Question 6. Explaining concepts, predicting and diagraming outcomes of musculoskeletal systems, 20 points   Give an in-depth explanation written in paragraph form or drawn in a diagram for the following questions.   You are an exobiologist in the near future working for SpaceX (don’t worry, Elon is long gone), studying the planet TOI-715b which orbits the star TOI-175 approximately 138 light years from earth. TOI-715b is 1.55 times the diameter of earth and a mass of 3.02 times that of Earth. This planet has an oxygen (~30%)/nitrogen (70%) atmosphere with traces of carbon dioxide, and sulfur. It has saltwater seas and landmasses covered with carbon fixing analogs to Earth vegetation. You are, however, interested in an organism that has elements of both hydrostatic skeletal and endoskeletal structures. This organism is pentapedal (5-appendages) and actively hunts/chases its prey (can be aquatic or terrestrial)   Explain or diagram the similarities and/or differences between a hydrostatic skeleton and an endoskeleton, including how muscles exert forces on the skeleton to help the animal move given it has elements of both skeletal types. (6 pts) Apply what you know about the constraints that higher gravity may have on the organism’s form, ability to move, and gas exchange/circulation. (6 pts) Draw the organism including any skeletal systems, gas exchange/circulatory systems, muscle types/arrangements, or specialized features that this organism needs to survive in the environment of TOI-175b.

Question 1: Compare and Contrast – Sensory and nervous systems, 15 points   Give an in-depth explanation written in paragraph form for the following questions. Your answer must be in paragraph format or you will automatically lose 10 points on your answer regardless of the content. Paragraph should be ~300-500 words and answer all of the parts of the question completely.   A. Compare & contrast the role that both (1) active and (2) passive transport play in membranes of animal sensory and nervous system. Make sure to discuss both active and passive transport, including chemical/ligand and voltage gated channels. Be sure to describe the structure, function, and location of these proteins in the nervous & sensory system. Additionally, given how sensory cells respond to stimulus, what would the consequence be if damage occurred upstream or downstream of that sensory cell neuron? (9 pts) B. Application: Motor neurons release the neurotransmitter acetylcholine (ACh), and acetylcholinesterase degrades ACh in the synapse. If a neurophysiologist applies a large amount of onchidal (a naturally occurring acetylcholinesterase inhibitor produced by the mollusk Onchidella binneyi) to a synapse, what would you expect to happen?
