Does other animals have faster nerve speeds?

The speed of nerve transmission depends on the size of the nerve axon, the length of it and whether it is effectively insulated by myelin. There are a vast number of different kinds of neurons in each animal, and for some there are ...

I am having difficulty identifying this structure.

This image is from a spinach chloroplast and has been made using a Transmission Electron Microscope microscope. I have been given this image to identify which has been took by a TEM. I have been for quite a while been comparing and contrasting many different ...

Re: Is complexity inevitable?

... of a mutated FOXP2 gene. They seem just as complicated as us, but they aren't superior organisms without the benefit of transmitted knowledge. The transmission of knowledge seems to be why, for us, intelligence is clearly worth the cost. A human can focus on learning science rather than on doing ...

is mosquito saliva hypotonic to plasma? HIV concern?

... concerned about HIV. If the mosquito had just fed on an HIV positive individual, and then gotten into my eye (which is a documented method of transmission), could I potentially be infected? I know that human saliva is hypotonic to plasma, which effectively prevents any transmission of HIV. ...

Why do neurones only have one axon?

... neurones at a synapse and transmit signals very fast. I think what you actually want to know is would having multiple axons on a neurone speed up transmission of a nerve impulse and the answer to this i do not believe to be yes because neurones are insulated ( some are anyway) with a substance ...
