1-15: Fill-in-the-Blank with the best possible answer.
1. The cell is the smallest unit that can perform the basic activities of life.
2. An individual form of life that uses energy to carry out the activities of life is an organism.
3. List three characteristics of a prokaryotic cell:
a. No organelles
b. Genetic material is in the cytoplasm (no nucleus).
c. Found in most unicellular organisms (bacteria, etc).
4. Organisms that have cells with a nucleus are in the domain Eukarya.
5. All cells come from existing (living) cells.
6. The end result of mitosis is two genetically identical daughter cells.
7. What is the main purpose of mitosis? To divide the nucleus.
8. An allele that is expressed even if only one copy is present is a genotype is a dominant allele.
9. Dwarf corn plants (ff) are crossed with corn plants or regular height (FF). What will the first
generation of plants look like? (hint draw a punnet square)
Answer: 4 Regular Height Corn Plants
10. A Punnet Square shows how alleles might combine.
11. One parent has one dominant allele for tongue rolling (T) and one for no tongue rolling (t). The
other parent has a tt genotype. What is the probability of the offspring being able to roll their
tongue?
Answer: 50%
12. Organisms began living on Earth 3.8 billion years ago. Then 1.2 billion years ago, multicellualr
organisms evolved.
13. Scientists determine the relative age of a fossil by comparing it with fossils found in other rock
layers.
14. Lamarck believed that the fossil record showed that species evolved over time.
15. The genes of two closely related organisms will be very similar.

27-36: True/False If the statement is true, write true on the line. If the statement is false, change
the underlined term to make the statement true.
True

live to adulthood. This is an example of isolation.
False-Natural Selection
29. Finches two separate island have different shaped beaks. This is a
result of sexual reproduction.

to form a new cell.
True
35. DNA stores information as genes made up of nucleotides.
True
36. Pure nitrogen must be fixed before it can be used by plants.
37-55: Fill in the blank with the best possible answer
37. Ecology is the study of how organisms interact with eachother and their environment.
38. Nonliving parts of an ecosystem include temperature, light, soil, and water.
39. Describe the difference between a food chain and food web. A food chain shows one feeding
relationship and a food web shows many interlocking feeding relationships.
40. A producer is an organism that captures energy and stores food as chemical energy.
An example of a producer is moss.
41. Both consumers and producers are a source of food for decomposers.
42. Label the following energy pyramid with what level has the most energy and what level has the
least amount of energy.
43. Put the following terms in correct order from simplest to most complex: Ecosystem, Community,
Biome, Organism, Population
Organism, Population, Community, Ecosystem, Biome
44. Interactions that benefit one species and does not benefit or harm the other species is
commensalism.
Name ______________________________ Date __________________ Pd __________
45. Grazing in a herd benefits a buffalo population because it gives them increased protection from
predators.
46. Each species has a different role, or niche, in an ecosystem.
47. Competition is the struggle between individuals or different populations for a limited resource.
An example of competition is Creosote bushes release chemicals into soil to prevent other
plants from putting out roots.
48. The biome that receives the most rain fall each year is the tropical forest.
49. A gradual change in an area’s community is called succession.
50. Explain the term carrying capacity. The maximum number of individuals that an ecosystem can
support.
51. Define natural resource. Any type of material or energy that humans use to meet their needs.
52. Would the population density be greater in a city or suburbs? Why?
Population density is greater in a city than in suburbs because there are more people in a
smaller place.
53. Name 3 renewable resources.
Trees, Sunlight, Water
54. Name 3 nonrenewable resources.
Oil, Coal, Petroleum
55. Define conservation. The process of saving or protecting a natural resource.
Describe sustainable practices. Ways of living and doing business that use natural resources
without using them up. (i.e. Developing new technologies, reducing resource use, and creating
less waste)
