Which of the following is a correct example of natural selection? A. The DNA of a frog changes due to radiation, chemicals, or some
other mutagen.
B. A population of frogs experiences a change in allele frequencies as
more frogs immigrate into the population.
C. Poisonous frogs with warning coloration are less likely to get eaten
by predators. Individual frogs therefore develop warning coloration
and poison during their lifetimes. These acquired characteristics are
passed on to their offspring.
D. Certain members of a frog population are better camouflaged, so
they survive and reproduce more, passing on their color genes.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

idk

explanation:

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
