Answer:
<em>B: The drug is a small charged molecule</em>
Explanation:
Substances can passively diffuse in and out of the cell via the cell membrane in two ways;
- Simple diffusion
- Facilitated diffusion
The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.
In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.
Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.
<em>Correct option: B</em>
I believe its C-Mitochondrion.
It the powerhouse of the cell.
-Steel jelly
The best and most correct answer among the choices provided by the question is the third choice "neap"
Neap tides<span> occur twice a month when the sun and moon are at right angles to the Earth. When this is the case, their total gravitational pull on the Earth's water is weakened because it comes from two different directions.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
The number of oxygen is more in carbohydrates than in fats, usually. For instance, the chemical structure of glucose is C6H12O6 compared with oleic acid which is C18H34O2. Carbohydrates and lipids are biomolecules that contribute to cellular and biological processes. These are important because these are the source of energy, replication and reproduction among cells.
