How can weak acids and weak bases cause pH stress to cells 2 pts A At certain pHs both weak acids or weak bases will be uncharged and thus are small uncharged molecules that can diffuse across a membrane and cause pH stress inside the cell 5 Only weak acids can cause stress by diffusing across a membrane at low pH Weak acids and weak bases do not cause stress If a cell has transporters that are not well regulated weak acids or weak bases can accumulate inside the cells and cause stress

Didi is the Komodo dragon at the Atlanta Zoo She is a female and maybe one day she will be able to make offspring on her own Is this possible yes but she could only have male offspring since the embryo will come from an unfertilized egg yes it can happen yes and she would only be able to produce viable homozygote male offspring no it cannot happen since Komodo dragons are reptiles and they reproduce only sexually yes but the offspring would be haploid since females are the heterogametic sex in this species
