Biology fits into the category of social science
It looks like the integral is

Let's close the loop by adding a line integral over the line segment joining (1, 4) to (0, 0). Then the closed loop is the triangular region
T = {(x, y) : 0 ≤ x ≤ 1 and 0 ≤ y ≤ 4x}
Since the integrand has no singularities over or on the boundary of T, we have by Green's theorem

Compute the double integral:

From this result, we subtract the line integral over the extra line segment we added. Parameterize this path by
C' : {(1 - t, 4 - 4t) : 0 ≤ t ≤ 1}
The line integral over C' is


so that the line integral over C alone is 60/3 - (-44) = 64.
One of the examples from the text that can be regarded as clear, logical and sincere is:
- The speaker said, this nation would endure, revive and prosper.
He goes to say that they only thing that they had to fear was fear itself. He said this to show that fear may keep them from advancing when they should have done so.
The president used the words such as revive to show that the nation was still capable of enduring and coming out of the dark times that they were in.
From these words we can see that the president was logical and also sincere in what they were passing through and how they were to overcome it.
<h3>What is a clear, Logical and sincere quote?</h3>
These are words that are said to convey the truth about given situations in simple and well defined terms.
Such words are said to show that the speaker has good reasoning about the subject.

What can cause a decrease in calcium absorption is; High Levels of Sodium
<h3>What causes poor calcium absorption?</h3>
Calcium absorption varies by type of food. The absorption of calcium from dairy products and fortified foods is about 30%.
Some compounds in plants like oxalic acid and phytic acid can decrease calcium absorption by forming indigestible salts with calcium, thereby decreasing its absorption.
Now, we can conclude that calcium absorption is decreased by high levels of sodium because excessive salt can interfere with calcium absorption.
