Bio 110 PSU Exam 1 Questions With
Correct Answers
anabolism - CORRECT ANSWER✔✔-uses energy to consturct
| | | | | | |
components of cells | |
catabolism - CORRECT ANSWER✔✔-breaks down organic matter, for
| | | | | | | |
example to harvest energy
| | |
hydrogen bonds - CORRECT ANSWER✔✔-attraction between partial
| | | | | | |
charges of water| |
- to other water molecules
| | | |
-to polar or charged non water molecules
| | | | | |
- partial charges act as magnets
| | | | |
individual bonds are weak but over millions of molecules become very
| | | | | | | | | | |
strong
surface tension - CORRECT ANSWER✔✔-water molecules at the surface
| | | | | | | | |
are pulled down by hydrogen bonding with water molecules beneath
| | | | | | | | | |
them
, cohesion - CORRECT ANSWER✔✔-attraction of water molecules to
| | | | | | | |
other water molecules
| |
--hydrogen bonds determine cohesiveness | | |
photosynthesis - CORRECT ANSWER✔✔-where does it take place? | | | | | | |
-leaves
where does water come from?
| | | |
-roots from the ground
| | |
how do water molecules move from soil to the leaves?
| | | | | | | | |
-transpiration (water moves up narrow tubes with cohesion and
| | | | | | | | |
adhesion)
why do dogs and people sweat - CORRECT ANSWER✔✔-regulates body
| | | | | | | | | |
temperature, specific heat | |
water has high heat of vaporization
| | | | | |
--- evaporative cooling, temperature buffer
| | | |
when water vaporizes what bonds are broken? - CORRECT ANSWER✔✔-
| | | | | | | | |
hydrogen bonds between water molecules
| | | |
how can organisms live on or under the ice? - CORRECT ANSWER✔✔-
| | | | | | | | | | |
hydrogen bonds expand and water becomes less dense allowing it to
| | | | | | | | | | |
float
