into a solid. However, the structure of water molecules allows for it to have lots of empty space.
Describe beta decay in detail
Beta Decay occurs when a neutron is converted into a proton. Also, there is an emission of an electron in the process. Gamma radiation
Why are children more likely to be used in studies of contamination, dosages as opposed to adults?
Children weigh less than adults, so they have a higher relative dosage than compared to adults at the same level of contamination.
What is the -al ending in organic chemistry represent?
Aldehydes.
What is the -oate ending in organic chemistry represent?
Esters.
What is the -one ending in organic chemistry represent?
Ketone.
What is the function of the boiling chip and vacuum in distillation?
Boiling chips prevent super heating.
Vacuum lowers the boiling point.
What is the formula and units for torque?
Torque = Force ( Level Arm ) sin angle. Perpendicular allows for the most torque.
Units: Newton Meters.
Relate pH and pKa
If pH pKa then deprotonated.
Describe Newton’s third law:
Fab = -Fba.
Describe diatomic nitrogen
triple bonded, very inert gas.
What are lyases?
break molecules into two smaller molecules without using water or redox reactions
Which amino acids form disulfide bridges?
Cysteine. CC. CysCys.
Describe the movement of electrons along the electron transport chain:
The electrons move along the ETC from a low reduction potential to higher and higher reduction potentials. The last reaction with oxygen therefore has high reducing potential. This makes sense because you’re going from O2 to H2O. The removal of oxygen and the addition of two hydrogens.
What is the shortcut to calculate hybridization?
Count the bonds and lone pairs, then add them to make the hybridization.
What is long term potentiation
Succesful neural interaction survival.
What is retrograde amnesia?
Loss of memory of the events just before the accident.
What is anterograde amnesia?
Loss of ability to form new memories.
Define retrospective, prospective, field embedded, and longitudinal research.
retrospective: past research
prospective: proposed to review incoming data.
field embedded: researchers posed as patients
longitudinal study: study over time period.
What is a moderator variable?
Factors that change the strength or direction of the independent and the dependent.
What is a mediator variable?
Explains the relationship that leads to the dependent variable.
What is a confounding variable?
A confounding variable is one which is not typically of interest to the researcher but affects the relationship between the dependent and independent variables
