An ecologist catches 100 frogs from a pond, marks them, and releases them back into the pond. after a few days, another 100 frogs are captured and 10 have the marks on them. how many frogs are in the pond?

answer: i say it foxes

explanation:

you need to give us the answer options to for me to offical decide.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
