Which of the following statements about the domain Bacteria is true?
All bacteria lack a nucleus.
Which of the following statements about the properties of life is false?
All organisms have the ability to maintain a constant internal temperature.
What is the difference between a tissue and an organ system?
An organ system includes tissues.
Organisms that are prokaryotes are in the domains
Bacteria and Archaea.
Which of the following statements about ecosystems is false?
Bacteria and fungi recycle energy within an ecosystem.
Which of the following is not an example of evolution that has resulted from human activity?
Because of hunting, species such as bears and wolves are in danger of extinction.
Members of the kingdom Animalia
Can obtain their food by eating other organisms.
Which of the following best represents an example of technology?
Developing a test for genetic diseases
Which of the following statements about genetics is true?
Differences among organisms reflect different nucleotide sequences in their DNA.
Which of the following statements about evolution is true?
Evolution can result in adaptations.
Which of the following is a kingdom within the domain Eukarya?
Fungi
You notice that over the past month, many students on campus have started wearing a new style of school sweatshirt. You think to yourself that perhaps the bookstore has recently started selling this new sweatshirt style. This prediction is an example of
Hypothesis
Which of the following statements is not consistent with Darwin's theory of natural selection?
Individual organisms exhibit genetic change during their life spans to better fit their environment.
Which of the following statements regarding a common cellular activity is false?
New cells are derived from cellular components like organelles.
The role of a control in an experiment is to
Provide a basis of comparison to the experimental group.
The ultimate source of energy flowing into nearly all ecosystems is
Sunlight
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.
A hypothesis is
a proposed explanation for a set of observations.
The teeth of grain-eating animals (such as horses) are usually broad and ridged. This makes the teeth 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 as well as the connection between form and function.
A theory is
an explanation of an idea that is broad in scope and supported by a large body of evidence.
All organisms belonging to the kingdom Plantae
are photosynthetic.
Consider the following statement: "If all vertebrates have backbones, and turtles are vertebrates, then turtles have backbones." This statement is an example of
deductive reasoning.
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.
Life is organized in a hierarchical fashion. Which of the following sequences correctly lists that hierarchy from least inclusive to most inclusive?
molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem
If you eat a hamburger, you are mainly eating ground-up beef muscle. What levels of organization are represented in this ground-up muscle?
organelle, cell, and tissue
To be scientifically valid, a hypothesis must be
testable and falsifiable.
Kingdom Fungi includes species
that obtain food by decomposing dead organisms and absorbing the nutrients.
An antibiotic kills 99.9% of a bacterial population. You would expect the next generation of bacteria
to be more resistant to that antibiotic.
A scientist performs a controlled experiment. This means that
two experiments are conducted, one differing from the other by only a single variable.
In an ecosystem, energy
typically flows from producers through a series of consumers.
