Answer:
I would think the correct answer would be B and D.
Explanation:
The information the institutions gathered doesn't tell whether the temperature increased or decreased so it couldn't be A. And the data that is gathered by each institute is similar to one another, so it couldn't be C. Therefore, you're left with B and D.

The body's main requirement of iodine is in the thyroid gland. Therefore, iodized salt would have no effect on any cases of Graves' disease as the thyroid gland is already overactive in this disease.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
Answer : The pH of a 0.1 M phosphate buffer is, 6.86
Explanation : Given,
Concentration of acid = 0.1 M
Concentration of conjugate base (salt) = 0.1 M
Now we have to calculate the pH of buffer.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Therefore, the pH of a 0.1 M phosphate buffer is, 6.86
#4 and #5:
To find pH given concentration of H+ or H30+
pH = - log (H+ or H30+ M)
To find pH given concentration of OH-
Since you already found the pH for this (in #4), you subtract #4's answer from 14.
14 - (pH) = pOH
