This is the basic unit of life in all living things.
What is a cell?
100
A trait that is passed from parent to offspring through DNA is called this.
What is an inherited trait?
100
This scientist is known as the father of genetics and discovered the basic principles of heredity through experiments with pea plants.
Who is Gregor Mendel?
100
This is the type of bond formed when electrons are shared between atoms.
What is a covalent bond?
100
Who proposed the evolution occurred through natural selection?
Charles Darwin
200
These two types of cells make up all living organisms: one has a nucleus, and one does not.
What are prokaryotic and eukaryotic cells?
200
Traits such as muscle strength from exercise or scars are this kind of trait, not passed through genes.
What are acquired traits?
200
These two scientists discovered the double-helix structure of DNA in 1953.
Who are James Watson and Francis Crick?
200
This type of bond forms when one atom gives up electrons to another atom, resulting in positive and negative ions.
What is an ionic bond?
200
What is an inherited trait that increases an organism's chances of survival.
Adaptation
300
This organelle is known as the "powerhouse" of the cell because it produces energy.
What is the mitochondrion?
300
If a child has one brown-eyed parent and one blue-eyed parent, and the child has brown eyes, brown is considered this type of allele.
What is a dominant allele?
300
This woman’s X-ray crystallography work was critical to the discovery of DNA’s structure, though she did not receive a Nobel Prize.
Who is Rosalind Franklin?
300
This weak bond forms between the slightly positive hydrogen atom of one molecule and the slightly negative atom of another, often in water.
What is a hydrogen bond?
300
What is the job of a species in an ecosystem.
Niche
400
This structure, shown in the image, is made of a phospholipid bilayer and controls what enters and exits the cell.
What is a cell membrane?
400
These are different forms of the same gene, such as the gene for eye color having a brown or blue version.
What are alleles?
400
This scientist developed a theory after observing species in the Galápagos Islands.
Who is Charles Darwin?
400
This type of covalent bond results when electrons are not shared equally, causing one end of the molecule to be slightly negative and the other to be slightly positive.
What is a polar covalent bond?
400
What term describes an organism's ability to survive and reperduce?
Fitness
500
This part of a plant cell helps maintain its shape and stores nutrients and waste.
What is the central vacuole?
500
A dominant allele results in the ability to roll your tongue. What is this type of trait inheritance called?
What is simple dominance (or Mendelian inheritance)?
500
These two scientists used a blender experiment to show that DNA, not protein, is the genetic material in viruses.
Who are Alfred Hershey and Martha Chase?
500
These types of interactions occur when molecules are close together and slightly attract each other due to temporary charges.
What are van der Waals forces?
500
Which scientist incorrectly proposed that traits acquired during life could be inherited?
Lamarick
