Volume of alcohol = 4 mL of alcohol

Volume of water required = 194 mL

<h3>What is a dilution factor?</h3>

A dilution factor is a ratio of the solute to solvent. It is used to express how much of the original stock solution is present in the total solution.

Given the following dilution to make:

obtain 200 ml of an isopropyl solution using the dilution ratio 1 : 20 of alcohol to water.

Total volume = 200 ml

Volume ratio of alcohol to solution will be 1/50 * 200

Volume of alcohol = 4 mL of alcohol

Then volume of water required = 200 m - 4 ml

volume of water required = 194 mL

In conclusion, the dilution is done using the dilution factor.

Answer:

68 1/2 foot length

Or 22 5/6 yards.

Explanation:

The yard length of the part of the goal post

The base (10 foot)

The crossbar (18 1/2 )

And two arms (20 foot each)

Let's sum up the total yards

=(10 + 18 1/2 + 20 +20) foot

= 68 1/2 foot length

Or 22 5/6 yards.

Cells can make proteins that need to be transported out of the cell and moved to another part of the body. Cells also make carbo

alex41 [277]

Answer:

The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.

Explanation:

Diffusion is the passive transport of substances down their concentration gradient. The process moves the substances from the region of higher concentration to that of lower concentration. CO2 is a small molecule and does not have any charge. Small, uncharged molecules can diffuse through the lipid bilayer of the cell membrane. Therefore, CO2 can exit a cell by simple diffusion.

On the other hand, proteins are too large to be transported by diffusion across the cell membrane. The proteins are transported by exocytosis. During exocytosis of proteins, membrane-bound vesicles are formed inside the cell. These vesicles carry proteins in them and are called secretory vesicles. The membrane of the vesicles fuse with the cell membrane of cells and transport the proteins outside the cell.
