involved in the process
,E) Glucose would be produced at such a high concentration that it would poison the
chloroplast. - ANSWER-C) Too much O2 would be produced in the chloroplasts,

increases. Which of the following statements provides the best explanation for this
change?
A) Individual grasshoppers with longer legs survived better than those with shorter
legs.
B) The grasshoppers needed to have longer legs, so natural selection gave it to
them.
