BIO 151 EXAM 1 EXAM WITH CORRECT
QUESTIONS AND ANSWERS 2025
Emergent properties - CORRECT-ANSWERSIt's the property where living things
become more and more complex as it goes from cellular level (exp humans are made of
cells) to organ system (exp humans are made of organ system composed of millions of
cells).
Cell ---> Tissue ----> Organ ---> Organ System ---> Animal
Biology - CORRECT-ANSWERSScientific study of life.
Molecule - CORRECT-ANSWERSis an electrically neutral group of two or more atoms
held together by chemical bonds.
Organelle - CORRECT-ANSWERSis a specialized subunit within a cell that has a
specific function, and it is usually separately enclosed within its own lipid bilayer.
Cell - CORRECT-ANSWERSthe smallest structural and functional unit of an organism,
typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
Microscopic organisms typically consist of a single cell, which is either eukaryotic or
prokaryotic.
Tissue - CORRECT-ANSWERSany of the distinct types of material of which animals or
plants are made, consisting of specialized cells and their products.
Organ - CORRECT-ANSWERSis a collection of tissues joined in a structural unit to
serve a common function.
Organism - CORRECT-ANSWERSis any contiguous living system (such as animal,
fungus, micro-organism, or plant).
, Population - CORRECT-ANSWERSis a summation of all the organisms of the same
group or species, who live in the same geographical area, and have the capability of
interbreeding.
Community - CORRECT-ANSWERSAll of the groups of animals or plants living
together in the same area or environment and usually interacting to some degree.
Ecosystem - CORRECT-ANSWERSis a community of living organisms (plants, animals
and microbes) in conjunction with the nonliving components of their environment (things
like air, water and mineral soil), interacting as a system.
Biosphere - CORRECT-ANSWERSThe entire population of Earth inhabited by life; the
sum of all the planet's ecosystems.
Eukaryotic cell - CORRECT-ANSWERSA type of cell with a membrane-enclosed
nucleus and membrane-enclosed organelles.
Prokaryotic cell - CORRECT-ANSWERSA type of cell lacking a membrane-enclosed
nucleus and membrane-enclosed organelles.
Matter - CORRECT-ANSWERSAnything that takes up space and has mass.
Element - CORRECT-ANSWERSAny substance that cannot be broken down to any
other substance by chemical reactions.
Compound - CORRECT-ANSWERSA substance consisting of two or more different
elements combined in a fixed ratio.
Atom - CORRECT-ANSWERSThe smallest unit of matter that retains the properties of
an element.
Proton - CORRECT-ANSWERSA subatomic particle with a single positive electrical
charge. It is found in the nucleus of an atom.
