those ****ing fish :angry: i put legal restrictions on fishing amounts, manually modifying or placing fish populations in oceans/rivers, greater encouragement by governments for vegetarianism, and some other stuff I can't remember rn. what about that rhyscosa single-cell organism, or whatever it was called..??


For the single celled organism I talked about the fact that it would burst since it doesn't have a cell wall that's why it had that special vacuole

Did anybody struggle with the inheritance question about acatalasia? I could not understand how to do a punnet square when one parent had only one gamete drawn -_-


The dieseasw was not sex linked the only reason that it was one gamete is because it was XX so it has x and make had XY so it had X and Y it took me a whole to figure that question out but the punnet square produced Bb Bb and bb bb

the parent only had one gamete down because it had two of the same gamete, the recessive gene that shows acatalasia. so one parents was Bb and the other was bb.
I was confused for a second but realised what was going on.

Also how did everyone find the multiple choice?

yup, same, kinda said having a contracting vacuole is pointless in a cell with a cell wall because the cell wall gives turgor to the cell and would prevent its vacuole from over-expanding anyway
