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 .

6.difference between glomerular filtration and ultra filtration .
please i need these answers by tomorrow night .its a request .
Explain the following processes:
(a) Polarisation of the membrane of a nerve fibre
(b) Depolarisation of the membrane of a nerve fibre
(c) Conduction of a nerve impulse along a nerve fibre
(d) Transmission of a nerve impulse across a chemical synapse

(a) Releases hormones during emergency situations.
(b) Hormone released by this gland helps in the differentiation of T- lymphocytes.
(c) Deficiency during pregnancy leads to cretinism.
(d) Present in close contact with hypothalamus and controls other endocrine glands.
(e) Helps in maintaining the diurnal rhythms of sleep-wake cycle.
