Can you tell me how many minutes I should spend on each question for MC?
my teacher keeps insisting that we can use ti-30 calcs even when the website says you can’t. So when everybody brings that calc, they can’t use it right because it’s a breach in the rules right ?
@AsianDoctor I don’t think you can use the ti-30. For my exam, they’ll provide the calculator for us and it’s not scientific or anything fancy like that.
what are important topics to review for nervous system?
@AnniiT that’s what i thought. but if my school says something like, “oh, go ahead, you can use it, we are amongst friends” that’ll have to be reported right ?
since the bio test is different from previous years, will the old frq’s be similar though ?
I’ve been consistently scoring 60-65% on the multiple choice section. Is that high enough to get a 4 assuming I do about the same or better on FRQs?
@trfox7 central nervous system, peripheral nervous system, and reflex arcs
The practice 2013 and 2014 tests only have 53 mc the the grid ins in 90 mins. I thought the actual test was 63 mc then the grid ins in 90 mins. Did they change it or something?
Do you think they’d ask about operons?
@mwm247 i think so
I just got a 47/69 on one of the practice tests. What is that close to a 3,4 or 5?
I think that’s near a 3-4 range @RoadtotheIvies98 Did you use the 2012 exam?
do we need to really know those few hormones they ask us to look at
@redpower yeah sorry my spelling on this thread was atrocious if you look at older posts you’ll also see that I spelled “Weinberg” wrong . I was really tired last night when I was typing on this thread .
Do we need to know all the systems for the test?
my teacher only taught us the immune system and a bit of the nervous system.
should I know more?
@opg321 We spent did endocrine, nervous, immune, circulatory, respiratory and urinary in class. My teacher told us that immune and nervous are the most commonly tested on, however. I’ve seen some MC about closed vs. open circulatory systems, so you might want to check those up.
Does anyone know if Hardy-Weinberg calculations are on this year’s exam? My teacher told me they aren’t.
Okay I made this account just because I saw this question, YOU NEED TO KNOW HW EQUILIBRIUM
What do we need to know about embryonic development aside from HOX genes and its evolutionary indications?
I understand that Barr body formation, or methylation of an x chromosome in females, is random for every somatic cell, which results in the difference in coloration that creates a tortoiseshell cat. However, genomic imprinting, which is also caused by methylation/silencing of a parental chromosome in gametes, is irreversible and the same parental chromosome is silenced throughout all somatic cells.
If a chromosome is genomically imprinted, will it also be imprinted when that individual produces their own gametes? Does genomic imprinting only apply to particular genes/chromosomes, or does it mean that an individual will have the same parental phenotype? Is it a reversible process?
