Apopulation of purple gorillas feeds entirely on plants. but some of these gorillas are good at digesting plant a, while others are good at digesting plant b. still other purple gorillas are good at digesting plant c. what might be an advantage of a single population of animals, such as the purple gorilla, having a very large amount of variability surrounding certain traits? a. there is no evolutionary advantage to this situation. b. it increases the chance that some members of the population will survive under changing environmental conditions. c. it makes it more difficult for poachers to hunt them. d. it makes it less likely that the population will split into different species, when selective pressures are increased.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
