Answer:
The cell membrane determines what goes in and out of the cell.
Explanation:
Answer: 18
Explanation:
This molecule, called ammonia, is a group of atoms held together by chemical bonds. In this example, the atoms (smallest pieces of matter) are nitrogen (N) and hydrgoen (H)
The number 6 indicates the number of moles of the NH3 molecule. A mole is the unit of measurement used to measure the number of atoms or molecules. One mole is equal to 6.02214078×10^23 of the same things.
And since there are 3 Hydrogen atoms found in each mole of ammonia, and there are 6 moles of amminia, then 6 x 3 = 18 atoms of hydrogen.
No 6 is common for N and H. 3 is only for H(Hydrogen).
For finding the number of hydrogen atoms we should multiply 6 with 3
So, 6*3 = 18. So there will be 18 hydrogen atoms in 6NH₃
Answer:
The correct answer would be the organismal theory.
The three main principles of the cell theory are:
The organismal theory was developed as a counter argument towards the cell theory.
One of the principles of this theory states that "cells are the basic building blocks of life but don't constitute life itself". For example, cells removed from a multicellular organism require specific life support systems in order to keep them alive.
