Cells
Structures in the nucleus that contain an organism's genetic information
What are chromosomes?
What is another name for the windpipe?
What is the trachea?
Sometimes found in the nucleus, sometimes found floating around in a cell.
What is DNA (deoxyribonucleic acid)?
The best definition for evolution
What is descent with modification?
Also known as the urinary system, this system helps you pee.
What is the excretory system?
Organelles in which sugar is made during photosynthesis
What are chloroplasts?
What is skeletal, cardiac, and smooth muscle?
Structures where genes are located.
What are chromosomes?
Evolutionary biologists create these visuals after researching relationships between species.
What are branching diagrams?
This structure controls what enters and exits a cell.
What is the cell membrane?
The invention that helped prove cell theory
What is a microscope?
The thin outer layer of skin covering the body.
What is the epidermis?
Name the two types of traits
What are acquired and inherited traits?
We utilize this to make the geologic time scale and to know the history of the earth, including past species and when they lived.
What is the fossil record?
This principle of natural selection can be seen in this example:
Some bacteria are resistant to antibiotics.
What is "genetic variation"?
These organelles store nutrients and waste. Both plant and animal cells have them.
What are vacuoles?
Your mood, hunger, and sleep are all regulated by this.
What are Hormones (the endocrine system)?
The number of chromosomes a human has
What is 46 (or 23 pairs of) chromosomes?
Two species have a recent common ancestor if they share this
What is a homologous structure?
This organelle converts oxygen and nutrients into adenosine triphosphate (ATP)- the energy that powers the cell's activities.
This type of organism has specialized cells
What are multicellular organisms?
How does the skeletal system help out the circulatory system?
Bones produce blood cells and the rib cage protects the heart
This causes variation among a species
What are mutations?
This person is known as the father of evolution
Analogous structures support evolutionary relationships because they show this...
What are adaptations? (Analogous structures show that organisms developed similar traits that serve similar functions because they live in, and are suited to, similar environments)
