Identical twin girls are separated at birth and cared for by two different families. After twenty years, the twins have different heights and weights. What is most likely the cause of these differences?

• One twin had a genetic condition that prevented her from growing tall.
• The DNA of one twin was different from the DNA of the other twin.
• Each twin was provided a different diet and physical activities.
• The proteins made by one twin were different than the proteins made by the other twin.

Back

Each twin was provided a different diet and physical activities.

Front

Which statement best describes natural selection?

• As the weather changes, organisms that are able to find shelter need less energy to live.
• Organisms that eat only plants need less food than organisms that eat animals.
• Organisms better adapted to their environment are more likely to reproduce and pass on their traits to their offspring.
• Small organisms are more likely to survive than larger organisms.

Back

Organisms better adapted to their environment are more likely to reproduce and pass on their traits to their offspring.
