BIO 235 Assignment 2 Questions and Answers 100% Pass With regards to effort and load, describe the main difference between a lever operating with a mechanical advantage versus a lever operating at a mechanical disadvantage. - Answer- a. Mechanical advantage- If the load is closer to the fulcrum and the effort farther from the fulcrum, then only a relatively small effort is required to move a large load over a small distance.Mechanical disadvantage- If the load is farther from the fulcrum ...

In temporal summation, a single presynaptic neuron stimulates the creation of action potentials in a postsynaptic neuron when it correct answer: Fires at a fast enough rate that the sum of EPSPs in the postsynaptic neuron moves above threshold A postsynaptic neuron responds to neurotransmitters released by a presynaptic neuron by creating correct answer: Either EPSPs or IPSPs Wallerian degeneration refers to correct answer: Degeneration of the distal end of axon and myelin sheath after ...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...

A female infant is born with several hundred oocytes, each one genetically unique. This is due to - independent assortment and random crossover in meiosis. A low secretion of luteinizing hormone (LH) in the otherwise normal male adult would cause - decreased testosterone secretion A man has been told that he is not synthesizing enough follicle-stimulating hormone (FSH), and for this reason he may be unable to father a child. Choose the correct statement to explain this problem. - FSH stimu...
