How are mutations and cancer related?
A. Mutations always make cells stronger and more resistant to disease
B. Mutations help cells grow in a controlled and healthy way
C. Mutations can cause cells to grow uncontrollably, which can lead to cancer
D. Mutations destroy all the DNA in a cell, causing it to die immediately

What is the relationship between cancer and homeostasis?
A. Cancer helps the body maintain homeostasis by speeding up cell repair
B. Cancer improves the balance of organ systems in the body
C. Cancer disrupts homeostasis by causing uncontrolled cell grow

What is the main difference between weather and climate?
A. Weather is short-term atmospheric conditions, while climate is the long-term average of weather patterns
B. Weather and climate are the same, just used in different seasons
C. Climate changes every day, but weather stays the same for years
D. Weather only happens during storms, while climate is calm
Weather is short-term atmospheric conditions, while climate is the long-term average of weather patterns
How could a mutation affect the digestive system?
A. It would improve the speed of digestion by making enzymes faster
B. It would only change the color of digestive organs, not their function
C. It could help the body absorb more nutrients than usual
D. It might change a protein needed to break down food, making digestion less effective
It might change a protein needed to break down food, making digestion less effective
What is the correct order of central dogma?
DNA--?RNA-->protein
How is living in social groups an evolutionary success for some species?
A. It forces every member to survive completely on their own
B. It increases survival by allowing cooperation in finding food, avoiding predators, and raising offspring
C. It leads to fewer individuals in the population over time
D. It stops species from needing to adapt to their environment
It increases survival by allowing cooperation in finding food, avoiding predators, and raising offspring
What is the greenhouse effect?
A. The process of plants growing faster due to heat and sunlight
B. The trapping of heat by gases in Earth’s atmosphere, keeping the planet warm
C. The Earth cooling down because of too much ice at the poles
D. The release of oxygen by trees into the atmosphere
The trapping of heat by gases in Earth’s atmosphere, keeping the planet warm
How do feedback mechanisms help maintain homeostasis in the body?
A. They detect changes in the internal environment and trigger responses to return the body to balance
B. They make all body systems shut down during stress
C. They prevent the body from responding to external changes
D. They increase the heart rate at all times to keep the body alert
They detect changes in the internal environment and trigger responses to return the body to balance
Why would two people get genetic testing before having children?
to see if they may be carriers of a genetic condition
What is the main difference between natural selection and genetic drift?
A. Natural selection happens by chance, while genetic drift is based on survival
B. Natural selection only occurs when mutations happen
C. Natural selection is caused by environmental pressures, while genetic drift happens due to random chance
D. Genetic drift only occurs in large populations, while natural selection does not
Natural selection is caused by environmental pressures, while genetic drift happens due to random chance

C. To prevent all natural changes in ecosystems
D. To increase pollution and speed up resource use
To protect the environment and make sure future generations have the resources they need
