Answer The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all. ... Larger molecules such as glucose require a specific transport protein to facilitate their movement across the cell membrane.

Answer:
10/9x
Explanation:
Start with:
8x/3x+6 // 12x^2/5(x+2)
Factor out 3 then multiply the ricprocal of that fraction:
8x/3(x+2) * 5(x+2)/12x^2
Reduce the expression with x+2, then x,
8x/3 * 5/12x
Reduce numbers w/ GCD 4
2/3 * 5/3x
Lasty, multiply the fractions [multiply numerators&denominators seperatly]
2*5/3*3x
and you get...
10/9x [yayyyy!]
Answer:
A. Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
Explanation:
Energy, as stated in this question, can be of two types namely: kinetic energy and potential energy. Kinetic energy is the energy due to motion i.e the energy used to transport solute etc.
On the other hand, potential energy is the energy due to position like the energy stored in the covalent bonds of a molecule. Based on this question, the fact that triglycerides (a type of lipid) store about twice as much energy as polysaccharides (carbohydrate) is evidence that POTENTIAL ENERGY is stored in covalent bonds.
The way water is cycled through the air and the atmosphere it is how we retain clean and good water in our planet.
