First, find the greatest common factor of the two terms- in this case, 21. Then divide each term by the GCF. 42q/21=2q and -21/21=-1 So, 21(2q-1)
Most likely the one with the most descendants. Evolutionary science generally deals with the passing on of genes, and that frog would have reproduced the most and would therefore have been the most successful.
The mice would be half heterozygous for black, and half white.
Sorry, our answers posted at the same time. I didn't mean to seem excessively insistent.
I think that the apostrophe would be redundant
The "that of" makes the sister possessive- no need to be possessive twice.
No- It would be: Her coat is different from that of her sister.
It's actually 4.5*10^-6. 5=pKa+log(10/22.22)
I plugged those numbers into the HH equation and came up with 2.22*10^-5 for the Ka. Does that sound right?
At the first point where he stopped and measured the pH, the H+ ion concentration is 1*10^-5 and the OH- ion concentration is 1*10^-9. This is as far as I've gotten, I can't figure out what to do with this information.
