Answer:
a. At pH 9, the product, p-nitrophenol, will be ionized, the solution will appear yellow in color, and thus can be monitored at the wavelength of maximum absorption for the phenolate ion which is 400nm
Explanation:
In alkaline phosphatase assay, the hydrolysis of p nitrophenyl phosphate to p nitrophenol happens. When the ph is 9, the product which is p nitrophenol would undergo ionization. The solution is going to appear to be of yellow and it can be monitored at a wavelength for maximum absorption of phenolate ions at 400nm.
Option A is the answer to the question.
Answer:
The length of the fence is 22.5ft and the width of the fence is 7.5ft.
Explanation:
To solve this problem we will turn this question into an equation.
The equation for the perimeter of a rectangle is 2l + 2w = perimeter.
In the question we were given the perimeter so we can go ahead and plug this in.
2l + 2w = 60
In the question we are also told that the fence is 3 times as long as it is wide. This means that 1l = 3w. We can now subsitute l for 3w so that we only have one variable.
2(3w) + 2w = 60
Now we can simply use algebra to solve for w.
6w + 2w = 60
8w = 60
w = 7.5
Now that we know the value of w we can find the value of l since we know 1l = 3w.
l = 3w
l = 3(7.5)
l = 22.5
The length of the fence is 22.5ft and the width of the fence is 7.5ft.
Answer:
A.) the transfer of energy through a solid, such as the Earth’s crust
I hope this helps! ^-^
Non-polar because hydrophilic means something can be wetted by water
During the winter solstices, we experience the longest day and the shortest night while during the summer solstices the sun is at its highest point in the sky.
<h3>What is the Solsticest?</h3>
The Solstices is the season that occurs at the moment the earth's tilt toward or from the sun is at a maximum. There are two seasons of Solstices which include the following:
- The winter solstices: This occurs when the sun is directly over the Tropic of Capricorn causing us to have the shortest day and longest night of the year.
- The summer solstices: The sun is at its highest elevations.
