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 statements about genetics is true?

Differences among organisms reflect different nucleotide sequences in their DNA.

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

Fungi

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.

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

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

Which of the following statements regarding a common cellular activity is false?

New cells are derived from cellular components like organelles.

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

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 sweatshirt style. This prediction is an example of

a hypothesis

Which of the following best represents an example of technology?

Testing for genetic diseases

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.

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 and connection between form and function.

A hypothesis is

a tentative answer to some question.

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.

A theory is

an explanation of an idea that is broad in scope with multiple lines of evidence.

All organisms belonging to the kingdom Plantae

are photosynthetic and contain cells that are surrounded by cells walls with cellulose.

Members of the kingdom Animalia

can obtain their food by eating other organisms.

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.

Members of the kingdom Fungi

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

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.

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
