Part B - Permeability of the lipid bilayer Some solutes are able to pass directly through the lipid bilayer of a plasma membrane, whereas other solutes require a transport protein or other mechanism to cross between the inside and the outside of a cell. The fact that the plasma membrane is permeable to some solutes but not others is what is referred to as selective permeability. Which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism?
a) proteins
b) water
c) ions
d) sucrose
e) lipids
f) carbon dioxide
g) oxygen
Answer:
b) water
e) lipids
f) carbon dioxide
g) oxygen
Explanation:
Diffusion is the means by which molecules like water, lipids, carbon dioxide and oxygen easily move across the lipid bilayer of a membrane directly without the use of a transport protein or any another mechanism.
Diffusion is the way or means through which molecules( such as gases or liquids) move across a membrane from and region of higher concentration to a region of lower concentration.
Before a molecule can pass through the semi permeable membrane without the use of any mechanism or transport protein, it has to be:
a) a small molecule
b) an uncharged molecule
c) an hydrophobic molecule

The Thermal radiation is one of "3 mechanisms who allows to bodies exchange energy".
The thermal radiation formula is given by:
Where 
If we solve for P we got:
Since we have a baseball ball considered as a sphere the superficial area is given by:
Solution to the problem
And if we replace this into our equation of P we got:
And we can reorder this like that:
We can convert the radius to meters and we got:
Now we can convert the temperature to Kelvin and we got:
the emissivity given
And now we can replace into the formula for P and we got:
