The letter order should be 1,4,2,3
1 goes to Q1
2 goes to Q4
3 goes to Q2
4 goes to Q3
Answer:
Joseph Lister successfully introduced carbolic acid (now known as phenol) to sterilise surgical instruments and to clean wounds. Applying Louis Pasteur's advances in microbiology, Lister accomplished the use of carbolic acid as an antiseptic, so that it became <u>the first widely used </u><u>antiseptic in surgery</u><u>.</u>
Cereal companies are blamed for putting too much sugar into their products, which causes obesity. This is bad for them, as it would stop people from bying their products. So they would have an interest in study showing that this is not the case: the study would be a self-interest study (the correct answer) and therefore not be reliable
Ophi is the fear of snakes, gloss is the fear of public speaking, acro is the fear of heights, muso is the fear of mice and avio is the fear of flying. all of these are the most common phobias(fears) world wide!
Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
