<p>Hey, guys
I'm getting confused with those many posts on the Biology Thread.
Let's do a compilation of all the questions that showed up on the test. I took E not M so I'll need your help guys. :)</p>
<p>The diagram that showed a terminal portion of the nervous system of a segmented earthworm:
What effect would the destruction of neuron n have on the earthworm?
The muscular movements at only segment I would be stopped.
If the worm is touched at segment III, the muscles in the segment contract. Which neurons are responsible of this stimulus-response reaction?
w, u, v
If neuron y in ganglion IV were destroyed, which of the following would be the result?
Segment I would not respond to a stimulus at the skin of segment III.</p>
<p>If the earthworm is touched at segment III, and the muscles in two respond, which neurons are responsible?</p>
<p>w, t, q.</p>
<p>process that produces pyruvic acid: Glycolysis
process that can produce lactic acid: Fermentation</p>
<p>A scientist wants to check if a black guinea is heterozygous for the fur color trait?
mating the black guinea with a white recessive one and observing the offspring</p>
<p>the antibiotics experiment:
the best treatment to eliminate infections: penicillin
which would be a control in a petri dish: no antibiotics
penicillin had colonies in the white area: the new colonies have a penicillin resistance </p>
<p>the carrots experiment:
carrots in paper bags become more flexible than carrots in plastic bags</p>
<p>the best treatment to see the effect of light:</p>
<p>black plastic bag and clear plastic bag</p>
<p>why carrots become flexible:</p>
<p>water evaporates and cell membrane shrinks.</p>
<p>the ones that sprouted: higher metabolic rate</p>
<p>bacteria in roots: nitrogen cycle</p>
<p>the atmosphere didn't contain: Oxygen.</p>
<p>order of level of organization: population community ecosystem biosphere</p>
<p>effect of DDT: resistant.. survived.. reproduced.</p>
<p>larger number of people if we eat: fruits and vegetables.</p>
<p>the tertiary consumers: hawks</p>
<p>greatest amount of energy: Grasses</p>
<p>the cat listening to the can being opened: conditioning.</p>
<p>muscles need: ATP</p>
<p>color-blindness ratio of sons: .5</p>
<p>little evolutionary change: enviromental niche that remained somehow stable</p>
<p>exposure to heat: blood circulation on the skin surface.</p>
<p>rain forest are all of the following except: temperature fluctuations.</p>
<p>the one that had different species out of one species: adaptive radiation</p>
<p>the ocean is least productive in the: abyssal zone</p>
<p>adaptation in the abyssal zone needs: low temperature and high pressure adaptation.</p>
<p>the one that asked about the birch, oak and beech:</p>
<p>respiratory losses more than photosynthetic gains.</p>
<p>the one asking about three leaves will remain the same 1000 whatever..</p>
<p>succession: late succession species have higher rates of photosynthesis</p>
<p>250 joules</p>
<p>getting reliable data from all of the following except: unchanged temperature.</p>
<p>the one having flies</p>
<p>400 flies.</p>
<p>x is a better competitor.</p>
<p>if we started with 200 instead of 100: I can't remember the answer.. i think i said something about remaining in equilibrium (not sure though)</p>
<p>the one that asked about most related species: something californicus and something floridanus.</p>
<p>one asking about starch: starch wouldn't go anywhere.</p>
<p>the role of colon: absorption of water.</p>
<p>oxidative-reduction: electrons.</p>
<p>the cochlea vibrates faster with lower pitch.</p>
<p>the one with two circles: species - genus.</p>
<p>which of the following is always required in successful reproduction in multicellular organisms: haploid.</p>
<p>the female reproductive system: oviduct</p>
<p>energy is most in: lipids.</p>
<p>the one about new alleles: mutation.</p>
