2 pints

4 quarts

angle greater than 0^o and less than 90^o

exactly 90^o

greater than 90^o and less tha 180^o

measures exactly 180^o

two or more angles whose sum is 90^o

two or more angles whose sum is 180^o

No two angles of a scalene triangle are equal to each other

Always has two equal angles

all three angles equal 60^o

all 3 angles are less than 90^o

One angle greater than 90^o

• polygon with 4 sides
• Sum on the angles is always 360

contains genetic information or DNA and controls the cell activity

a semipermeable membrane that seperates the contents of the cell from the surrounding fluid

fluid matrix found between the plasma membrane and the nucleus that acts as scaffolding for the organelles

"Little organs" specialized units in the cell that perform certain functions

Location of cellular respiration which is the conversion of food to energy at the cellular level

Site of protein synthesis in the cess

Means for transporet within the cell and is made up of many channels

has ribosomes on its surface. Serves to store and deliver protein made by the attached ribosmes

storage of enzymes and minerals and the folding of proteins

modifies and packages proteins destined for use int he cell or for export from the cell

sacs that sontain strong digestive enzymes responsible for digesting cell structures that are no longer living or that are malfunctioning and for digesting waste

can be distinguished by the facts that they are surrounded by a cell wall and contain chloroplasts

compartments in the cytoplasm that act as places for secretion, excretion and storage

Involves use of energy in the form of ATP to move substances across the membrane

Does NOT require energy and makes use of diffusion and filtration

Particle move in a random manner spreading evenly throughout and available space and moving from regions of high concentration to lower concentration

Water moves from an area of high water concentration to and area of low water concentration

solute concentration of the water is the same as that inside the cell

solute is more concentrated outisde of the cell than inside

solute concentration outside the cell is lower thatn that inside the cell

obtain their food by consuming plants or animals

carnivores or omnivores that eat herbivores

carnivores that eat other carnivores or omnivores

individuals with contrasting traits are crossed, the dominant trait is expressed and the recessive trait is masked

when two hybrids are crossed the hidden trait becomes segregated and appears in 25% of the offspring

genes on different chromosomes are inherited independently of each other

magnifies up to 2000 times

magnifies up to 2 million times

connect bone to bone

connect muscle to bone

allows light to enter the eye

• eye color
• changes in size regulating how much light is allowed to enter the pupil

focuses light onto the retina

innermost layer of the eyeball and contains two types of photoreceptor cells

• sensitive to light
• distinguishes between black and white, and allows us to see at night

allows to distinguish colors in the day

positive chargee and found in nucleus

Neutral and found in nucleus

is equal to the number of protons found in the nucleus of each of its atoms

equal to the number of nucleons(protons + neutrons)

atoms form molecules by sharing pairs of electrons

two atoms sharing electrons equally

two atoms share electrons unequally

gas to liquid

direct change between the solid phase and the gaseous phase without a liquid phase

denotes hydrogen ions

denotes hydroxide ions

turns blue-black in the presence of starch

when heated with a simple sugar turns red

• distance that and object is from some starting point
• measured in units of length

• displacement is constantly changing
• described by displacement, velocity(speed) and acceleration

distance traveled by an object per unit of time

S=distance traveled/time

• speed in a given direction
• speed and direction

Acceleration=final velocity-original velocity/time

M=mass x velocity

objects in motion tend to stay in motion and that objects at reast tend to stay at rest

relationship between force, mass and acceleration

force=mass x acceleration

ability to do work

kinetic energy=1/2 (mass x velocity)²

stored energy

work=force x distance

When temperature is constant, the pressure of a gas varies inversely with its volume

volume of a fixed amount of gas varies directly with its temperature. If temperature increased, volume increases

Kelvin=Celsius + 273

Fahrenheit=(9/5+celsius) + 32

Maximum distance a wave rises or falls as it travels

• Brightness with light
• Loudness with sound waves

how oftne a cycle repeats itself in s specific time unit

occurs when the vibration of one system results in the vibration of the other system at the same frequency

has to do with frequency

the bending of light rays as they pass from one medium to another because light moves at different speeds through different mediums

electric force between two charges is proportional to the product of the two charges

power = voltage x current

watts=volts x amperes
