Simple Diffusion Across the Cell (Plasma) Membrane. The structure of the lipid bi-layer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.

Answer:
1. 1.26823082 mL
2. 0.5 g/mL
Explanation:
The density formula is:
1.
Rearrange the density formula for v,
<em>Multiply both sides by v.</em>
<em>Divide both sides by d.</em>
Volume is found by dividing mass by density. The mass is 20 grams and the density is 15.77 grams per milliliter.
Substitute the values into the formula.
Divide. Note the grams, g, will cancel.
2.
Use the density formula.
Density is found by dividing mass by volume. The mass is 10 grams and the volume is 20 milliliters.
Substitute the values into the formula.
Divide.

Answer:
Re-replication is allowed on geminin depleted cells
Explanation:
The depletion of the geminin gene by the siRNA leads to re-replication of portions of the genome. This is due to the protein Geminin be responsible to inhibit the replication factor cdt1 and therefore one replication round is allowed in wild type cells at the S phase. Therefore, Geminin-depleted cells will re-replicate their genome causing the enlargement of the nucleus.
