Questions and verified study solutions
What is science? - ANSW-Science is to Know; It is a body of information about the material world which
has been collected by vigorous, critical, and collective methods which is subjected to continuous testing
and retesting backed by a supported hypothesis. Science cannot answer ethical or moral questions.
Science is constantly changing; as technology progresses, science also progresses. Scientific theories get
tossed aside as science evolves.
What is the difference between a hypothesis, a theory, and a law? - ANSW-Theory is a hypothesis that
has lots of evidence to prove it.
Hypothesis is statement or generalization without evidence.
Laws: Ultimate laws that evolved from a theory. I.e. E=mc2.
Explain what a controlled experiment is? - ANSW-A control group is involved with two
groups:experimental and controlled. Experimental group is one directly involved with the experiment.
Control group is used as to compare the effects of an experiment on the experimental group.
What is Biology? - ANSW-Study of Life
What is evolution? - ANSW-process of change over time; transformed all life on earth to what we know
of it today
What are the seven attributes of living things? - ANSW-Order
Evolutionary adaptation
Response to the evironment
Growth and development
Regulation
Reproduction
Energy processing
What are the levels of biological organization? - ANSW-Biosphere
ecosystems
communities
populations
organism
organ system
organs
tissues
cells
organelles
molecules.
, What is invetrofertilization? - ANSW-• Invetrofertilization was used to help humans have children. Race
horses and cattle were used for implantation first and so they thought they could use it on humans.
What is the difference between negative and positive feedback? - ANSW-Negative feedback: continuous
accumulation of end product returns less of the end product
Positive feedback: continuous accumulation of end product returns more of the end product
list the eight categories of organism classification? - ANSW-
Domains>Kingdoms>phylum>class>order>family>Genus>Species
"Dear King Phillip Came Over For Ginger Snaps"
How many domains are there? List them. - ANSW-Three Domains: Eukarya, bacteria, and archaea
Which two domains are prokaryotic? Eukaryotic? - ANSW-Bacteria & Archae
Eukarya
list the four kingdoms in Eukarya. - ANSW-Fungi, animals, protists, plants
Which of the three Domains is/are unicellular? Multicellular? - ANSW-Unicellular: Bacteria and Archae
Multicellular: Eukarya
Which of kingdoms in Eukarya is/are unicellular? Multicellular? - ANSW-Unicellular: protists
Multicellular: animals, plants, fungi
Which of the kingdoms in Eukarya are autotrophic, heterotrophic, phototrophic or chemotrophic? -
ANSW-Protista: hetero/auto
Fungi: hetero
Plants: photo/auto
Animals: hetero
Which domain consists of chemotrophs? - ANSW-Bacteria
how is photosynthesis differet than cellular respiration? - ANSW-Opposite reactions
Photosynthesis: CO2 + H20------glucose + O2
Cellular respiration:Glucose + O2------CO2 + H20-----ATP
What is spontaneous regeneration? - ANSW-People used to believe organisms formed from the
environment and its surrounding properties.
What are the primary functions of positive/negative feedback? - ANSW-To obtain homeostasis; maintain
same conditions
What is an ion? - ANSW-An atom with a charge
list these bonds in order from strongest to weakest: hydrogen bonds, covalent bonds, van-der wal forces,
ionic bonds - ANSW-1. Covalent bonds
2. Ionic bonds
3. Hydrogen bonds
4. Van-der wall forces
What is electronegativity? - ANSW-An atom's strength of attraction to electrons. Some are stronger than
others.Electronegativity increases as you go up and right of the periodic table. Fluorine is the strongest.
Which of these pairs are more electronegative:
