<p>I put nucleus. Yes fission was the repulsion of the protons (two likely charged particles always repel each other.) Still don't remember the ion question, but I'm thinking its because that was the last passage I did and I rushed through it.</p>
<p>I don't remember the context for the ion question, but it was basically a definition. Not hard, but also not reasoning</p>
<p>don't chloroplasts give plants and algae their green color and therefore would be susceptible to stain to purple or pink?</p>
<p>Did anyone guess on the last three/four questions in the science section? That was all chemistry stuff I had completely forgotton.</p>
<p>wait wait. they have a curve on the ACT? WHAT!!! i didn't know this.</p>
<p>anyways, yea the science section is rediculously impossible. Not as bad as reading, but they're like "if 51 21 Y = Neutron N 1 + x, i'm like ***! what does that mean"</p>
<p>nah the last science passage was insanely easy, you basically subtracted 1s and 2s for two or three of the questions</p>
<p>what was that one where it was like x and y are the same or soemthing...... 117/42?</p>
<p>I just found it, bacteria does not have a nucleus, because they are prokaryotes.</p>
<p>Jeremybeach, they don't curve the ACT per se, but they do have a different "set curve" each test.</p>
<p>ok, they cannot expect students to know what a prokaryote is.</p>
<p>I am not stupid, but I was not prepared for a subject test in Biology. I was prepared for science Reasoning</p>
<p>The answer is cell membrane, because bacteria lack membrane-bound cell compartments such as, mitochondria, chloroplasts, and nuclei.</p>
<p>Yeah, you're right, there is no way that I would've been able to narrow it down, if I had not had some biology in the past.</p>
<p>Alright I was a little hasty...but the ion one I did my best guess from what I knew and the staining I just thought about it. You know that chloroplasts arn't in bacteria and it probably wouldn't be the nucleus because for the cell to stain it'd have to be the whole cell. And you know the cell membrane encompasses the whole cell, so that was my guess.</p>
<p>The answer is nuclues, naw i don't know.</p>
<p>the science was hella hard and I will be writing to ACT 2day</p>
<p>i hope most answers were D or J.</p>
<p>hahaha yeah i know it seems like most of the answers were H or J (or D i mean)</p>
<p>im only saying that because i guessed a LOT, and i guessed the last letters, which are D OR J... (act likes D/J answer choices..)</p>
<p>I put cell membrane and im pretty sure its right--</p>
<p>There are broadly speaking two different arrangements of the cell wall in bacteria, called Gram positive and Gram negative. The names originate from the reaction of cells to the Gram stain, a test long employed for the laboratory classification of bacterial species.</p>
<p>Gram positive bacteria possess a thick cell wall containing many layers of peptidoglycan and teichoic acids. In contrast, Gram negative bacteria have a relatively thin cell wall consisting of a a few layers of peptidoglycan surrounded by an outer lipid membrane containing lipopolysaccharides and lipoproteins. Most bacteria have the Gram negative cell wall; only organisms from the Phyla Firmicutes and Actinobacteria (previously know as the or low G+C and high G+C Gram positive bacteria, respectively).</p>
<p>--i love wikipedia</p>
<p>How about the question concerning why the experiment didn't go deeper than 20km (or whatever the length unit was), i realized i made a careless mistake and changed it right as time was called and put D, but I really didn't have time to think it through.</p>
<p>I thought D was "because the roots of sand grass don't extend pass 20" or something like that</p>
<p>Can anyone confirm this?</p>
<p>I put cell member, I think. But yeah, that science was pretty rough, especially compared to my last test, and all practice tests. I saw a few that I couldn't get that I looked at for awhile. There is no need for us to worry now though, as regardless to what we think about, we can't change it now. Best of luck to everyone though.</p>
<p>I was thinking the grass roots wouldn't go any lower??</p>
