◉ Structural organization levels.
Answer: 1. Chemical
2. Cellular
3. tissues
4. organ
5. organ system
6. organism
◉ Homeostasis.
Answer: The existence and maintenance of a relatively constant
environment within the body
,◉ Negative feedback.
Answer: When any deviation from he set point is made smaller (the
body is correcting the change)
◉ Positive feedback.
Answer: When a response to the original stimulus results in the
deviation form the set point becoming even greater
◉ Covalent bond.
Answer: When atoms share 1 or more electrons
◉ Ionic bond.
Answer: A complete transfer of electrons between two atoms results
in separate positively charged and negatively charged ions.
◉ Polar Covalent bond.
Answer: An unequal sharing of electrons between two atoms results
in a slightly positive charge on one side of the molecule and a slightly
negative charge on the other side of the molecule.
◉ Non-polar Covalent bond.
,Answer: An equal sharing of electrons between two atoms results in
an even charge distribution among the atoms of the molecule
◉ Hydrogen Bond.
Answer: The attraction of oppositely charged ends of one polar
molecule to another polar molecule holds molecules or parts of
molecules together.
