,Biology - Answer: the scientific study of life
Cell Biologist - Answer: studies the structure of cells to learn how they function and interact with
chemical and physical factors/research the causes of cancers.
Ecologists - Answer: Are biologists who specialize in studying the way that living organisms interact with
their environments.
Astrobiologists - Answer: who study conditions on other planets and design experiments to determine
whether or not life could exist in other places in our solar system.
Atoms are - Answer: Building blocks of matter
Biomolecules - Answer: are the "Legos" used to build the structures required for life.
What are all cells made of? - Answer: Biomolecules
The smallest fundamental unit of structure and function in life, are fluid-filled spaces bound by a
membrane. When first formed, they include DNA and other macromolecules and are organized to grow,
reproduce, and respond to changes in the external environment. - Answer: Cell
any substance that has mass and takes up space. - Answer: Matter
2 categories of matter: - Answer: biotic (living or having lived) or abiotic (nonliving and never having
been alive).
Abiotic - Answer: describes nonliving materials in the environment, such as sunlight, rain, gases in the
air, rocks, and chemicals in the soil.
Biotic - Answer: living things
,Is water biotic or abiotic? - Answer: abiotic
Are bacteria biotic or abiotic? - Answer: biotic

What are the four main types of biological macromolecules (sometimes referred to as biomolecules or
biomacromolecules)? - Answer: carbohydrates, nucleic acids, lipids, and proteins.
large molecules that are formed by joining smaller organic molecules together - Answer:
macromolecules
Two types of cells: - Answer: prokaryotes and eukaryotes.
The cells of prokaryotes: - Answer: Relatively small and simple; they do not have any clearly defined
compartments inside of them.
, The cells of eukaryotes: - Answer: Include membrane-bound organelles: compartments inside the cell
that contain specific groups of macromolecules and carry out specific cellular functions.
One of these organelles is the nucleus; it encloses the DNA within the cell.
Single-cell life forms, are referred to as: - Answer: Microorganisms.
Tissues: - Answer: Groups of cells that are similar in structure and function
Organs: - Answer: A collection of tissues grouped together based on a common general function. Ex:
heart, lungs, kidneys
Organ system: - Answer: an integrated collection of organs in the body that work together to perform a
vital function
Organisms: - Answer: an individual living entity that survives and reproduces as a unit.
Population: - Answer: All the individuals of the same species that occupy the same area and are likely to
breed with one another.
Community: - Answer: All of the populations interacting with each other within a specified area.
Ecosystem: - Answer: All the living (biotic) things in a particular area together with the abiotic (nonliving)
materials and conditions in that area
Biomes: - Answer: Areas of the Earth with similar characteristics of living and nonliving things
Biosphere: - Answer: All areas on, within, and around the planet Earth that are capable of supporting
life.
