Explanation:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
Answer:
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
Explanation:
Answer:
No, in science their meanings are not the same as their everyday meanings.
Explanation:
In Science, Precision and Accuracy are defined as,
Accuracy:
Accuracy is the value which is closest to the known or standard value.
Precision:
While, Precision is the value of closeness of two measured values to each other.
Example:
Let suppose in Chemistry Lab you weight an object as 50 g. While the actual weight of that object is 30 g. It means your reading is not accurate.
On second measurement you find that the object weight is 31 g. This time your reading is not precise.
We know that density is a measure of mass per unit of volume:
Density = Mass / Volume
Therefore, we can calculate for the mass
Mass = Density * Volume
if the density of water is 1 g/cm^3:
Mass = Density * Volume
= (1 g/cm^3) * 94.60 cm^3
= 94.60 g
Calcium acetate [Ca(C₂H₃O₂)₂] is strong electrolytes
<h3>What is the calcium acetate's mode of action?</h3>
End-stage renal disease patients on dialysis who have hyperphosphatemia (excess phosphate in the blood) are treated with calcium acetate. By forming a bond with the phosphate in your diet, calcium acetate causes it to leave your body without being absorbed.
Heat is created as calcium acetate dissolves in water, and as the temperature rises, the solubility of the calcium acetate increases.
When heated, calcium acetate, a somewhat water-soluble crystalline calcium source, breaks down to form calcium carbonate.
