Chapter 1 Test Flashcards
in an experiment, what group receives no experimental treatment
control group
Give 2 characteristics of living things
evolution,growth
species
similar organisms that can reproduce and make fertile offspring
chemical reactions that take place in an organism are called
biochemical reactions
the variable that is changed during an experiment is the
independent
A change in inherited traits over time is
evolution
all living things and the places where they are found make up the
biosphere
what is it called when living things respond to maintaining internal body temperature
maintaining homeostasis
what are 2 things organisms use energy for
growth, move
difference between growth and development
growth is getting larger, development is becoming more complex
example of structure and function being related in biology
Structure determines function
what types of organisms undergo photosynthesis
plants
basic unit of life
cells
an educated guess
hypothesis
becoming more complex
development
act of noting or perceiving objects
observation
2 examples of an organism
predatory, individual
what do we use to make observations
senses
first step in the scientific process
make an observation
why does an organism respond to its environment
to improve their chances of survival and reproduction
a hypothesis can be
proposed explanation
how many variables should change in an experiment
only 1
give an example of homeostasis
Regulating body temperature
What is natural selection
Species adapting to their environment
what type of organisms does cellular respiration take place in
Autotrophic & heterotrophic
what does biology mean
The study of Life
What is interdependence
one relies on each other
As organisms develop, they are usually gaining the ability to
preform complex functions, and adapt to their environment
What branch of biology studies interdependence
ecology
Why do we look like our parents
Genetics
what is the original source of energy
sunlight
a scientist forms a ___ to summarize his results
theory
What is the process where living things have the next generation of offspring
reproduction
what is a planned procedure to test a hypothesis
experiment
data that involves numbers or measurments
Quantitative data
can theories change over time
yes, different outcomes of a test
what codes the traits that people inherit
genetics
give an example of an organism responding to its environment
flower opening in the sunlight
members of the same __ can breed and produce offspring
species
example of system in bio
circulatory
the variable that changes as a result of the manipulated variable
dependent
