<p>What about the lab in which the scientist tried to recreate the atmosphere of early earth… what was necessary in the first two experiments? I couldn’t get that one…</p>
<p>For the meesssed up spindle problem. the question said “it interrupts spindle FORMATION”. Prophase is when spindle FORMS. If spindles cant even form during prophase, nothing else can be carried out, not even nondisjunction.</p>
<p>Also for crab species, I put DNA sequences. embryology can be used to determine between phyla andu sub-phyla, such as mammals, chrodates, etc. But it is not specific enough for species differentiation</p>
<p>Also some people seem to be talking about 2 rRNAs in the lab questions. What were the two questions? I dont know if I put two rRNAs as the answers?</p>
<p>For one of the M labs about base differences
1st question was rRNA. forgot the question. something to do with the 0s
3rd question was rRNA. how to distinguish plants, animals, bacteria</p>
<p>Is there any consensus on the pines north south rockys. I put evaporation of water.</p>
<p>@zsATnot ACT, the two rRNA quesitons on the lab.
For the plants animals bacteria, was rRNA with 0 6 18 base differences?
Can anybody remember the quesiton to the first rRNA answer choice?</p>
<p>I am still researching about the pine tree. But I still think evaporation. In the western USA, cold air from canada and warm air from mexico and gulf come together. Warm air from the south has a higher tendency to pick up water molecules in evaporation. Pines, which are large trees, seem to require a crap ton of water (IDK. just assumption about size). So I reasoned out with northern slope with less evaporation but I am still reading around.</p>
<p>for epithelial cells in guts, it is tight junction not cilia. Cilia are hair, what we have instead is villi but that is not an answer choice. Tight junciton holds liquid together</p>
<p>For tomato sickness, it is virus. They want the smallest answer choice and virus is smallest.</p>
<p>Fat inndeed has higher energy efficiency compared to any other molecule.</p>
<p>For the base difference lab, I remember using the answer choice with 0 6 18 base differences as the answwer to the question regarding differences between animal, plant, and bacteria</p>

<p>Is this spindle fiber question part of the Molecular Specific?</p>
<p>I am not sure. but I thought spindle fiber was on the general test?
Someone correct me though…</p>
<p>I recall a question from the general part: What is NOT part of prophase I. I put cytokensis? Can somebody confirm?</p>
<p>spindle fiber was M specific.
I was torn between prophase and anaphase.
I put prophase, others are saying anaphase.</p>
<p>yes that is correct I seem to remember that.</p>
<p>Pretty sure it was on m.
Did you get gene flow for 2 questions in the beginning of the general</p>
<p>omg on the E test, the frog, lizard, alligator, something question was literally from the PR book! i took M, but i looked through E and it was the first question. And what exactly was the epithelial question? I put tight junctions</p>
<p>@Asdfghjkl825</p>
<p>I used genetic drift for one and gene flow for another one.
Gene flow is change in allele frequencies while genetifc drift is change in variation of genotypes because of an event(?). I may be wrong.</p>
<p>Damn I should’ve studied from pr…I skipped it but what was the answer?</p>
<p>I put natural selection for new climactic conditions
I put mutation for new genes
I put genetic drift for another one
I don’t think I put gene flow for any</p>
<p>What about the question about law of independent assortment? When one gene affects the other, was the answer E, they are linked?</p>
<p>@asdfghjk</p>
<p>I remember writing mutation and genetic drift. One question was a new allele suddenly appearing in an ISOLATED. sicne this population is isolated, it cannot have gene flow (alleles comingin and out of population). It is also not genetic drift (which is chanage in frequencies of alleles over time) since new alleles cannot form through random mating. INstead it is mutation that creates new alleles.</p>
<p>Second question was about alllele disappearing over time in a small population through random mating. This is the exact definition of genetic drift, which is the chagning frequencies of alleles in a populatin slowly over time in a population</p>
<p>@santaman.
Yes linked genes</p>
<p>linked was an answer to one of them. something about not obeying independent assortment.</p>
<p>What about the question about plant fertilizer? The answer choices were carbs, proteins, nucleic acids, etc… anybody?</p>
<p>So how difficult was this test compared to previous ones?</p>
<p>There was another question: A gene sequence is shown and a complementary DNA strand is backwards… was it an inversion?</p>
<p>santaman1, if you go back to earlier posts you might find some answers.
you answered your own question by recognizing its being backwards. It was inversion.
For fertilizer I put inorganic molecules
I thought this test was slightly easier. The labs were easier. It was definitely very E focused.</p>
