Biology Basics
This process occurs in plants to convert light energy into chemical energy, mainly in the chloroplasts.
What is photosynthesis?
This element has the atomic number 8 and is essential for cellular respiration in humans.
What is oxygen?
The energy stored in an object due to its position or configuration is called this.
What is potential energy?
This type of graph is used to display how a quantity changes over time, showing data points connected by straight lines.
What is a line graph?
The first step in the scientific method, involving background research and asking questions, is called this.
What is the observation or question?
These are the basic building blocks of proteins, linking together to form polypeptides.
What are amino acids?
The pH scale measures the acidity or basicity of a solution, and a pH value of 7 represents this.
What is neutral?
This law states that for every action, there is an equal and opposite reaction.
What is Newton’s Third Law of Motion?
The x-axis goes in this direction, while the y-axis goes in this direction.
What is horizontal and vertical?
This is a testable prediction, often based on prior knowledge or observation, that can be proven or disproven.
What is a hypothesis?
The process by which cells divide to form two identical daughter cells, often referred to as "mitosis" in somatic cells.
What is cell division?
This gas, produced by burning fossil fuels, contributes to the greenhouse effect.
What is carbon dioxide (CO2)?
This principle states that the velocity of an object decreases as its mass increases, assuming the force is constant.
What is Newton's Second Law of Motion?
In a scatter plot, this is the term used to describe a pattern where data points tend to follow a consistent upward or downward trend.
What is a correlation (positive or negative)?
In an experiment, this group is exposed to the factor being tested.
What is the experimental group?
This molecule carries genetic instructions from the DNA in a cell’s nucleus to the ribosomes.
What is messenger RNA (mRNA)?
This law states that matter cannot be created or destroyed in a chemical reaction.
What is the Law of Conservation of Mass?
This fundamental force is responsible for holding protons and neutrons together in the nucleus of an atom.
What is the strong nuclear force?
In a pie chart, if one slice represents 25%, this means that the data point for that slice is one-quarter of the total. This fraction is referred to as this.
What is a proportion?
This term refers to the variable that is measured and is expected to change as a result of the experiment.
What is the dependent variable?
This structure within a cell is responsible for producing energy in the form of ATP.
What is the mitochondrion?
This type of bond occurs when electrons are shared between atoms.
What is a covalent bond?
This is the formula used to calculate work done.
What is work = force × distance?
In a bar graph, if one of the bars is significantly taller than the others, this suggests that the value represented by that bar is this in comparison to the others.
What is an outlier?
The process of repeating an experiment to confirm results and ensure accuracy is called this.
What is replication?
