copy deck
The space between the cell membrane and the nucleus of a cell.
An organism's genetic makeup, or allele combination. (example, TT, Tt, tt)
Sample Size
The number of items in a sample; in general, a larger sample size yields better statistical information than a smaller sample size; large sample size can decrease the effect of random variation and make trends and predictions more accurate.
A membrane-bound organelle in the cytoplasm of most cells containing various enzymes that function in digestion.
nuclear membrane
The membrane enclosing the nucleus of a cell. Also called nuclear envelope.
The scientific study of variation and heredity.
a scientist who traces the spread of disease through population

The likelihood that a particular event will occur.
The passing of traits from parents to offspring.
Small round organelles found in the cytoplasm of living cells that serve as the site of protein synthesis.
Subject to change; a quantity able to assume different numerical values; in an experiment, it is the value that is changed or controlled in order to isolate and identify what is causing the observed effect.
selectively permeable
Describes a structure that allows certain substances to pass through, but not others
a lack or shortage of something
An organism's physical appearance, or visible trait. (example, orange tailed)
creatures tht are to small to be seen with the naked eye

asexual reproduction
The reproductive process that involves only one parent and produces offspring that are identical to the parents.
Qualitative Data
Information that is difficult to measure, count, or express in numerical terms; used in research involving detailed, verbal descriptions of characteristics, cases, and settings; typically uses observation, interviewing, and document review to collect data.
a inactive substance or preperation used as a control in an expirement or test to determine the effectivness of a medical drug
By chance, like the flip of a coin
the act of conducting a controlled test or investigation
a breakdown in the structure or function of a living organism
An explanation for an observation or scientific problem that can be tested by further investigation.
the isolation of a person or animal who has a disease
the basic unit of structure and function in living things
the viewing and recording of data
informed consent
a form signed by volunteers in a clinical trail that states they have been told(informed) about the risks and that they agree(consent) to participate in te trail
scientific method
1. state problem/question 2. propose explanation ( hypothesis) 3.collect evidnece/conduct expirement4.analyze data 5. draw conclusion(repeate expiremnt if necessary
A section that is cut along the width (or middle) of a structure.
A structure within a cell, such as a mitochondria, vacuole, or chloroplast, that performs a specific function and contributes to the life of the cell as a whole.
ogical conclusion based on factual knowledge or evidence
A specific variation of a characteristic that an organism can pass on to its offspring through its genes.
a type of organism that is made up of many cells/ a type of organsim that is made up of one cell
sexual reproduction
The reproductive process that involves two parents who combine their genetic material to produce a new organism, which differs from both parents.
Product of reproduction, a new organism produced by one or more parents
the exchange of one thing in return for another, giving up one benifit or advantage for another regard that is more disirable, an exchange that occurs as a compromise
