Chloe’s mother wants to have another child. However, she is concerned that a second child might also have CF, so she encourages

CF is a recessive type of disorder which means that both parents must carry the gene in order for the child to inherit the disease. If the child only inherits 1 copy of the affected gene, then the child becomes a carrier. Carriers do not manifests symptoms of the disease but they can pass the disease to their children.
With both parents as carriers, they will have the following chances: 50% carrier children, 25% affected child, and 25% normal child.

<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!

Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.

Active Transport 
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).

Phagocytosis 
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.

Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.

Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>

For example

GGC is your DNA

CCG is your RNA

And your amino acid would be PRO

2.

AAT --> AAU -->ASN

DNA ---> RNA --> AMINO ACID

3.

Which molecules are not able to permeate the cell membrane
max2010maxim [7]

Answer:

Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.
