Which of the following best describes the importance of similar amino acid sequencing of a protein in different organisms? A. The sequence of amino acids in a protein does not directly reflect the DNA that encodes the protein
B. The more differences there are in the amino acid sequencing, the fewer the mutations in their DNA.
C. Fewer differences in the amino acid sequencing of a protein show a greater evolutionary relatedness.
D. The fewer differences there are in the amino acid sequencing, the less closely the organisms will be related.

The circles, or orbits, for electrons are called energy levels. each level can hold only a certain number of electrons. add electrons to each level until you can't add any more. how many electrons can each level hold?

During endocytosis, cells expel what they don't need take in what they need shrink due to loss of water
