This digestive organ is lined with tiny "fingers" called villi and absorption occurs here
What is the small intestine?
The primary function of a radio station's tower in a communication system...
What is a transmitter?
The vertical distance of a wave from crest to trough
What is wave height?
The transfer of thermal energy between two items that are touching.
What is conduction?
A genetic factor that is blocked by another genetic factor
What is a recessive trait?
A type of mixture in which the substances are not evenly mixed
What is a heterogeneous mixture?
This cell organelle stores nutrients, water, and other things the cell may need in the future
What is a vacuole?
This is the manufacturing process in which tools such as wrenches, bolts, screws, and screwdrivers would probably be most useful.
What is combining (or assembling?)
The vertical movement of water toward the ocean's surface
What is upwelling?
What is stored energy that depends upon the relative position of various parts of a system
What is potential energy?

What are hybrids?
What type of matter cannot be easily separated by physical means?
What is a substance (or a compound)?
The tendency of an object to resist a change in motion
What is inertia?
an early sample, model, or release of a product built to test a concept or process
What is a prototype?
The movement of wind and water to the left or right that is caused by Earth's rotation
What is the Coriolis Effect?
The three types of heat transfer are...
What are radiation, conduction, and convection?
What geneticists call how a trait appears, or is expressed

What is energy?
This is the equation for density
What is density equals mass divided by volume?
Or d=m/v.
Or d=m over v.
This is the first step in the Engineering Design Process (and the scientific method...)
This has the lowest tidal range and occurs when the Earth, Sun, and moon are at a right angle.
What is neap tide?
A form of potential energy stored in an object due to a force that temporarily changes its shape, such as squashing or stretching...
What is Elastic energy or potential elastic energy?
When multiple genes determine the appearance of a trait
What is polygenic inheritance?
What is the balanced equation for
N2 + H2 --> NH3?
What is N2 + 3H2 --> 2NH3?
This is Newton's Law that states for every action there is an equal but opposite reaction.
What is Newton's Third Law of Motion?
