What are platelets?
Platelets are cell fragments and do not have nuclei
What effect does a leak in the distillation apparatus have on boiling point?
Leaks in a distillation apparatus increase surface tension, increasing boiling point
How do you calculate half life?
T1/2 = 0.6931/k
How do you find the change in frequency from two wavelengths?
Convert the wavelengths to frequency and use c = (frequency)(wavelength)
What is the path of sperm?
Epididymis, vas deferens, urethra, vagina, cervix, uterus, fallopian tube
What is a regulatory function of skin?
Skin can regulate body temperature; when skin stand up it traps air in a layer, providing insulation
What does normal spermatogenesis produce?
4 haploid sperm cells
How do people with self-serving biases respond to situational variables?
Individuals experiencing self-serving bias attribute their own negative behaviors to situational variables
What are the components of the knee-jerk response?
sensory neuron, motor neuron
What is drive in the psychodynamic theory?
Drive is a negative state of tension created when needs are not met
How does group polarization affect focus groups?
Group polarization affects attitude towards a topic as when people discuss together their views tend to get more polarized
What are the characteristics of the 4 stages of sleep?
NREM1 has low brain activity and blood pressure, NREM2 has decreased muscle activity and no consciousness of the external environment, NREM3 is deep sleep with regular breathing and slow brain waves, REM is the deepest stage with partial paralysis and vivid dreams
What is anomie?
Anomie describes the alienation that individuals feel when social norms and social bonds are weak
How does the ideal gas law change at high pressures?
At higher than atmospheric pressure the volume of gas particles in not negligible
Why can light travel long distances without dimming?
Internal reflection allows light to be carried long distances with little amplitude loss, it can propagate forever if nothing absorbs it
What happens when a basic salt is in an aqueous solution?
The anion of a basic salt reacts with water to produce hydroxyl ions
How do you calculate moles given the mass of a compound?
To find the number of moles in a reaction: grams/molar mass
Why do transition metals change colors?
When electrons in lower energy d orbitals absorb visible light they move to the higher energy d orbitals, causing energy absorption that turns solutions a certain color
How does hydrogen bonding effect stereoisomers?
Hydrogen bonding can make stereoisomers have different stability
What is an equation for buoyancy?
F_b = ρ * V * g
How is density related to depth and pressure?
The pressure in a liquid due to the gravitational force of the liquid above a given depth is proportional to the density and the depth
How is pressure related to velocity in a fluid carrying pipe?
The pressure of a liquid in a pipe is greatest where the fluid velocity is lowest
How does Ohms law relate current and resistance of parallel resistors?
Currents in parallel resistors are inversely proportional to their individual resistances because they have the same voltage drop across them
How can you find blood pressure in different parts of the body?
Blood pressure in the body can be determined by rgh and is independent of blood flow or viscosity
