TEAS V Study Guide 2015 Science – Flashcards

Graphs to use when comparing measurements

What to use when summarizing measurements

What to use when observing correlation/regression between 2 variables

What to use when counts are taken instead of measurements

Investigation involving: making observations, make model, when want to find more info about unknown topics, do not require a hypothesis or use variables

An investigation Also known as "Controlled Experiments"; performed in a controlled environment, all variables are controlled except for one

An investigation involving: manipulating different groups in order to compare them to each other, no control group

all non-zero numbers, all zeros between non-zero numbers, all zeros that are both to the right of the decimal and at the end of the number, & all zeros to the left of the decimal if the number is greater than or equal to 0

Energy of motion; KE = 1/2mv

In order for work to be performed, a force has to be _______

This is soluble in water

The most common element in the atmosphere (78%)

This governs the activation energy of a reaction

Elements in the same group (column) in the periodic table have the same number of _____

This prevents UV rations from damaging life on earth

Organisms help each other survive

the source of mitochondrial DNA is ________

Stored energy; the form of energy that is contained in nutrient molecules and in ATP's high-energy bonds (bonds in molecules store potential energy for later use)

These bonds hold the water molecules tightly together so they cannot disperse easily, increasing surface tension and causing the "slap" when something hits the water

The biomolecule that influences the rate of specific chemical reactions within living cells

Nucleic acids, proteins, lipids, & carbohydrates

These are soluble in water and have high melting points

These are soluble in water and have low melting points

This is involved in the inflammatory response; it increases the permeability of capillaries to WBCs which allows the capillaries to engage pathogens in infected tissues -> so blood that contains infection-fighting cells rush to infected areas

The amount of energy needed to remove the most loosely bound electron; increases from left to right and increases from top to bottom on p. table

A type of WBC lymphocyte; responsible for the production of soluble antibodies

A type of WBC lymphocyte; it kills cancer cells, cells infected with with viruses, and other damaged cells

A type of WBC; engulfs & digests cellular debris, foreign substances, cancer cells, microbes in a process called Phagocytosis

Type of WBC; help Cytotoxic T cells & other immune cells by releasing T cell Cytokines

This decreases the birth rate in humans

These filter debris from intracellular spaces

These link the nucleic acid backbone sugars

Bonds between C and H (bc they have similar electronegativity)

A functioning unit of DNA which contains a cluster of genes under the control of a single promoter; in prokaryotes and eukaryotes

The process of a substance breaking down into a simpler substance; a form of respiration that takes place without oxygen
