I need help with 1 and 2...I hope you can see the picture
thanks

1. cell m is not able to bind hormone a, as a result hormone b is not going to be produced and there will be a buildup of hormone a.

2. cell d is not able to bind hormone b, as a result hormone b will be building up and hormone a will decrease over time.

Question 1:
Look at Cell M. The receptor is not correct (it is "bowl shaped, not inverted triangle. Because the receptor for the hormone is mutated, it can not bind the Triangle hormone (Hormone A). That means the will be a build-up (an excess) amount of Triangle hormone (Hormone A) in the organism.

Question 2:
Look at Cell D. The receptor is mutated. It is "bowl" shaped, not a rectangular shape for the rectangular shaped hormone (Hormone B).
Because Cell D cannot bind the rectangle hormone (Hormone B), it will build-up in the organism. The Triangle shaped hormone (Hormone A) will NOT build up in this organism because there still is a proper inverted triangle receptor on Cell M that will remove (and metabolize) that hormone, keeping its concentrations at normal conditions.

Hope that explains it for you.
