Answer:
They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
Explanation:
The Nitrogen is the component <span>of the atmosphere that provides great stability due to its own stability as a molecule.</span>
The six most common elements inliving things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Atoms of these elementscombine and form thousands of large molecules. These large molecules make up the structures of cells and carry out many processes essential to life.
<span>When the earth spins in a certain direction, the ocean currents move in the opposite direction, sort of like when a car moves forward you are pulled backwards. However, there would still be wind and the gravitational pull of the moon which causes currents. The rotation of the earth just sort of "accents" these. So as a result, you would have many more smaller ocean current cycles.

Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
