GRADED A+
Biology Correct answer-the study of living organisms
homeostasis Correct answer-the tendency of an organism or cell to regulate its internal conditions
DNA Correct answer-carrier of genetic information in all living organisms
population Correct answer-a group of the same type of organisms living in the same area
species Correct answer-members within a group that can interbreed
evolution Correct answer-descent with modification; genetic change in population over time
who formulated the scientific theory of evolution by natural selection? Correct answer-Charles
Darwin
photosynthesis Correct answer-the process in which an organism is able to obtain energy from
sunlight
gene Correct answer-a segment of DNA
mutation Correct answer-the changing of a gene, resulting in a variant form that may or may not
be passed down to offspring
what is the hierarchy of life? Correct answer-atoms<molecules<cells<tissues<organs<organ
systems<multicellular systems<species<populations<community<ecosystems<biosphere
what are the characteristics that ALL organisms share? Correct answer--reproduce
-respond to stimuli
-grow
-acquire energy and utilize it/materials/air, water, soil, other organisms
-maintain an organized complexity/homeostasis
-evolve *change
characteristics of a prokaryotic cell Correct answer--"before nucleus" (no nucleus)
-smaller
-unicellular
-lack membrane-bound organelles (simple)
-bacteria & archaea
characteristics of a eukaryotic cell Correct answer--"true nucleus" (nucleus)
-larger
-multicellular
-membrane-bound organelles (complex)
-plants, animals, fungi, & protests
, name two ways in which organisms obtain energy Correct answer-photosynthesis and
consumption
what is the chemical formula for photosynthesis Correct answer-
give an example of homeostasis Correct answer--sweating/shivering (body temp)
-ph (lactic acid in muscles after running)
what are the few similarities between humans and chimpanzees Correct answer--anatomy
-physiology
-DNA (5% different)
-embryology
-behavior
Did humans evolve from chimps and monkeys? Correct answer-we did not evolve from chimps or
monkeys, we share a common ancestor
in order for a species to evolve, which three natural processes need to occur? Correct answer--
mutations
-natural selection
-inheritable
what type of mutation would not have an effect on an organism Correct answer-a neutral mutation
why would a neutral mutation not have an effect on an organism Correct answer-it is located on a
segment of DNA that doesn't code for a protein
what is often described as "survival of the fittest" Correct answer-natural selection
what are structures , physiological processes, or behaviors that aid in survival and reproduction
Correct answer-adaptations
what are ways that humans can often accelerate the rate of environmental change? Correct
answer--burning fossil fuels
-global warming
-habitat change
what man is responsible for organisms' binomial nomenclature Correct answer-carolus linneaus
binomial nomenclature: humans Correct answer-Homo sapiens (italicized or underlined)
biologists test using ________________ experiments that must be repeatable, even by others
Correct answer-controlled
there are three natural processes that underline evolution: mutation, natural selection, and
inheritance of traits by offspring Correct answer-true
DNA codes for proteins Correct answer-false
what codes for protein Correct answer-genes
