@EveningSwan Yes
Any predictions for what the free responses may be on? Like possible labs we should focus on?
@ludkis id be up for it
@ludkis go for it
All right everyone here feel free to join this kik chat. Go to search and put “#apbiocc”
We can review for tomorrow and answer anyones questions
Quick Questions:
- Does Helicase unwind the DNA in RNA Transcription? Or does RNA Polymerase 2 do that?
- Before Meiosis, does a cell have 92 total chromosomes (4 copies of each)?
- What do I specifically have to know about Cell Communication? I know about the Nervous System and Endrocrine System. I also vaguely know about the proteins and carbohydrates on the Plasma Membrane.
- Do I have to know specific hormones for the Endocrine System? I only know how it functions and what body parts compose it.
- Do I have to know about any significant phylums such as Portifera, Mollusca, or Anthropoda?
MODERATOR’s NOTE:
The link can’t be posted here.
if i got a 60% on the mc what does that give me ? a 3 ?
Cool
will do @ludkis
chat is up and running. feel free to join it.
@Ludkis count me in how do i join
Quick Questions:
- Does Helicase unwind the DNA in RNA Transcription? Or does RNA Polymerase 2 do that?
Helicase/Topoisomerase only unwinds the DNA regardless of replication or transcription. The Polymerases only fixate new nucleotides in complimentary to the template strand.
2) Before Meiosis, does a cell have 92 total chromosomes (4 copies of each)?
A cell only have 92 total chromosomes when it is about to undergo meiotic division so right before meiosis the total number of chromosomes is duplicated so that 46 pairs of chromosomes get splits into 23 pairs after meiosis I and then 23 individual homologues after meiosis 2 for the gametes.
- What do I specifically have to know about Cell Communication? I know about the Nervous System and Endrocrine System. I also vaguely know about the proteins and carbohydrates on the Plasma Membrane.
Know the different methods of cell signaling (tyrosine-kinase, G-protein, neural signaling, endocrine signaling, immune responses, ect. ) but not stuff like circulatory or muscles (just know neurons control muscles aswell).
- Do I have to know specific hormones for the Endocrine System? I only know how it functions and what body parts compose it.
Not really. Just know ADH (antidiuretic hormone which increases absorption of water and increases salinity of urine) and oxytocin (love hormone essentially)
- Do I have to know about any significant phylums such as Portifera, Mollusca, or Anthropoda?
Nope. Theses are most likely beyond the scope of the AP because the AP will give you any info for a question that involves specifics but you’re responsible for knowing Animals, plants, bacteria and maybe fungus (not too in-depth though)
@elyvine Thank you SO much! You answered those questions so perfectly. Now I know that I have to do study Cell Communication, because I have no idea what half those terms even mean. 
Does your teacher do “labs” in your classes? Because my teacher only did 4 labs and i worry if ap exam test on labs
Any tips on last minute prep for the frq’s?
@soosoo948 Do you like have no idea what to say, or are you just struggling with getting points? To get points, make sure you state both the obvious and nonobvious things. And pay attention to the boldface words
@TopOne The AP exam is not on labs. Just relax, and understand the point each lab was trying to prove
Two questions:
1)When calculating chi square, is it the matter of if x is > or < the critical value, or if x^2 is > or < it?
- Can someone quickly explain how to make a graph…? Like, which points should I put on the X axis, etc?
Is the molecular basis of inheritance stuff like RNA replication and transcription, translation stressed on the test? Im running out of time to study so I was planning to just watch some videos on the topic.
- if x^2 is greater than your critical value, you reject the null hypothesis.
- x axis is your independent variable (like time) and y axis is dependent variable (temperature)
