◉ DNA.
Answer: Deoxyribonucleic acid: a long linear polymer found in the
nucleus of a cell and formed from nucleotides and shaped like a double
helix
◉ Emergent properties.
Answer: New properties that arise with each step upward in the
hierarchy of life, owing to the arrangement and interactions of parts as
complexity increases.
◉ Systems Biology.
Answer: An approach to studying biology that aims to model the
dynamic behavior of whole biological systems based on a study of the
interactions among the system's parts.
◉ Eukaryotic Cell.
Answer: A type of cell with a membrane-enclosed nucleus and
membrane-enclosed organelles. Organisms with eukaryotic cells
(protists, plants, fungi, and animals) are called eukaryotes.
◉ Prokaryotic Cell.
,Answer: A type of cell lacking a membrane-enclosed nucleus and
membrane-enclosed organelles. Organisms with prokaryotic cells
(bacteria and archaea) are called prokaryotes.
◉ Gene.
Answer: A discrete unit of hereditary information consisting of a
specific nucleotide sequence in DNA (or RNA, in some viruses).
◉ Gene expression.
Answer: The process by which information encoded in DNA directs the
synthesis of proteins or, in some cases, RNAs that are not translated into
proteins and instead function as RNAs.
◉ Genome.
Answer: The genetic material of an organism or virus; the complete
complement of an organism's or virus's genes along with its noncoding
nucleic acid sequences.
◉ Biosphere.
Answer: The entire portion of Earth inhabited by life; the sum of all the
planet's ecosystems.

Answer: All the organisms in a given area as well as the abiotic factors
with which they interact; one or more communities and the physical
environment around them
, ◉ Community.
Answer: All the organisms that inhabit a particular area; an assemblage
of populations of different species living close enough together for
potential interaction.
◉ Population.
Answer: A group of individuals of the same species that live in the same
area and interbreed, producing fertile offspring.
◉ Organism.
Answer: a creature such as a plant, animal or a single-celled life form, or
something that has interdependent parts and that is being compared to a
living creature
◉ Organs.
Answer: A specialized center of body function composed of several
different types of tissues.
