The elements of heavy metals are used to absorb electrons in electron-dense stains.
<h3>
What are heavy metals?</h3>
A heavy metals are generally defined as metals with relatively high densities, atomic weight and atomic number.
They toxic and poisonous in nature. They occurs naturally and are very essential to life.
Arsenic, cadmium, lead, copper, nickel and mercury are the most commonly used heavy metals.
Electron staining means to absorb heavy metals of high scattering power to biological specimens which exhibit a small scattering power for electrons.
Thus, the elements of heavy metals are used to absorb electrons in electron-dense stains.

Answer:
3.01 x 10 to the power of 6
Explanation:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 3,010,000
New Number: 3.010000
Step 2
Now, to find b, count how many places to the right of the decimal.
A balanced equation is a prime example of the law of the conservation of mass as the number of atoms in the reactants is consistent with the number of atoms in the reactants meaning the amount of matter has not changed and no mass has been created or destroyed hence obeying the law.
Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California's San Andreas fault is a transform boundary. So its true
