Answer:
O celacanto era há muito considerado um "fóssil vivo" porque os cientistas pensavam que era o único membro remanescente de um táxon conhecido apenas por fósseis, sem relações estreitas vivas, e que evoluiu para aproximadamente sua forma atual há aproximadamente 400 milhões de anos.

Answer:
c. The P allele is less frequent in the US than the p allele.
Explanation:
If people with the heterozygous genotype "Pp" present polydactyly, only people with the genotype "pp" will not present polydactyly. Since 99.9% of the population do not exhibit polydactyly, then it can be concluded that the "p" allele is much more frequent in the US than the "P" allele.
Therefore, the answer is:
c. The P allele is less frequent in the US than the p allele.
A class of lipids used as chemical messengers, to signal cells to undergo changes, is called Monoglycerides. Its a class of glycerides which are composed of molecules of glycerol linked to fatty acid by easter bond.
Monoglycerides are the type of glyceride and that made up of glycerol and one fatty acid chain. Triglycerides are very similar expect they have three fatty acid chains. Mono and diglycerides may be manufactured through the reaction of plant or animal derived fatty acids with glycerol which breakdown plant or animals which derived fats and oils.
Lipids such as steroid hormones that serve as chemical messengers between cells , tissues and organs and other communicate signals between biochemical system within a single cell.

Answer:
Anaphase
Explanation:
During Anaphase the chromosomes separate and move along the spindie fibers to opposite ends of the cell.
All of the above points are valid for fossils' contributions in understanding the process of evolution. They allow us to study the ancestry, we can see the homologous organs or structures, if fossils are well-preserved; different fossils can lead us to follow the cycles of the changes that occurred during macroevolutions, and fossils can be used to study different populations which had different body structures for surviving in different environmental conditions.
