Step by step
Solved in 2 steps
- Pharyngeal slits are which of the following? Question 24 options: a) Openings in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth. b) Elongations of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates. c) Flexible, rod-shaped structures that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species. d) Tissues that produces thyroid type hormones. e) Hollow tubes that develops from ectoderm. Develops into the central nervous system.Discuss the differences between the Turkana Boy and the Dmanisi fossils.
