A population of snails lives in a large field. As the size of the population grows, individual organisms on one side of the field stop mating with individuals from the opposite side. Which of the following statements is true?

a)Over time, genetic differences between individual snails will increase.
b)Over time, genetic differences between individual snails will decrease.
c)The snail population will eventually split in two and evolve side by side in cospeciation.
This is an example of an increase in gene flow

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

According to the cell theory, which describes cells? a. all organisms are composed of multiple cells. b. all cells have the same structure and function. c. cells are found in everything on earth. d. living organisms are not created spontaneously
