T-Test

Back 3

Deducing the significant difference
between two sets of data.

Front 4

Correlation

Back 4

A observation without an experiment.

Front 5

Statistics

Back 5

Mathematics that tells the difference in data.

Front 6

Polarity

Back 6

a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds.

a molecule of water is polar because of the unequal sharing of its electrons in a "bent" structure, whereas methane is considered non-polar because the carbon shares the electrons with the hydrogen atoms almost uniformly. Polarity underlies a number of physical properties including surface tension, solubility, and melting- and boiling-points.

Four Important Properties of Water

Back 7

Coolant: a fluid which flows through a device to prevent its overheating, transferring the heat produced by the device to other devices that use or dissipate it. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, and chemically inert, neither causing nor promoting corrosion of the cooling system.

Thermal: Specific heat; resistance to temperature

Cohesion:the part of shear strength that is independent of the normal effective stress in mass movements

Solvent:a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature.

Four Mono-saccharides Examples

Back 23

Glucose,fructose,galactose, Ribosome
Glucose: Main Fuel for our body and is found in polymers such as starch.
Ribose: a Fuel- carbon sugar, is used in modified forms of DNA.

Front 24

Di-Saccharides

Back 24

Two mono-saccharides put together.
examples:
Maltose= Glucose+Glucose
Lactose=Galactose+ Glucose
Sucrose=Fructose+Glucose

Front 25

Poly-Saccharides

Back 25

More than two saccharides

Example; Stardon, Glycogen, Celluose

Front 26

Uses in Animals

Back 26

Glucose: A mono with a function that has chemical fuel for cells

Lactose: A Di with a function that has one of solutes in milk

Glycogen: A Poly that stores glucose in the liver and muscles for quick release

Front 27

Uses in Plants

Back 27

Fructose: A mono in fruits, which gives sweetness energy for plant cells

Sucrose; A Di that transported from leaves to other Areas storage of energy

Cellulose: A poly which is the structure component of the cell wall in plant cells

Front 28

Lipids

Back 28

Molecules that store energy in their bonds over a long period of time. This energy becomes reserve energy only used with carbohydrates are in short supply.
Monomers: Fatty Acids, Glycerol
