An organism with a nucleus

of or relating to the poles of a cell, organ, or part

What is this

Values below 7 on the Ph scale

A very large molecule

What is NOT a characteristic of life

the minimum quantity of energy that the reacting species must possess

the study of living organisms

Polio, chicken pox, cold, flu are all types of what

When a concentration of two soloutions are the same

No charge

Strong, supporting layer around the cell membrane in some cells

a type of bond that occurs when two atoms share a pair of electrons with each other

Process by which particles tend to move from an are of high concentration to low concentration

a network of membranous tubules within the cytoplasm of a eukaryotic cell

Positive, negative, and none are types of what

The powerhouse of the cell

the sticking together of particles of the same substance

Long strands of fatty acids

Thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell

a substance produced by a living organism that acts as a catalyst

Molecules that consist on long chains of nucleotides

the group in an experiment that receives the variable being tested

Organic compounds found in food, such as sugars

proteins involved in the movement of ions, small molecules, or macromolecules

The center of an atom

An organism with no nucleus

the basis of the fluids of living organisms

movement of biochemicals across cell membranes without need of energy input.

Composed of long chains of one or more amino acids

When comparing two soloutions, the solutions with the greater concentration of soloutes

Well-tested explanation that unifies a broad range of observations and hypotheses

What type of cell is this

The center of an atom

a substance that takes part in and undergoes change during a reaction

Negatively charged

measurement, and experiment, and the formulation, testing, and modification of hypotheses

Posotively charged

the basic unit of a chemical element

a cell transports molecules into the cell by engulfing them in an energy-using process

Possible explanation for a set of observations or possible awnser to a scientific question

Process of diffusion in which molecules pass across the membrane through cell membrane channels

a variable whose value depends on that of another

proteins expressed on the surface of cells that often conveniently serve as markers

Substances that cannot be broken down into simpler substances

a region on an enzyme that binds to a protein or other substance during a reaction

What type of cell is this

not "true fats" because they have one of the fatty acids replaced by a phosphate group

A measure of acidity or basicnes of water soluble substances

She comparing two soloutions, the soloution with lesse concentration of solutes

a variable whose variation does not depend on that of another

Diffusion of water through a selectively permeable membrane

a substance produced during a natural, chemical, or manufacturing process.

organelle that captures energy from the sun and converts it into chemical energy

the movement across a cell membrane into a region of higher concentration, requiring energy.

Process of noticing and describing events or processes in a careful, orderly way

an optical instrument used for viewing very small objects.

the complete transfer of valence electron(s) between atoms

a chemical bond that involves the sharing of electron pairs between atoms

the group in an experiment or study that does not receive treatment by the researchers

Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell

the sticking together of particles of different substances

a region on an enzyme that binds to a protein or other substance during a reaction

Above 7 on the Ph scale
