Assertion and Reason
Directions: The following question has two statements, Assertion and Reason.
Answer the question by choosing any one of the four responses.
Assertion: Brain and spinal cord are called modulators.
Reason: Their neurons receive a stimulus and set up a sensory impulse.

dear experts , i have some questions here
1.the hormone which when deficient causes cushings syndrome .
2.give two points of difference between cretenism and myxoedema .
3.can there be dna replication without cell division . comment.
4.enumerate the different types of nerve fibres depending on nature and function .
5 . a person has excessive thirst and production of large amount of urine . the doctor did not advice him to stop taking sugar . name the disese and explain what happens in it .
6.difference between glomerular filtration and ultra filtration .
please i need these answers by tomorrow night .its a request .
