This RNA is transcribed from a section of DNA and later leaves the nucleus in order to be translated into an amino acid chain.
mRNA

A students observes a cell where the chromosomes appear to be pulled apart by spindle fibers. These two final steps would come after this.
Telophase and cytokinesis

In ecology, organisms are classified as autotrophs and heterotrophs, regarding what they eat. -troph refers to food, auto refers to self, and hetero refers to different/other.
Which word likely refers to photosynthetic organisms such as plants and algae?
Autotrophs
200
Newton's first law states that an object at rest stays at rest unless acted upon by this.
What is a net/unbalanced force?
200
This type of bond forms when one atom transfers electrons to another, creating oppositely charged ions.
What is an ionic bond?
200
This theory explains how Earth's lithosphere is broken into moving sections that drive earthquakes and volcanic activity.
What is plate tectonics?
200
Early in a test, if I am unsure of an answer I should do this...
Flag the question and move on.
300
The process by which water moves through the cell membrane to balance out a high concentration of solutes.
Osmosis
300
Water molecules have attractive forces to one another and are held together by these types of weaker bonds
Hydrogen bonds
300
This is the process by which organisms break down glucose, without the use of oxygen, to create ATP
Anaerobic cellular respiration
300
Fix this statement or explain why it is false.
Plants use photosynthesis for energy and animals use respiration.
Animals use respiration, plants use both respiration and photosynthesis.
300
A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
Keystone species
300
This type of energy is stored in an object due to its position, such as a book held above the ground.
What is potential energy
300
A solution with a pH of 3 is this type of substance and has a higher hydrogen ion concentration than pure water.
What is an acid?
300
Located roughly 15–35 km above Earth's surface, this atmospheric layer absorbs most of the sun's harmful ultraviolet radiation.
Ozone Layer
300
When presented with a large text to read, what is the best way to start the question?
Read the question and answer choices first.
400
movement of ions, and molecules across cell membranes without the need for energy input
Passive transport
400
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent
meiosis
400
These are the products of cellular respiration
Water, carbon dioxide, and ATP
400
When both alleles are present they will mix to create a new phenotype/trait
Incomplete dominance
400
A key to natural selection is that all organisms vary in their traits. This leads to some organisms having traits that are more beneficial in their environment, and therefore surviving to reproduce.
Why do organisms have variation in their phenotypic traits?
Random genetic mutations
400
According to this law, the pressure and volume of a gas are inversely proportional at constant temperature.
What is Boyle's Law?
400
This law states that the total mass of reactants must equal the total mass of products in a chemical reaction.
What is the Law of Conservation of Mass?
400
This greenhouse gas, produced by burning fossil fuels, is the primary driver of human-caused climate change.
What is carbon dioxide / CO₂?
400
At the end of a test, what is the best strategy to leave no answers blank?
Choose one letter and fill all blanks in
500
The minimum quantity of energy that is required to activate atoms or molecules to a condition in which they undergo a specified reaction.
Activation energy
500
The formula for photosynthesis

This phenomenon explains why a straw appears bent in a glass of water — the bending of light as it passes between media of different densities.
What is refraction?
500
This process, in which an atom loses electrons, always occurs alongside its counterpart, reduction.
What is oxidation?
500
This type of feedback loop occurs when Arctic ice melts, exposing darker ocean water that absorbs more heat, which causes even more ice to melt.

The first instinct cognitive bias causes students to second-guess a correct first instinct.
When should you change an answer despite instinct.
Only if you have a logical reason to do so
