Ch# 1 The Study of Life (STUDY Questions)

question

When Pasteur tested the hypothesis of spontaneous generation, he compared the ability of a sterilized growth medium (meat broth) to produce a population of bacteria in two different types of flasks. One had a simple neck open to the outside, and the other had a “goose neck” bend that also was open to the environment. Pasteur expected that bacteria would appear in the flask with the standard neck. In this experiment, the standard neck flask served as a/an:
answer

control.
question

The questions that can be answered by science are:
answer

limited by what can be investigated using the scientific method.
question

Because scientists are in the business of investigating nature, scientists function as:
answer

society’s eyes and ears on the natural world.
question

The liver releases glucose into the bloodstream if you don’t eat for a long time. This represents an example of a characteristic possessed by all living things. Which is it?
answer

maintaining a relatively constant internal environment
question

A scientific finding is believed to be true until new evidence arises. This view is referred to as:
answer

provisional assent.
question

Which of the following is a theory?
answer

There is molecular and biochemical evidence that all organisms are related
question

If you flip the light switch in your living room and nothing happens, what might be a good hypothesis to explain the absence of light?
answer

The circuit breaker for the living room might be the “off” position.
question

Imagine you’re a biology instructor lecturing to a group of students interested in ecology, the branch of biology that studies interactions between organisms and their environments. The students complain bitterly that they’re not interested in atoms and molecules because these are irrelevant to their interests. As a responsible instructor aiming to provide a complete and meaningful education, you would state:
answer

“You need to study atoms and molecules because the organization of life is hierarchical; this implies that, to understand the complex (ecology), you first need to understand the simpler underlying levels.”
question

The role of a control in an experiment is to:
answer

provide a basis of comparison to an experimental group.
question

What is the difference between a tissue and an organ system?
answer

An organ system includes tissues.
question

A good hypothesis must:
answer

be falsifiable.
question

Organelles are:
answer

like tiny organs within cells.
question

Evolution allows us to explain:
answer

both the diversity of life and how all living things are related.
question

Tissues are grouped together in functional units called:
answer

organs.
question

Which scientist disproved the theory of spontaneous generation?
answer

Pasteur

Science presents society with ________, about which society then makes decisions.
answer

question

Which of the following is the most complex level of organization?
answer

question

A tree in your backyard is home to robins, squirrels, beetles, and lichens. Together all these organisms compose a/an:
answer

community
question

Which of the following is the correct order of complexity, going from least to most complex?
answer

atom, molecule, organelle, cell, tissue, organ
question

We use the scientific method every day. Imagine your car doesn’t start one morning before school. Which of these is a reasonable hypothesis regarding the problem?
answer

I’m out of gas.
question

Which of the following is true?
answer

A scientific theory explains what we know to this date about a natural event.
question

The difference between a theory and a hypothesis is that a:
answer

theory must be supported by evidence.
question

Which one of the following is true about scientific knowledge?
answer

Scientific knowledge is not absolute, because the possibility is always held open that new experiments may one day prove it wrong.
question

Which of the following is an example of how living things assimilate energy?
answer

eating a meal
question

What invention by Bell Labs in 1947 brought about modern electronics?
answer

the invention of the transistor
question

A scientific explanation that is tentative and requires more investigation is termed a/an:
answer

hypothesis.
question

Biology developed as a science later than physics because:
answer

the living world is tremendously diverse compared to the non-living world.
question

Living things inherit information from their parents encoded in:
answer

DNA.
question

Which of the following is at the root cause for all cancers?
answer

a breakdown of the cell division process
