Insulin Basics: How Insulin Helps Control Blood Glucose Levels. Insulin and glucagon are hormones secreted by islet cells within the pancreas. They are both secreted in response to blood sugar levels, but in opposite fashion! Insulin is normally secreted by the beta cells (a type of islet cell) of the pancreas
I wanna say it would be 1 would be A 2 would be C 3 would be D 4 would be B and 5 would be E
hope this helps
Explanation:
The volumetric flow rate of water will be as follows.
q = 
= 0.0378 
Diameter =
= 0.2032 m
Relation between area and diameter is as follows.
A =
=
= 0.785 x 0.2032 x 0.2032
= 0.0324
Also, q = A × V
or, V = 
= 
= 1.166 m/s
As, viscosity of water = 1 cP =
Pa-s
Density of water = 1000
Therefore, we will calculate Reynolds number as follows.
Reynolds number =
=
= 236931.2
Hence, the flow will be turbulent in nature.
Thus, we can conclude that the Reynolds number is 236931.2 and flow is turbulent.
Atoms in covalent bonds do combine so as to be stable. As covalent bond consist non metals e.g O2 in this example each atom has vacance of 2 orbitals/ electrons so shairing electrons result their stability
