Which is NOT a characteristic of all living organisms?
a. growth and development
b. composed of multiple cells
c. complex yet organized
d. uses energy - ✔✔B. (Because some living organisms are single celled.)
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? - ✔✔Atom,
molecule, cell, tissue, organ, organism, population, ecosystem, biosphere; the cell
Plants use the process 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.
- ✔✔Photosynthesis cycles nutrients by converting the carbon in 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.
How does natural selection cause a population to become adapted to its environment over time? -
✔✔On average, those individuals with inheritable traits best suited to the local environment produce
the greatest number of offspring that survive and reproduce. This increases the frequency of those traits
in the population over time. The result is the accumulation of evolutionary adaptations.
Which statement best describes the logic of the process of science?
a. If I generate a testable hypothesis, experiments and observations will support it.
b. If my prediction is correct, it will lead to a testable hypothesis
c. If my observations are accurate, they will support my hypothesis.
d. Test results may or may not support my hypothesis - ✔✔D.
, Which statement best distinguishes hypothesis from theories in science?
a. Theories are hypothesis that have been proven
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 and are supported by
a lot of evidence
d. Hypotheses and theories mean essentially the same thing in science - ✔✔C.
_________ is the core theme that unifies all areas of biology - ✔✔Evolution
What distinguishes a fact from an opinion? - ✔✔A fact should be confirmed to be the same by all
observers, whereas opinions can differ from one observer to the next.
Match each of the following terms to the phrase that best describes it.
a. Natural selection
b. Evolution
c. Hypothesis
d. biosphere
1. A testable idea
2. Descent with modification
3. Unequal reproductive success
4. All life supporting environments on earth - ✔✔A3; b2; c1; d4
Which major theme is evident?
By comparing genes between green sea turtles and humans, insight can be gained into how those genes
encode specific physical traits. - ✔✔Information flow: genes encode information to make proteins, which
then produce physics traits.
Which major theme is evident?
