Organisms
This organelle is known as the “control center” of the cell because it contains DNA.
The Nucleus
Only about this percent of energy passes from one trophic level to the next.
10%
A warm air mass slowly pushing over a cold air mass creates this type of front.
A Warm Front
This subatomic particle has a positive charge and is found in the nucleus.
This universal force states that an object at rest stays at rest and an object in motion stays in motion.
Inertia (or Newton's First Law)
This organelle uses sunlight to make food through photosynthesis.
The Chloroplast
This type of succession would most likely occur after a forest fire because the soil is still present.
Secondary Succession
This atmospheric process traps heat near Earth’s surface and is necessary for life in normal amounts.
The Greenhouse Effect
The atomic number of an element tells you the number of these particles in an atom.
Protons
This law states that for every action there is an equal and opposite reaction.
Newton's 3rd law of motion
A student observes an organism with one dominant brown fur allele and one recessive white fur allele. What fur color will the organism most likely have?
Brown Fur
Competition, predation, and disease are all examples of these types of limiting factors.
Density-dependent factors
Warm air masses usually create this type of pressure system because warm air rises.
Low pressure system
A substance with a pH of 2 would be described as this.
Acidic
In an experiment, the variable that is purposely changed by the scientist is called this.
This organelle acts like the cell's "security gate" by controlling what enters and leaves the cell.
The Cell Membrane
This type of dispersion occurs when organisms are grouped together because resources are concentrated in certain areas.
Clumped dispersion
This property describes how much sunlight a surface reflects.
Albedo
This type of bond forms when atoms share electrons.
A covalent bond
This formula is used to calculate force.
F=ma
A rabbit has the genotype Bb, where B is a dominant allele for black fur and b is a recessive allele for white fur. This visible fur color would be called this.
A Phenotype
These organisms are known for being pioneer species during primary succession (list two!)
Mosses and Lichen
Name two things that absorb carbon dioxide from the atmosphere.
Possible answers: Plants (photosynthesis), Oceans, Soil
This periodic group is known for commonly bonding with the alkali metals.
The Halogens
A student wants to test how the acidity of water affects plant growth. This would be the control group for this experiment.
Normal/Pure water (balanced pH of 7)
