Answer:
focal length depends on the radius of curvature, the refractive index of lens material, and the medium's refractive index in which the lens is placed
There are organelles in the plant cell that the animal cell does not have. Plant cells have rigid cell walls and animal cells have flexible cell membrane. Plant cells contains chloroplasts, which is something animal cells don't have. Also, large, liquid filled vacuoles can only be found in plant cells, and they can occupy up to 90% of a cell's volume. By looking at the cell and see if they have any of these characteristics determines if it is plant cell or animal cell.
hope this helps.

<h2>
The number is 42 </h2>
Explanation:
Let the digits be a and b.
The sum of the digits of a two-digit number is 6
That is
a + b = 6
When the digits are reversed, the number decreases by 18
ab - ba = 18
We need to find the number
Since ab - ba = 18, we know that a is greater than b.
Take a = 4
4 + b = 6
b = 6 - 4 = 2
That is the number is ab = 42
When it is reversed the number is 24.
42 - 24 = 18, hence correct
The number is 42
