difference in amount of energy carbohydrates, fats, and proteins provide is…
arrangement, type, and number of atoms in molecule
commonly shared atoms between fats, proteins, and carbohydrates
C, H, O!
simple carbohydrates
one subunit, sweet, soluble in water
complex carbohydrates
many subunits, bland, NOT soluble in water
why do fats provide more energy?
more atoms (triglyceride), and has a bigger # of oxygen atoms
experiment design + variables (6)
conditions, constant variables, DV, IV, sample size, variables
conditions
circumstances under which an experiment will test something
constant variables
variables that stay the same
DV
variable that relies on the IV
IV
variable that is purposely changed to see outcome (DV)
Sample size
count of individual samples+observations (ex: too small provides unreliable results, too big asks for too much time&resources)
