Answer:
Option B, 
Explanation:
Given-
The average surface area of one foot pad of an elephant is

Weight of an Asian elephant is
newton
As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.
Thus, pressure on one foot pad of elephant is 

Hence, option B is correct answer
Answer:
b) there are 56 deer in 1000 acres of area.
Explanation:
If a person has 1000 aces of land and a local wildlife biologist tell him that on every 18 acres only one deer is present so in 1000 acres there are 56 deer are present.
calculation;
1 deer ------ 18 acres
x --------- 1000 acres
by cross multiplication, we get
18 x = 1000
both side divided by 18, we get
x = 55.5
by rounding off we get
x = 56
It will ultimately affect every branch of the food chain, as protists are the basis of it all.

Answer:
16) 6 electrons
17) 6 protons
18) 6 neutrons
19) 4 electrons
20) 6
Explanation:
There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.
