UMD BSCI170 Exam 1 with all Correct & 100% Verified
Answers| Latest Update| Already Graded A+
emergent properties ✔Correct Answer--interaction of parts to create complexity; the more parts,
the more complex
properties of life ✔Correct Answer--to consume energy, to reproduce, to create order, to self
regulate, to respond to environment, to evolve
big ideas of bio ✔Correct Answer--structure function relationship, energy transformation,
emergent properties, regulatory mechanisms, evolution
cell theory ✔Correct Answer--all cells come from one another
evolution ✔Correct Answer--everything shares a common ancestry that evolves with time
endomembrane system ✔Correct Answer--- splits cell into different compartments which allows
cells to be doing multiple things at once
- allowed eukarya to evolve and become more complex
endosymbiont theory ✔Correct Answer--eukaryotes consumed a prokaryote, a membrane was
created to be able to protect itself from the prokaryote and to be able to use the energy that it
creates (mitochondria)
atomic weight ✔Correct Answer--mass of protons and neutrons
covalent bonds ✔Correct Answer--shared electrons (only similar elements with similar electro-
negativities can do this)
ionic bonds ✔Correct Answer--give and take electrons (elements with differing en)
hydrogen bonds ✔Correct Answer--bonds with hydrogen that occur do to polarity
properties of water ✔Correct Answer--adhesion, cohesion, surface tension, heat capacity,
evaporative cooling
cohesion ✔Correct Answer--water sticks to itself; many molecules are linked by hydrogen bonds
adhesion ✔Correct Answer--water sticks to other polar molecules; helps water climb up cell walls
surface tension ✔Correct Answer--measure of how difficult it is to stretch or break the surface
heat capacity ✔Correct Answer--water is a very effective heat bank; release heat with only a slight
change in temperature
evaporative cooling ✔Correct Answer--takes lots of energy to evaporate water; sweat & forcing
water to evaporate
