TERM 2
cells contain _, which is the _ info
that
DEFINITION 2
DNA, heritable
TERM 3
DNA is
DEFINITION 3
the substance of genes
TERM 4
Genes
DEFINITION 4
the units of inheritance that transmit info from parent to
offspring
TERM 5
At what point does life start?
DEFINITION 5
Life doesn't "start" because it never "stopped".
Something is considered living if it has _
intermediary metabolism
TERM 7
intermediary metabolism
DEFINITION 7

something is "living"
TERM 8

DEFINITION 8
cellular!
TERM 9
haploid condition
DEFINITION 9
an individual sperm or egg cell
TERM 10
Structure of DNA
DEFINITION 10
each DNA molecule is made up of 2 long chains arranged in a
double helix. Each link of the chain is one of four kinds of
chemical building blocks called NUCLEOTIDES
System
a combination of components that form a more complex
organization
TERM 17
What are 3 examples of biological
systems?
DEFINITION 17
cells, organisms and ecosystems
TERM 18
emergent properties result from
DEFINITION 18
arrangements and interactions within a system
TERM 19
_ _ emerge with each step upward in the
hierarchy of _ _.
DEFINITION 19
new properties, biological order
TERM 20
What is the biological hierarchy, from lowest
to highest?
DEFINITION 20
At the lowest level are atoms that are ordered into complex
biological molecules. Biological molecules are organized into
structures called organelles, the components of cells. Cells
are the fundamental unit of structure and function of living
things.
What four functions must all organisms
accomplish?
uptake and processing of nutrients, excretion of wastes,
response to environmental stimuli, and reproduction
TERM 22
A localized group of organisms that belong to
the same species is called a
DEFINITION 22
population
TERM 23
Organisms interact with their environments,
exchanging matter and energy. For example,
plant chloroplasts convert the energy of
sunlight into
DEFINITION 23
the potential energy of chemical bonds
TERM 24
The main source of energy for producers in an
ecosystem is
DEFINITION 24
light energy
TERM 25
Which of the following types of cells utilize
deoxyribonucleic acid (DNA) as their genetic
material but do not have their DNA encased
within a nuclear envelope?
DEFINITION 25
C) archaea
