May SAT II Biology E/M

<p>nucleolus or something</p>

<p>nucleolous or something</p>

<p>nucleolus does have a membrane [Nucleolus</a> - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Nucleolus]Nucleolus”>Nucleolus - Wikipedia) i put uhhhhh lol idr really anyone remember the choices?</p>

<p>I think it was nuclear envelope, mitochondrion, chloroplast, something else.</p>

<p>Edit – umm did you read the first line of the article? :P</p>

<p>“The nucleolus (also called nucleole) is a non-membrane bound structure”</p>

<p>it was those 3, endoplasmic reticulum and like something very obvious.</p>

<p>yeah not immediately around it but has the cellular membrane surrounding it? maybe i misunderstood the question lol</p>

<p>lol endo definitely has one right so what other choices would make sense</p>

<p>pretty sure last choice was ribosomes cause thats what i think i put they are on the nuclear membrane so i think i picked that</p>

<p>i dont remember ribosomes being one of the choices.
if it was lol, we probably wouldnt be arguing over the nucleolous</p>

<p>I ended up putting nuclear envelope because I thought that there was no more membrane surrounding the nuclear envelope, but there was (eventually) membranes surrounding the nucleolus. But I was confused by the question…</p>

<p>dont know lol i really wanna see a consolidated list for this test</p>

<p>wat about the one with the pictures of animals?
i put annelids
and the one with the female reproductive system
and i completely guessed on the neuron group of questions
i hope i hit 700</p>

<p>What exactly is the “picture of animals” question?</p>

<p>it was hydra and jelly fish btw</p>

<p>Compiled List (and my own answers that i remember)</p>

<p>Classification</p>

<p>First Group
Mitochondria presence = eukaryotes, but not prokaryotes
Plasma membrane = all
Cell wall = plants, but not animals
Ribosomes = all</p>

<p>Second Group
Chance of having a girl = 50%
Number of generations to get AABB and aabb mix to have 9:3:3:1 phenotype ratio = 2
Number of phenotypes from Aa and aa mix = 2
Number of gametes possible from AaBb = 4
Number of chromosomes of fly cell right before mitosis (haploid number = 4) = 16</p>

<p>Third Group
Mother passing antibodies to fetus = passive immunity
the clumping of anti B antigens with type B blood = agglutination
Release of histamines = allergic reaction
Small pox virus exposure = active immunity</p>

<p>Last Group
Pyruvic acid = glycolysis
Lactic acid = fermentation</p>

<p>Core Section Multiple Choice
To see if rabbit is recessive for white hair=cross with white rabbit and look at offspring
II and IV (Hydra, jellyfish) for only one opening (mouth or something like that)
Two species benefit = mutualism
Islands split, animals different = evolution differs for small populations
Bat wings, fly wings = convergent evolution
Sex-linked recessive (color blind dad, wife husband not)=kid has 0% of getting it
Species is smaller than genus (in overlapping circles)
Colon=water absorption
Changes in alleles = mutation
Egg is fertilized in the oviduct (fallopian tubes)
Starch solution bag = graph looks like decreasing first, then stabilizing
Eardrum = basilar membrane
DDT dangerous = builds up in higher trophic levels
Ostrich=warm blooded animal (unlike trout, lizard, salamander, snake)</p>

<p>Carrot Section
Becomes flexible=cell membranes shrink away from the walls
One on counter sprouts = higher metabolic rate
For experiment with control in light = clear and black plastic bag
Paper bag = carrots become flexible faster than ones in plastic bags</p>

<p>Bacteria Plate section
Most effective = tetracycline (third one)
Control = bacteria on nutrient agar without antibiotics
Penicillin has bacteria forming on white spot=resistant to penicillin strain of bacteria</p>

<p>Earthworm Neuron section
If y is broken, segment 1 will not react when segment three is touched
If neuron n degrades or disappears, segment 1 muscle will not react to touch
Two answers were short three letter combinations tracing the pathways</p>

<p>Zygote Section
Type of organism = angiosperm
Process from Stage 1 to 2 = mitotic division
Which type of human disease = cancer
Presence of auxin = enlargement of cells only (II only)</p>

<p>Food Web Section
Hawk = tertiary consumer
Shrub/grass = most energy</p>

<p>Molecular Bio Section</p>

<p>All are true about mRNA except=double stranded
Gametes are formed by = meiosis
Organelle without membrane = nucleolus
Medelevian cross = Aa with aa
Bean seed mixed = lipids
Vitamins important = act as coenzymes
Actin-myosin thing power by = ATP</p>

<p>Pea Plant Respiration Section
Control = 25 degrees Celsius
Percentage at 7.5 hrs = 125%
Plant dies in 8 hours = 50 degrees Celsius
Why does respiration rate decrease at hour 3 in the 0 degree Celsius one=lower temperature=lower reaction time
Graph of respiration rate of 40 degrees Celsius = a slow increase and then flat line</p>

<p>Activation Energy Section
EA is lowered by enzyme activity
EA is where the bonds between different compounds are made (unstable)</p>

<p>Any comments, remember any more questions?</p>

<p>How difficult is the SAT II biology as compared to the AP biology exam and do they cover the same material? What is the correlation for scores i.e. 5=750-800 4=600-750 etc. etc.</p>

<p>Good job on the list lol
do u remember anymore questions?
i wanna see if i can caculate my score :stuck_out_tongue:
and for urea, it does not provide energy</p>

<p>which molecule contains the most amount of energy?
the answer choices were… starch, cellulose, fat and…i dont remember the other choices</p>

<p>and there was a question about which molecule does not provide energy. i think the answer was urea?</p>

<p>can u explain the sex linked recessive question with the color blind? i forgot what the question is. if i remember what it was, i might remember what i put as the answer.</p>

<p>I put fat and urea</p>
