Q

What make science different from other human activities?

A

It deals only with the natural world.
Scientists collect and organize information in an orderly way, looking for patterns and connections among events.
Sciences proposes explanations that are based on evidence, and that can be tested with more evidence

Q

What does a reviewer do

A

He or she looks for oversights, Unfair influences, fraud, or mistakes in techniques of rasping. He certifies that the work meets the standards set by the scientific community.

31
Q

Theory in science

A

A well tested explanation that unifies a broad range of observations and hypothesis and that enable scientist to make accurate predictions about new situations.

32
Q

What is the difference between a law and a scientific theory?

A

A law is description of how some aspects of the natural world are expected to behave in certain situations and a theory is more dynamic and complex since it encompasses a greater number of hypotheses and are in constant change.

33
Q

Using science involves …

A

Understanding its context in society and its limitations.

34
Q

Can science answer ethical or moral questions?

A

No, since the scientific explanations involve only the natural world (it cannot tell us if, for example, a new technology should be used, it can only tell us how)

35
Q

Bias

A

Particularly preferences or points of view that are personal rather than scientific. Ex: personal taste, preferences, standard of beauty, etc.

36
Q

Can bias affect science?

A

Yes, since they can lead to the misinterpretation or misapplication of scientific data to prove a scientist’s particular point.

37
Q

Is it important to understand how science works?

A

Yes

38
Q

Is it important to appreciate the power and limitations of science?

A

Yes.

39
Q

Biology

A

Study of life

40
Q

Can things exist at the border between living an non living things?

A

Yes. Ex: viruses

41
Q

Characteristics that most living things have

A
  • made up of cells.

  • obtain an use materials and energy
  • grow and develop
  • reproduce
  • respond to their environment
  • maintain a stable internal environment
  • change over time.
42
Q

All living things sore the complex information that they need to reproduce, live and growth in a ___________ which is written in the _____

A

Genetic code, DNA

43
Q

Is the information copied and pass from parent to offspring?

A

Yes

44
Q

Is life’s genetic code almost identical in every organism on Earth?

A

Yes

45
Q

Does every organism have a participle patter of growth and development?

A

Yes

46
Q

Condition in which the internal environment is stable even when the external conditions change dramatically.

50
Q

Molecular

58
Q

All organisms are…

A

Are composed of a common set of carbon-based molecules, sore information in a common genetic code and use proteins to buil their structure and carry out their functions.

59
Q

Biosphere

A

Living planet

60

Interdependent relationships between organism and the environment that surrounds them depend on …

A

The cycling of matter and the flow of energy.

61
Q

Th job of science is …

A

To use observations, questions and experiments to explain he natural world in terms of natural force and events. All of this enables us to take actions that affect events in the world around us.

62
Q

Biology includes …

A

Many overlapping fields that use different tools to study life from the level of molecules to the entire planet.

63
Q

Global ecology studies

A

The global impact that we have and its effects on all the life on earth.

64
Q

Biotechnology

A

Field based on our ability to edit and rewrite the genetic code. It raises enormous ethical, legal, and social questions.

65
Q

Tree of life

A

Work of various biologist which wish to create a universal tree of life which contains all the relationships between species.

66
Q

Ecology and evolution of infectious diseases

A

We need to undertake the interactions that occur in the biosphere to be able to create cures for viruses that evolved in animals and that affect us.

67
Q

Genomics and Molecular Biology

A

Focus on the studies of DNA and other molecules inside cells.

68
Q

Genomics is looking …

A

At the entire sets of DMA code contained in a wide range of organisms.

69
Q

Scientist rely on ________________ when conducting studies.

A

A common system of measurement and safety procedures.

70
Q

Why do most scientist use the metric system to collect data and while performing experiments?

A

Because researchers need to be able to replicate one another’s experiments, and because most of this involve gathering quantitative data.

71
