Inhaling carbon monoxide reduces the ability of red blood cells to carry oxygen. This can lead to brain damage. The respiratory, circulatory and nervous systems <span>interact in this situation.</span>
Answer:
An acid is a substance that donates hydrogen ions. Now there are more hydrogen ions than hydroxide ins in the solution. This kind of solution is acidc. A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions moves the other way.
Explanation:
Value of pi = 3.14
Radius of the semicircle = 6 cm
Diameter of the semicircle = 6 * 2 cm
= 12 cm
Perimeter of a semicircle = pi * Diameter *(1/2)
= 3.14 * 12 * 1/2
= 3.14 * 6
= 18.84 cm
From the above deduction, we can conclude that the perimeter of the semicircle in question is 18.84 cm. I hope that this is the answer that has come to your desired help.
Answer:
Objective Lens Magnification = ×100
Explanation:
In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.
In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.
Total Magnification = (eyepiece lens magnification) × (objective lens magnification)
1000 = 10 × obejcetive lens magnification
Dividing both sides by 10
Objective lens magnification = 1000 ÷ 10 = 10
∴ Objective lens magnification = ×100
