The friction aids in grasping and walking. The friction ridge skin also contains numerous sweat glands, and the pore openings are located along the tops of the ridges. The friction ridge skin does not contain sebaceous (oil) glands or hair follicles.
Answer:
False
Explanation:
We can see the colors of the rainbow, therefore they are visible.
Answer:
Explanation:
They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.
Answer:
12.5 µg
Explanation:
We are given the absorbance from the calibration curve:
A = 0.0182 x + 0.007
A = 0.234 ( It is already corrected, do not need the blank value )
so we can solve for x, the quantity of protein
x = ( 0.234 -0.007 )µg / 0.0182 = 12.5 µg
Note we are given the value for a blank solution but we do not need it for the absorbance of our sample since it is already corrected as stated in the question. If it were not a corrected absorbance ,we will need to correct the absorbance value. The absorbance of the blank is caused by some absorption from the solvent, cuvette, internal reflection, etc.
