Answer:
a. VIP (vasoactive intestinal peptide)
Explanation:
The enteric nervous system (ENS) is one of the main divisions of the autonomic nervous system (ANS) together with sympathetic and parasympathetic nervous system. This system consists of neurons that regulate the function of the gastrointestinal tract (GI).
Inhibitory interneurons that are part of the enteric nervous system also known as Dogiel type I neurones achieve their inhibitory transmission via nitric oxide, adenosine triphosphate, vasoactive intestinal peptide (VIP) and pituitary activating cyclic AMP. They usually act directly on smooth muscles of GI.
If we had 263 ml of mercury (volume) the density of the mercury is 13.55
g/cm”
Mass = Density x Volume (use image attached as guide)
Mass = 263 x 13.55 = 3563.65
Your mass should be 3563.65
Long ears have to be dominant:
If this IS true then these would be your 'parents':
L = long ears
l = curly ears
LL x ll
If you cross the homozygous recessive curly eared rabbit (ll) with homozygous dominant long eared rabbit (LL) you would get 100% Ll - all would look long eared.
