regulation, energy processing, growth and development, response to environment, reproduction
What is the characteristic "order"? - ✔✔ANS Life is structured into a developmental hierarchy
The ____ itself is highly ordered as it contains organelles, a dedicated cytoplasmic space, conducts
metabolic processes, and undergoes microscale adaptions. - ✔✔ANS cell
What is evolutionary adaptation? - ✔✔ANS Smaller, genetic changes that allow for better survival of an
organism.
Evolutionary adaptation should not be confused with...? - ✔✔ANS Species evolution
What is an example of evolutionary adaptation? - ✔✔ANS Color camouflage
What is another name for evolutionary adaptation? - ✔✔ANS Generational evolution
What is regulation? - ✔✔ANS The ability for a living organism to maintain optimal living conditions
Living organisms are sensitive to...? - ✔✔ANS Temperature, environmental stress, pH requirements
What is homeostasis? - ✔✔ANS Maintaining set points of living conditions
What is an example of regulation? - ✔✔ANS Shivering to regulate body heat
,What is energy processing? - ✔✔ANS How an organism utilizes biochemical reactions to produce energy
What is the sum of an organism's biochemical reactions referred to? - ✔✔ANS Metabolism
What is ATP? - ✔✔ANS Biological fuel or energy
What type of metabolism do many prokaryotes use? - ✔✔ANS Anaerobic
What is photosynthesis? - ✔✔ANS A plant using light to trap energy
Many prokaryotes metabolize ____? - ✔✔ANS Organic substances
What type of metabolism do animals use? - ✔✔ANS Aerobic
Animals ____ and use ____ as part of aerobic respiration to produce ATP - ✔✔ANS ingest food,
biomacromolecules
What is growth and development? - ✔✔ANS Change over a life cycle. A living thing grows, matures,
ages, and dies.
Living things respond to their environment through...? - ✔✔ANS adaption
What is adaption? - ✔✔ANS A change or process that allows an organism to become better suited for
their environment
adaptions can be ____ or ____ - ✔✔ANS Physical, behavioral
What is a stimulus? - ✔✔ANS anything that causes an organism to respond
, What is an example of a physical adaption? - ✔✔ANS A crab's hard shell
What is an example of a behavioral adaption? - ✔✔ANS A squirrel hibernating
What is reproduction? - ✔✔ANS A living thing's way of producing new and thriving generations to
replace previous ones
Reproduction can occur ____ or ____ - ✔✔ANS Sexually or asexually
What does sexual reproduction involve? - ✔✔ANS Fusion of two gametes that unite and grow into new
offspring
What does asexual reproduction produce? - ✔✔ANS New offspring from a single organism
What are examples of asexual reproduction? - ✔✔ANS Spore formation, binary fission, vegetative
reproduction, budding, fragmentation
What organisms use spore formation? - ✔✔ANS Protozoa, bacteria, plans, fungi
What organisms use binary fission? - ✔✔ANS Prokaryotes and some eukaryotic protozoa like amoeba
What organisms use budding? - ✔✔ANS Fungi, bacteria, some plants, fewer animals
What organisms use fragmentation? - ✔✔ANS Segmented worms and echinoderms like starfish
How can the levels of biological organism be described? - ✔✔ANS Successive, broadest to smallest
What are the levels of biological organization? - ✔✔ANS biosphere, ecosystems, communities,
populations, organisms, organ systems, organs, tissues, cells, molecules and atoms
