semester 1 exam part 1 Flashcards
to maintain their internal organization, all living things must have a constant supply of
energy
reproduction involves the transfer of genetic information from
parents to offspring
the stable internal environment maintained by living things is called
homeostasis
the most important driving force in evolution is
natural selection
the scientific process that involves using the five senses is
observation
data that are quantitative are always
represented by numbers
a hypothesis is a statement that
can be tested
a broad and comprehensive statement of what is believed to be true is a
theory
a small part used to represent an entire population is called a
sample
all organisms possess DNA. DNA
contains info for growth and development
instructions for development that are passed from parents to offspring are known as
genes
as a characteristic of all living things, homeostasis relates most directly to which of the following biological themes
stability
ecology
is the study of communities or organisms in relation to their environment.
which of the following is a means by which heterotrophs can obtain energy
consuming autotrophs
not necessarily a distinct property of living things
complexity
the smallest units that can carry on all the function of life are called
cells
as the cells in a multicellular organism multiply, they become different from each other in a process called
differentiation
the sum of all of the chemical processes that occur in an organism is called
metabolism
cells and groups of cells are organized by their
function
biology is the study of
all living things
growth occurs by
cell division and enlargement
simplest part of an element
atom
gain of an electron
reduction
a pure substance composed of tow or more elements
compound
particle composed of one or more atoms
molecule
loss of an electron
oxidation
pure substance that cannot be broken down
element
monomer of nucleic acids
nucleotide
breaks large molecules into smaller ones
hydrolysis
monomer of proteins
amino acids
