**SAT 2 Biology Discussion Thread Oct 2015**

why do you say that? (im not saying youre wrong i just wanna know why) @bobo135

@goldy1121 actually looking back on it A works too doesn’t it? I put D since only 10% of the energy gets transferred to the next level, and i think losing 90% qualifies as “most energy is lost”

that was a dumb and super vague question

i agree

How about this one? (Molecular)
I. TAT is a protein
II. glucocorticoids are proteins (I know this isn’t true)
III. enzyme for TAT mRNA synthesis is active before protein synthesis inhibitor is added

I and III

do you remember a question about the carbon atom? and about an affected organelle that hinders enzyme production?

I and III what? @potterismylife

does anyone remember the answer to the question that asked how inhaled air is different from dry, atmospheric air?

@goldy1121 oops sorry that was in response to the question above my post

@bobo135 inhaled air has moisture, something abt a trachea

its humidified @bobo135

@potterismylife it has more humidity? that’s what i put

@goldy1121 p sure it was that carbon makes four covalent bonds, don’t remember that organelle question but sounds like it’d be ribosomes

How about the one for that heterozygous disease: 2/3 of offspring had the disease and 1/3 didn’t. What caused this?

@MiscTroll the zygote of homozygous dominant isn’t viable

@potterismylife whew thats what i put too

OOOH WAIT @goldy1121 do u mean the question where there was a cell that was meant to secrete enzymes but bc of a mutation all of the proteins remained inside of the cell instead of being secreted?

bc the answer to that one was golgi apparatus

Any curve predictions?

What was dat placenta question? I think it was which of the functions EXCEPT.

Mixing of fetal blood with mothers blood. Blood doesn’t get mixed. Plasma does.
