The evolution of new traits is possible because of
A selection can anticipate future environmental changes
B mutation and recombination during sexual reproduction produce new genotypes
C selection can act on the expression of existing traits in new tissue or at new development periods leading to novel functions
D the last two are both reasons why selection can lead to new traits

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
