Liver cells because it uses the most energy than the other choices
Answer:
D) choose the tree that represents the fewest evolutionary changes, either in DNA sequences or morphology.
Explanation:
Parsimony is a concept applied while constructing a phylogenetic tree. According to it the best tree is constructed by fewest evolutionary changes, either in DNA sequence or morphology. Complicated changes should be present as less as possible in a tree.
For example, suppose vertebrate relationship can be explained using two trees. Tree A has six evolutionary changes and evolution of bony skeleton occurs once. Tree B has seven evolutionary changes and evolution of bony skeleton occurs twice at different spots. Tree A will be preferred because it explains the vertebrate relationship in a less complicated way than Tree B.
Answer:
Plants are multicellular eukaryotes. They have organelles called chloroplasts and cell walls made of cellulose.
Plants also have specialized reproductive organs.
Almost all plants make food by photosynthesis.
Life as we know it would not be possible without plants.
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
Answer:The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.
Chronological order is a way of arranging actions, events or things according to the time they occurred. It is demonstrated by showing what happened first, what went on next, what came about in the succeeding occurrences,
