Nature of Science
The factor in an experiment that does not change.
What is a constant?
A large volume of ocean water flowing in a certain direction
What is an ocean current?
The new cell that forms from fertilization
What is a zygote?
The study of how traits are passed from parents to offspring
What is genetics?
A substance that consists of only one type of atom
What is an element?
This digestive organ is lined with tiny "fingers" called villi and absorption occurs here
What is the small intestine?
A possible explanation for an observation that can be tested by scientific investigations.
What is a hypothesis?
The vertical distance of a wave from crest to trough
What is wave height?
The ability to reproduce without a mate and producing many offspring
What are advantages of asexual reproduction?
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?
The expression of error as a percentage of the accepted value.
What is percent error?
The vertical movement of water toward the ocean's surface
What is upwelling?
Type of asexual reproduction in which an offspring grows on the body of its parent
What is budding?
Offspring that have parents that are true-breeding for different traits (ex. purple flowering parent and white flowering parent)
What are hybrids?
The mass per unit volume of a substance
What is density?
The tendency of an object to resist a change in motion
What is inertia?
Comparing what you know with information you are given in order to decide whether you agree with it.
What is critical thinking?
The movement of wind and water to the left or right that is caused by Earth's rotation
What is the Coriolis Effect?
This type of cell contains only one chromosome from each pair (23 chromosomes)
What is a haploid cell?
What geneticists call how a trait appears, or is expressed
What is a phenotype?
Substances will change state when this is added or removed
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.
Earth's distance from the Sun, 149,600,000 km, written in scientific notation.
What is 1.496 x 108 km?
This has the lowest tidal range and occurs when the Earth, Sun, and moon are at a right angle.
What is neap tide?
The order of the steps in Meiosis I
What are prophase I, metaphase I, anaphase I, and telophase I?
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?
In this phase of mitosis, sister chromatids are pulled away from each other to opposite ends of the cell
What is anaphase?
