Answer:
46 chromosomes
For humans, this means that during prophase and metaphase of mitosis, a human will have 46 chromosomes, but 92 chromatids (again, remember that there are 92 chromatids because the original 46 chromosomes were duplicated during S phase of interphase).

got it from google hope it helps
Deletion because it worse then a substitution since your deleting something
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
Answer:
Charles Darwin came up with the theory of evolution.
In the square of an element on the periodic table, the number with the highest numerical value represents the atomic number.
<h3>What is the atomic number Z?</h3>
The atomic number is represented by the letter Z and indicates the number of protons (p) in the nucleus of the atom. This quantity is characteristic of each chemical element.
With this information, we can conclude that The atomic number, represented by the capital letter Z, corresponds to the number of protons in the nucleus of atoms (Z = p).
