Science Flashcards
(48 cards)
independent
changing
dependent
being measured
control
stays the same
variables
independent
dependent
control
gametes
sex cells
holds half of the chromosomes
(23)
amino acids
building blocks of proteins
ATP
primary source of energy
Endothermic vs. Ectothermic
endothermic: warm blooded, took in energy
Ectothermic: cold blooded, released energy
vertebrate
has a spine
water’s freezing and boiling points in Celsius
freezing: 0 C
boiling: 100 C
convection vs. conduction
energy travels through . . .
liquid or gas: convection
solid: conduction
potential and kinetic energy
energy of . . .
potential –> . . . height
kinetic –> . . . motion
mechanical energy
what does it mean to be “conserved”
sum of potential and kinetic energy
conserved: same in the end as in the beginning
relationship between current and resistance in an electrical circuit
as resistance goes up current goes down
inverse relationship
△ T
△ T
“Change in”
final - initial = △ T
pH scale
know numbers, labels, and examples (alkaline)
9
bases “ammonia”
8
7 : neutral “water”
6
acids “vinegar”
5
density
what is the equation?
what will float?
d= mass/volume
less dense-floats
more dense-sinks
pressure formula
what relationship do the three variables have?
P V = T
direct: P↑ & T↑
inverse: P↑ & V↓
Pressure and volume: inverse
pressure and temperature: direct
temperature and volume: direct
“kilo”
“centi”

(king henry doesn’t usually drink chocolate milk)
1 kilogram = 1000 grams
100 centimeters = 1 meter
planets
terrestrial “dirt”←l→ gas glants

MVEM JSUN
direction of the electric field
positive downward to negative
photosynthesis equation
light+water+CO2 –> sugar + O2
photosynthesis occurs in what part of the cell
chloroplast
Chromosomes located
in the nucleus
