Mrs.Gravett chapter 1 biology test "the science of Biology"

volume?

liters

The benefit of a scientist publishing in a peer-reviewed journal is the quality of the report will meet high _____________________________ standards.

scientific

When or why could this happen?

when new evidence is found out there

Can a theory be revised or replaced?

yes

The variable that is deliberately changed in an experiment?

independent or manipulated variable

data

information gathered during an experiment, collecting, recording, and analyzing

observation

involves the act of noticing and describing events or process in a careful orderly way. Scientist use observations to make inferences.

When sharing ideas through peer-reviewed articles, scientists reading the articles may come up with new questions to study. Does this help advance or harm science

advances

cell specialization

allows multicellular organisms cells to perform different functions.

inference

is a logical interpretation based in what scientist already know

hypothesis

is a scientific explanation for a set of observations that can bet tested in ways top support or reject it

controlled experiment

an experiment in which only one variable (the independent variable, or manipulated variable is changed)

science

is a way of gathering and analyzing evidence about the natural world

homeostasis

is the process by which organisms keep everything inside their bodies within a certain limit.

science is best described as a way of?

knowing

cells

are the smallest units that are considered to be alive

If a scientist proposed a hypothesis about a newly discovered organism and it's affect on humans, other scientists would design new expiriment to test the proposed __________________.?

hypothesis

controlled group

in an experiment , the group exposed to the same conditions as the experimental group except for one independent variable

the central themes/ Big Ideas in Biology

- cellular basis of life - evolution (change over time) - Information and heredity - Structure and function - matter and energy - unity and diversity of life - Growth, development and reproduction - interdependence of nature - homeostasis (steady state condition) - Science as a way of knowing

Some ways that science influences society include

- providing answers to some of society's practical problems - advancing technology that is useful to society, like computers. - increasing understanding of how people affect the environment

7.How many variables are tested in a controlled experiment?

1

When comparing a hypothesis to a theory: ______________________ (hypothesis or theory) unify a broad range of observations and ________________________ (hypothesis or theory) is a testable explanation for a set of observations.

1. theory 2. hypothesis

if you have 5L of water, how many milliliters do you have?

5,000mL

how many meters are in 6.7Km?

6,700 meters or (M)

temperature?

Celsius

Using a universal system of measurement is most important during which part of scientific methodology?

Collecting data

Biologists who work in the fields of genomics and molecular biology also study __________________.

DNA

A global ________________________ is a type of biologist who would likely use satellite technology

Ecologist

Bias

a point of view that is personal rather than scientific.

theory

a well tested explanation that unifies a broad range of observations and hypotheses and that enables scientist to make accurate predictions about new situations

______________________________ is considered a scientific attitude because it helps scientists come up with new & different experiments

creativity

The 4 attitudes shared by good scientist?

curiosity, open-mindedness, skepticism, creativity.

Quantitative

data that involves numbers

Qualitative

data that is descriptive

Understanding how science works will help you make better _________________________. This means that studying science can help you be a better member of society.

decisions

The variable that is observed and that changes in response to the independent variable?

dependent or responding variable

mass?

grams

A scientist working in the field of information and __________________ would most likely study DNA

heredity

length?

meters

A revised version of the original ___________ system is called ______ ______, an abbreviation for the System of International Units.

metric, S I

what are the smallest objects that biologists study?

molecules

Which characteristic of life would a food web represent?

need for material and energy

Can science answer all questions?

no

Can science define beauty?

no

Can science determine what is ethical?

no

Can science make opinions?

no

the work of a scientist begins with careful?

observations

Suppose a scientist studies new evidence that goes against ideas he/she already has. This scientist is showing which scientific attitude?

open-mindedness

During a peer-review, the reviewer checks?

oversights, unfair influences, fraud,mistakes, and bias

_________________________-reviewed journals are reviewed by anonymous and independent experts

peer

Society helps science advance by raising _________________________ that science can help answer.

questions

Which characteristic of life would a migrating bird represent?

respond to changes in their environment

A good scientist will not skip the peer-review process, even if he/she thinks they have discovered a great advancement in science, because other scientists will react with which scientific attitude?

skepticism

unlike or disciplines, such as history and the arts science relies on?

testing explanations

How many millimeters and cubic centimeters related (pg.24)?

they are equal units of measurement

The 3 main goals of science are?

~to investigate and understand the natural world. ~to provide a natural explanation for events in the natural world. ~to use explanations to make useful predictions about natural events.

the 8 characteristics of living things

• made up of cells • reproduce (sexual/asexual) • Based on a universal genetic code • Grow & develop • Obtain & use material & energy • respond to changes in their environment • Maintain a stable internal eviorment • As a group, change over time - evolution
