2025/2026 ALL ANSWERS CORRECT VERIFIED AND
GRADED A+,BEST FOR BIOLOGY


Evolution - CORRECT ANSWERS Evolution is the process of change that has
transformed life on Earth


DNA - CORRECT ANSWERS Deoxyribonucleic acid: a long linear polymer found
in the nucleus of a cell and formed from nucleotides and shaped like a double
helix


Biology - CORRECT ANSWERS The scientific study of life


Eukaryotic Cell - CORRECT ANSWERS 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 - CORRECT ANSWERS A type of cell lacking a membrane-
enclosed nucleus and membrane-enclosed organelles. Organisms with
prokaryotic cells (bacteria and archaea) are called prokaryotes.


Biosphere - CORRECT ANSWERS The entire portion of Earth inhabited by life;
the sum of all the planet's ecosystems.


Ecosystems - CORRECT ANSWERS 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 - CORRECT ANSWERS All the organisms that inhabit a particular
area; an assemblage of populations of different species living close enough
together for potential interaction.


Population - CORRECT ANSWERS A group of individuals of the same species
that live in the same area and interbreed, producing fertile offspring.


Organism - CORRECT ANSWERS 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 - CORRECT ANSWERS A specialized center of body function composed
of several different types of tissues.


Organ Systems - CORRECT ANSWERS A group of organs that work together in
performing vital body functions.


Tissues - CORRECT ANSWERS An integrated group of cells with a common
structure, function, or both.


Organelles - CORRECT ANSWERS Any of several membrane-enclosed
structures with specialized functions, suspended in the cytosol of eukaryotic
cells.


Cell - CORRECT ANSWERS The part of a neuron that houses the nucleus and
most other organelles.


Molecule - CORRECT ANSWERS Two or more atoms held together by covalent
bonds.


Negative Feedback - CORRECT ANSWERS A form of regulation in which
accumulation of an end product of a process slows the process; in physiology, a

,primary mechanism of homeostasis, whereby a change in a variable triggers a
response that counteracts the initial change.


Positive Feedback - CORRECT ANSWERS A form of regulation in which an end
product of a process speeds up that process; in physiology, a control
mechanism in which a change in a variable triggers a response that reinforces
or amplifies the change.


Adaptation - CORRECT ANSWERS Inherited characteristic of an organism that
enhances its survival and reproduction in a specific environment.
