Already Graded A+
biology - 🧠 ANSWER ✔✔The study of all aspects of life and living things.
organism - 🧠 ANSWER ✔✔An individual living thing.
cell - 🧠 ANSWER ✔✔The smallest unit of life, consisting, at a minimum, of
an outer membrane that encloses a watery medium containing organic
molecules, including genetic material composed of DNA.
unicellular - 🧠 ANSWER ✔✔Single-celled; most members of the domains
Bacteria and Archaea and the kingdom Protista.
,multicellular - 🧠 ANSWER ✔✔Many-celled; most members of the kingdoms
Fungi, Plantae, and Animalia with intimate cooperation among cells.
photosynthesis - 🧠 ANSWER ✔✔The complete series of chemical reactions
in which the energy of light is used to synthesize high-energy organic
molecules, usually carbohydrates, from low-energy inorganic molecules,
usually carbon dioxide and water.
homeostasis - 🧠 ANSWER ✔✔The maintenance of the relatively constant
internal environment that is required for the optimal functioning of cells.
deoxyribonucleic acid (DNA) - 🧠 ANSWER ✔✔A molecule composed of
deoxyribose nucleotides; contains the genetic information of all living cells.
evolution - 🧠 ANSWER ✔✔The descent of modern organisms, with
modification, from preexisting life-forms
evolution - 🧠 ANSWER ✔✔The theory that all organisms are related by
common ancestry and have changed over time.
evolution - 🧠 ANSWER ✔✔Any change in the genetic makeup (the
proportions of different genotypes) of a population from one generation to
the next.
,population - 🧠 ANSWER ✔✔All the members of a particular species within
a defined area, found in the same time and place and actually or potentially
interbreeding.
gene - 🧠 ANSWER ✔✔The unit of heredity; a segment of DNA located at a
particular place on a chromosome that usually encodes the information for
the amino acid sequence of a protein and, hence, a particular trait.
mutation - 🧠 ANSWER ✔✔A change in the base sequence of DNA in a
gene; often used to refer to a genetic change that is significant enough to
alter the appearance or function of the organism.
natural selection - 🧠 ANSWER ✔✔Unequal survival and reproduction of
organisms due to heritable differences in their phenotypes, with the result
that better adapted phenotypes become more common in the population.
adaptation - 🧠 ANSWER ✔✔A trait that increases the ability of an individual
to survive and reproduce compared to individuals without the trait.
species - 🧠 ANSWER ✔✔The basic unit of taxonomic classification,
consisting of a population or group of populations that evolves separately
from other populations. In sexually reproducing organisms, a species can
be defined as a population or group of populations whose members

, interbreed freely with one another under natural conditions but do not
interbreed with members of other populations.
extinction - 🧠 ANSWER ✔✔The death of all members of a species.
element - 🧠 ANSWER ✔✔A substance that cannot be broken down, or
converted, to a simpler substance by ordinary chemical reactions.
atom - 🧠 ANSWER ✔✔The smallest unit of an element that retains the
properties of the element.
molecule - 🧠 ANSWER ✔✔A particle composed of one or more atoms held
together by chemical bonds; the smallest particle of a compound that
displays all the properties of that compound.
tissue - 🧠 ANSWER ✔✔A group of (normally similar) cells that together
carry out a specific function; may also include extracellular material
produced by its cells.
organ - 🧠 ANSWER ✔✔A structure (such as the liver, kidney, or skin)
composed of two or more distinct tissue types that function together.
organ system - 🧠 ANSWER ✔✔Two or more organs that work together to
perform a specific function; for example, the digestive system.
