A young scientist has discovered a new species of grub worm in the Amazon. He would like to explore the possibility that in this grub worm the codon CUC is the start codon and codes for methionine, not leucine as it does in other worms. To date, he has been unable to get his research funded, most likely because

A) worms have been extensively studied and their genomes are simple.
B) the genetic code is universal to all species.
C) worms do not contain homologous genes to humans.
D) worms are difficult to maintain in the laboratory.
E) codons are generally the same in all worms.

18. how do the cells in meiosis differ from the cells in mitosis?

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.

When an object is moving away from you while still making a sound, the pitch of the sound is perceived to a. lower b. unchanged c. fluctuating d. higher
