Biology > Cell biology > Passive transport
There are different types of transport in the cell that can be classified into two groups: passive transport (which does not require energy) and active transport (which requires energy because it goes against the concentration gradient).
Diffusion is a type of passive transport and it does not require energy, it can be divided into simple diffusion (molecules pass through the membrane without the help of any channel) and facilitated diffusion (molecules pass through the membrane with the help of a protein channel).
Facilitated diffusion will transport certain molecules and simple diffusion others. Larger, polar and charged molecules will need help to cross the membrane, so they will do so by facilitated diffusion. Therefore, the answer is D.
Answer:
Yes or no
Explanation:
If the disease is genetic then the answer is yes because identical twins have the same genes.
If the disease is viral or bacterial than the answer is no because identical twins are growing in a different environment and facing different bacteria and viruses. So if one is sick it's not compulsory that the second one is also sick it purely depends on the environmental conditions.
