what do you have do in this question bro
Explanation:
I will help you do it
Axons with large diameters conduct impulse faster than those with small diameters. Also Myelinated axons conduct impulse faster than unmyelinated axons. Axons with the largest diameter are all myelinated, therefore they are capable of salatory conduction (Impulses jump from one myelinated node to another). The smallest diameter axons are unmyelinated, so their conduction is continuous.
I hope this helps. :) :)

Chemotherapy is a process of intense treatment for cancer. It includes one or more anti-cancer drugs. However, most people become sick after they go through with chemotherapy. This can last for days or longer. Hopefully, nobody gets cancer and has to go through this procedure.
<u>Answer</u>:
Vestigial organs are those organs that were present in the past ancestors but absent in their present generations. Vestigial organs are not leftover of evolution because they are evolved to perform a different function.
<u>Explanation</u>:
For example, an appendix is considered as a vestigial organ but it helps in storing good bacteria and plays a vital role in the immune system. These vestigial organs are the product of changing the environment and adaptation to the changing environment. Due to natural selection some specific traits have been passed down to generations which helped the animals to survive in those conditions. The other examples of vestigial organs are wisdom teeth coccyx, tonsils, several genes in the chromosomes and our hair.
