Metabolism - correct answer ✔✔All of the chemical reactions that occur within an organism
Homeostasis - correct answer ✔✔A tendency to maintain a balanced or constant internal state; the
regulation of any aspect of body chemistry, such as blood glucose, around a particular level
Ecological Organization - correct answer ✔✔organism, population, community, ecosystem, biosphere
Hypothesis - correct answer ✔✔A testable prediction, often implied by a theory
Theory - correct answer ✔✔well-tested explanation that unifies a broad range of observations
model - correct answer ✔✔A representation of an object or event
Scientific Method - correct answer ✔✔A series of steps followed to solve problems including collecting
data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
Stimuli - correct answer ✔✔Changes in the environment
asexual reproduction - correct answer ✔✔offspring are typically identical to a single parents, except in
size.
sexual reproduction - correct answer ✔✔involves the fusion of an egg and sperm
Adaptations are - correct answer ✔✔traits that increase an organism's reproductive success or survival
biological organization is - correct answer ✔✔hierarchical
tissues - correct answer ✔✔Groups of cells with a common structure and function. ex: muscle, and
connnective tissues
organs - correct answer ✔✔In most mulicellular organisms tissues organize to form functional structures
called
, organ system - correct answer ✔✔group of organs that work together to perform a specific function
Organism - correct answer ✔✔A living thing. (made up by an organ system.)
Population - correct answer ✔✔the basic unit of ecological organization is the
Communities - correct answer ✔✔various populations
Ecosystem - correct answer ✔✔A biological community of interacting organisms and their physical
environment.
Biosphere - correct answer ✔✔all of earth's ecosystems
DNA - correct answer ✔✔Makes up genes, is the hereditary material
DNA is transmitted from - correct answer ✔✔one generation to the next
DNA codes for - correct answer ✔✔proteins. Which are important in determining the structure and
functions of the cells.
Hormones - correct answer ✔✔Chemical messengers that transmit messages from one part of an
organism to another.
cell signaling - correct answer ✔✔The process of cell-to-cell communication mediated by signaling
molecules and membrane receptors
Neurotransmitters - correct answer ✔✔electrical signals that transmit information; most animals have
nervous systems that transmit electrical impluses and release..
Photosynthesis - correct answer ✔✔Conversion of light energy from the sun into chemical energy.
cellular respiration - correct answer ✔✔a biochemical process in which they capture the energy stored
in nutrients by producers.
producers/autotrophs - correct answer ✔✔Organisms that make their own food
primary producers - correct answer ✔✔eat producers, which typically are secondary consumers that eat
primary consumers.
Decomposer - correct answer ✔✔obtains energy from by breaking down waste and dead organisms.
composters/decomposers - correct answer ✔✔heterotrophs.
Speices - correct answer ✔✔A group of organisms that are physically similar and can mate with each
other and reproduce.
gene pool - correct answer ✔✔Combined genetic information of all the members of a particular
population
