Answer:
A rotting log is nonliving. However, it can have mold, lichen, or fungus growing on it, which is not the log itself. Those three things are living. And though the log was once a living tree, at it's current state, it is nonliving.

Vision plays a vital role in perception of objects. Focal vision and prescient is the vision that identifies precise objects. Focal imaginative and prescient normally includes interest, even as ambient capabilities are greater reflexive in nature. The focal mode in preferred solutions the query of "what" about items perceived.

Explanation:
Definition of atomic radii:
The atomic radius is the distance between center of two bonded atoms.
Trend along period:
As we move from left to right across the periodic table the number of valance electrons in an atom increase.The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases.
Trend along group:
In group by addition of electron atomic radii increase from top to bottom due to increase in atomic number and addition of extra shell.
In this way the strontium atom will bigger than the calcium because ts atomic number is greater then than the calcium while the atomic number of beryllium and magnesium are less than the calcium that's why their atomic sizes are smaller.
While scandium is in the same period that of calcium and present after the calcium that's why because of greater nuclear attraction its size is smaller.
