1)Which of the following is not a characteristic of all living organisms?

a.            Capable of self-reproduction

b.            Composed of multiple cells

c.             Complex yet organized

d.            Uses energy

2.            Place the following levels of biological organization in order from smallest to largest:

atom, biosphere, cell, ecosystem, molecule, organ, organism, population, tissue. Which is the smallest level capable of demonstrating all of the characteristics of life?

a.            atom, molecule, cells, tissue, organ, organism, population, ecosystem, an

 

biosphere.

b.            Cell

3.            Plants use the process of of photosynthesis to convert the energy in sunlight to chemical energy in the form of sugar. While doing so, they consume carbon dioxide and water and release oxygen. Explain how this process functions in both the cycling of chemical

nutrients and the flow of energy through an ecosystem.

Answer: Photosynthesis cycles nutrients by converting the carbon dioxide to sugar, which

 

is then consumed by other organisms. Additionally, the oxygen in water is released as

 

oxygen gas. Photosynthesis contributes to energy flow by converting sunlight to

 

chemical energy, which is then also consumed by other organisms, and by producing

 

heat.

4.            For each of the following organisms, match its description to its most likely doman

 

and/or kingdom:

a.            A foot-tall organism capable of producing its own food from sunlight.

b.            A microscopic, simple, nucleus-free organism found living in a riverbed

c.             An inch-tall organism growing on the forest floor that consumes material from

 

dead leaves.

d.            A thimble-sized organism that feeds on algae growing in a pond

1.            Bacteria

2.            Eukarya/Animalia

3.            Eukarya/Fungi

 

4.            Eukarya/Plantae

 

 

 

 

How does natural selection cause a population to become adapted to its environment over time?

 

 

 

 

6.            Which of the following statements best describes the logic of the scientific method?

 

 

a.            If I generate a testable hypothesis, tests and observations will support it.

 

 

b.            If my prediction is correct, it will lead to a testable hypotheses.

 

 

c.             If my observations are accurate, they will support my hypothesis.

 

 

d.            If my hypothesis is correct, I can expect certain test results

 

 

7.            Which of the following statements best distinguishes hypotheses from theories in science?

 

 

a.            Theories are hypotheses that have been proved.

 

 

b.            Hypotheses are tentative guesses; theories are correct answers to questions about

 

nature

 

 

c.               Hypotheses usually are narrow in scope; theories have broad explanatory power.

 

d.            Hypotheses and theories mean essentially the same thing in science.

 

 

8.                           is the core idea that unifies all areas of biology.

 

 

 

 

9.            Match each of the following terms to the phrase that best describes it.

 

 

a.            Natural selection.            1. A testable idea

 

 

b.            Evolution             2. Descent with modification

 

 

c.             Hypothesis         3. Unequal reproductive success

 

 

d.            Biosphere           4. All life-supporting environments on Earth
