<p>It’s simple - you don’t.</p>

482

<p>LoL ^ sounds good to me.</p>

<p>you guys want to start throwing out some MC questions? I’ll go first:</p>

<p>The function of which of the following structures is NOT directly related to diffusion or active transport across its membranes?</p>

<p>A Aorta
B Small Intestine
C Nephron Tube
D Capillary
E Alveolus</p>

483

<p>Do more for plants!</p>

484

<p>i still dont get how to know if in a pedigree, if traits are autosomal dominant/recessive or sex-linked dominant/recessive</p>

485

<p>Good luck tomorrow every body! Let’s hope for the best!</p>

486

<p>@lilliann omg i love those methods you came up with! xD for pinocytosis though, I think of pina coladas xD (PINo= PINa) </p>

<p>Lame, but it works every time :D</p>

487

<p>^^A? The aorta branches into arteries and then eventually capillaries that diffusion occurs across.</p>

<p>Fats are emulsified by which of the following substances synthesized by the liver? </p>

<p>A) Cholesterol
B) HCl
C) Lipase
D) Bile salts
E) Glycerol</p>

490

<p>Bileee (which is stored in the gallbladder)</p>

491

<p>@LesleyCordero :
Bile.
Is bile stored in the gall bladder?
EDIT: Haha wow penguin, nevermind then.</p>

492

<p>Btw, post any acronyms or weird things you use to remember stuff :3</p>

<p>Lol I already said my pinocytosis one… </p>

<p>IPMAT for the sequence of mitosis/meiosis phases (I’m sure you know that one though. =p )</p>

<p>EDIT: Yuppp; bile. :p</p>

493

<p>D- bile saltes (produced in liver, stored in gall bladder)</p>

494

<p>I knew that one! I feel a little better about the exam haha.</p>

495

<p>plant tissues:
ground tissues

  • parenchyma cells - thin walls (pare down = trim down), P is for photosynthesis
  • collenchyma cells - thick and flexible (picture a chunky gymnast named colleen)
  • sclerenchyma - even thicker (picture a CHUNKIER gymnast named clere)</p>

<p>hahaha are those even important</p>

496

<p>The carbon that makes up organic molecules in plants is derived directly from…</p>

<p>A) Combustion of fuels
B) Carbon fixed in photosynthesis
C) CO2 produced in respiration
D) Carbon in the lithosphere
E) Coal mines</p>

497

<p>lesley, i like your pina coladas idea better!</p>

498

<p>anyone want to explain ectoderm, mesoderm and endoderm to me? Like what organs have what tissue etc</p>

<p>B for that MC^?</p>

499

<p>lmao llilliann, you’re extremely creative with those :p</p>

<p>And thanks :stuck_out_tongue: Only problem with the pina coladas one is song starts playing in my head when I read ‘pinocytosis’ </p>

<p>lmao</p>

<p>EDIT: I’ll say the answer after at least 2 or 3 people answer :3</p>
