Are scavengers, feeding slowly by skimming up floating remains of fish

2

Life is organized in a hierarchical fashion. Which one of the following sequences illustrates that hierarchy as it increases in complexity?

Molecule, cell, tissue, organ, organ system, population, community, ecosystem

3

The tree in your backyard is home to two cardinals, a colony of ants, a wasp's nest, two squirrels, and millions of bacteria. Together, all of these organisms represent

A community

4

If you eat a hamburger, you're mainly eating ground up beef muscle. what levels of organization are represented in this ground up muscle?

Organism, population, and community

5

Which of the following statements about ecosystems is false?

Bacteria and fungi recycle energy within an ecosystem

6

The ultimate source of energy flowing into nearly all ecosystems is

Sunlight

7

A consumer eating a producer represents

A transfer of chemical nutrients and energy

8

Which of the following, if any, is not a common cellular activity?

a) cells respond to the environment
b) cells develop and maintain complex organization
c) cells take in and use energy
d) cells regulate their internal environment
e) all of the choices are common cellular activities

All of the choices are common cellular activities

9

The formation of systems typically results in the appearance of novel characteristics called

Emergent properties

10

Your instructor asks you to look into your microscope to see a prokaryotic cell. You will be looking for a cell that

Has a membrane

11

Which of the following is/are properties of life?

a) a complex organization
b) the ability to take in energy and use it
c) the ability to respond to stimuli from the environment
d) the ability to reproduce
e) all of the choices are correct

All of the choices

12

Which of the following statements is correct?
a) Genes are proteins that produce DNA
b) Each organism has its own unique DNA code
c) Differences among organisms reflect different nucleotide sequences in their DNA
d) Each DNA molecule is a single strand of nucleotides

Differences among organisms reflect different nucleotide sequences in their DNA

13

Which of the following is false? Living systems

a) are composed of two or more cells
b) maintain a relatively consistent internal environment
c) respond to changes in the environment
d) encode their genetic information in DNA
e) grow and develop

Are composed of two or more cells

14

Members of the Kingdom Animalia

Are composed of cells that lack a cell wall

15

Organisms that are not prokaryotes are in the domain

Eukarya

16

Which of the following is a kingdom within the Domain Eukarya?

Fungi

17

Organisms belonging to the Kingdom Plantae

are photosynthetic and contain cells that are surrounded by cell walls

18

Members of the Kingdom Fungi

include the mushrooms and yeasts, and decompose the remains of dead organisms and absorb nutrients from the leftovers

19

Which of the following statements is true of Domain Bacteria?

a) All bacteria are "animal-like" in that they eat other organisms
b) all bacteria have a membrane-bound nucleus
c) all bacteria are multicellular organsims
d) all bacteria lack a nucleus
e) all bacteria are "animal-like" in that they eat other organisms and all bacteria have a membrane-bound nucleus

All bacteria lack a nucleus

20

A scientist examining a group of cells under the microscope notices the presence of nuclei within these cells. Chemical tests reveal that each cell is surrounded by a wall composed of cellulose. These cells must come from an organism that is a member of the Kingdom

Plantae

21

Which of the following observations would provide the strongest evidence that the many different plants we call orchids are actually related to one another?

They all have the same common ancestor

22

The teeth of grain-eating animals (such as horses) are usually braod and ridged. This makes them suitable for grinding and chewing. Meat-eating animals (such as lions) have pointed teeth that are good for puncturing and ripping flesh. This illustrates

a result of natural selection and the connection between form and function

23

Which one of the following statements is not consistent with Darwin's mechanism of natural selection?

a) individuals in a population exhibit variations, some of which are heritable
b) individual organisms exhibit genetic change during their life spans to better fit their environment
c) factors in the environment result in some organisms with better reproductive success than others
d) natural selection is based in part on the overproduction of offspring
e) natural selection can lead to the appearance of new species

Individual organisms exhibit genetic change during their life spans to better fit their environment

24

Evolution by natural selection relies upon

a) heritable variation
b) overproduction of offspring
c) a struggle for existence
d) individual variation
e) all of the choices are correct

All of the choices are correct

to be more resistant to that antibiotic

26

Which of the following is/are true?

a) individuals evolve
b) organisms evolve structures because of need
c) evolution is deliberate and purposeful
d) evolution is a passive process
e) all of the choices are true

Evolution is a passive process

27

deductive reasoning

28

A hypothesis is

a tentative answer to some question

29

a) is the result of deductive reasoning
b) is a conclusion
c) can be tested
d) can be falsified
e) all of the choices are correct

all of the choices are correct

30

an example of a hypothesis

31

The role of a control in a experiment is to

provide a basis of comparison to the experimental group

32

To be scientifically valid, a hypothesis must be

testable and falsifiable
