<p>@nwgolfer321: I thought that question was really vague… couldn’t cornea and lens be both right answers??
“The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.”</p>
<p>I chose lens in the end…</p>
<p>^^agreed.<br>
^idk i put the cornea. but they really shouldnt put questions with more than one possible answer</p>
<p>dasheeky, this is exactly what i thought when i took the test, but in one of PR’s practice tests, this is apparently wrong.</p>
<p>no im pretty sure the question asked the organism that causes malaria is a …
otherwise the answer would’ve been too obvious
it can’t possibly be a herbivoire or anything else</p>
<p>@nritya- I think it said causes, but either way, the plasmodium is a parasitic protist.</p>

iris controls how much light enters the eye and lens allows the shape to appear in the retina</p>
<p>what was the PR explanation?</p>
<p>yes. so i actually put…
Cornea- focuses light
Iris- controlls how much light gets in
optic nerve- part of nervous system</p>
<p>the cornea is outside
the lens was choice D and is actually responsible for focusing</p>
<p>other answers we haven’t talked about:
cnidaria - radial symmetry
bacteria and mitochondria having the same lipid layer (double membrane) hence proves the endosymbiotic theory
cohesion- water property that lets water to go up a tree trunk
chromosome mutation: anything but deletion, inversion, nondisjunction, and translocation
… anything else?</p>
<p>okay i think you read wiki, which is why you think its the cornea. if you read past the first sentence in the wiki entry for lens:</p>
<p>“The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. The lens, by changing shape, functions to change the focal distance of the eye so that it can focus on objects at various distances, thus allowing a sharp real image of the object of interest to be formed on the retina.”</p>
<p>although the cornea also focuses light, it is the LENS that focuses that light on the retina.</p>
<p>cnidaria - radial symmetry
cohesion
that’s all i remember out of what u said biologygeniius</p>
<p>other answers continued:</p>
<p>pedigree of red-green color blindness:
sex-linked recessive (for sure) and the two other questions were easy</p>
<p>i thought bacteria had peptidoglycan rather than a lipid bilayer?</p>
<p>that’s what I thought too
I said that both had similar RNA but that was just because none of the others seemed correct</p>
<p>other answers continued:</p>
<p>-a question about independent assortment- 9:3:3:1 (with actual data #s)
-genetic variability
-glycolysis (i think this was the first question in the multiple choice Q)
-Darwin’s 5 things that was not true: “acquired trait passed on to next generation” false
that was Lamark’s idea</p>
<p>Same dasheeky</p>
<p>I put similar RNA.
“Mitochondrial ribosomes and transfer RNA molecules are similar to those of bacteria, as are components of their membrane.” That kind of goes two ways, I don’t know.

<p>I didn’t have an independent assortment question at all…was this on E?
Oh, and what did you guys put for lysosomes? I put hydrolysis.</p>
<p>@nytria
the question about the bacteria and mitochondria was a made up question. i think</p>
<p>@dasheeky and nwgolfer321
i also said about them having the same RNA or something but that does not prove endosymbiotic theory of which the question is looking for…</p>
