Mitochondria
During the Industrial Revolution in Britain, many new factories were built which released dark clouds of smoke into the air. Dark grey moths survived attacks by birds more often than their light grey neighbors. Over time, light grey moths disappeared from the area. This change in population is an example of _____________
Natural Selection
If your genotype is Aa, will you show the dominant or the recessive trait?
Dominant
True or false: all the cells in your body have exactly the same DNA
True
Which of the following best describes the cardiovascular system? This system….
a. Allows the heart, blood, and blood vessels to work together
b. Consists of nerves and specialized cells known as neurons
c. Consists of the lungs, which take in oxygen and expel carbon dioxide
d. Allows the brain to function as a main part of the body
A
This organelle protects the cell because it controls what goes in and out of the cell. It is sometimes thought of as the security guard. EVERY cell has one.

False
What is it called when there is a mistake that is made in your DNA?
Mutation
How do the cardiovascular and respiratory systems work together?
The respiratory system gets oxygen from the air and the cardiovascular system delivers that oxygen to your cells
This is the gel-like substance that surrounds each of the organelles inside the cell.
Cytosol
A particular environment is becoming warmer over time due to rises in Carbon Dioxide produced by humans. There are currently 2 species of rabbit: one with thick dark fur and one with thin light fur. How would the rabbit population be impacted by environmental change?
The dark thick fur rabbits would decrease in population and the thin light fur rabbits would increase in population
True or false: in a family of a mother, father, and several children, you can expect every child to have ALL of the mother's DNA and ALL of the father's DNA
False
What is the shape of a DNA molecule?
Double helix
What two body systems are most useful in getting nutrients from food you eat to your brain?
Digestive and cardiovascular
This cell organelle makes proteins and can be found on the rough ER or free floating in the cell.
Ribosomes
During the Industrial Revolution in Britain, many new factories were built which released dark clouds of smoke into the air. Dark grey moths survived attacks by birds more often than their light grey neighbors. Over time, light grey moths disappeared from the area. What would happen if the pollution decreased and the trees became light again?
More light moths would survive and the number of dark moths would decrease
