What did you guys put for the question in Bio M that asked what most likely happened to mutant 2 of E. Coli? I was stuck between that they could digest lactose without galactosidase and a nucleotide sequence error
@elsa96l I put nucleotidic error.
With the gene for galactose
Was uterus an answer for one of the questions?
Yas I put that.
I put it for one too
Did anyone else get (A) for #84, the question about antibodies on the M section? I thought it was right but the amount of people here who got tripped up on it is worrying me…
It said something about finding the correct DNA combination to produce a working antibody.
This test was really hard in my opinion. I made a 670 in Barron’s, 750 on blue book test, and I think this was harder than both I’m not gonna lie… Karyotype question was tough even though it probably shouldn’t have been, and the one with the dinosaur was killer, so was the one about the enzyme (was the answer “it was used up”? Because I know enzymes can be reused so I don’t know but that’s what I put) and yeah I omitted 9 so I’m not the happiest.
Poor freshman here… Got destroyed with these questions, most likely retaking if the curve isn’t generous :(( omitted 5 and probably got like 6-8 wrong
Yes, the one with the enzyme was that the substrate got used up.
The karyotype ones weren’t a problem as long as you realized that there were 24 pairs of chromosomes (it tried to trick you by making you think there were 23). 24 in a gamete, 25 in the abnormal gamete, and 48 in a somatic cell.
Wait I’m pretty sure that the enzyme one was that the active sites are all filled
So it goes at a constant rate
same I put all active sites filled
The increasing amount of product produced indicates that the enzymes are constantly catalyzing the reactions rapidly because the product can only be produced after the substrate has become the product and has left the active site.
If the answer were indeed that all active sites were filled, the graph would show a flat line for the first few seconds (the enzymes catalyzing the reactions and the active sites all filled) and then shoot up after that.
I think it was substrate was used up because the rate went to 0 ( the graph was total amount of product vs time, not rate vs time)
I also think that the enzyme one was that the active sites are all filled
Did anybody get 0.001% for the energy transfer rate in 4th level? since energy flow starts from the sun.
It was 0.1%.
Yeah it is that the active sites are used up because as the substrate increases the active sites are filled and keep making products until are the products keep being made at an equal amount. Because as the substrate is being added it makes products Rt, but after a while if too much substrate is added, then the substrates will have to wait their turn to make the product, that is y the rate is 0 because they all make a bunch of product, I understand y u chose ur choice, but pr says that it is that all the active sites r filled.
Cuz they had a similar q
