The students hypothesis would be something like:
"I believe that some seeds must be exposed to cold before they germinate."

But what the student is missing is some samples from seeds that are not exposed to cold, since they are trying to figure out whether the seeds should be exposed to cold or not.

Is the following statement true or false? Explain your

Marrrta [24]

Answer:

False.

Explanation:

Cell membrane is made of the lipids and proteins with the attached moieties of carbohydrates. The plasma membrane is the selectively permeable membrane that allows the diffusion of some selected particles only.

The transport along the cell membrane depends on the size and the hydrophobicity of the molecule. The size of oxygen is although higher than magnesium but to its highly hydrophobic nature it can easily pass through the plasma membrane as compared with the magnesium. The oxygen diffuses out faster than magnesium.

Thus, the answer is false.
