PLEASE, PLEASE, I NEED HELP: From the early 1700s to the modern day, how did various lines of evidence refine scientists’ understanding about the ancestry of Cetaceans? (I need an explanation for each one)(I will give brainiest) a. Anatomy

b. Fossils

c. Embryological Development

d. DNA

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.

c is the answer. hope this
