Different codes for access code which are available are: 4000
_ _ _ _
1 2 3 4
1st blank can be filled with the following possibilities, here the conditions are:
1)The first digit cannot be 4
2)The first digit cannot be 0 also since it makes the access code 3 digits hence
From 1 to 9 except 4 there are 8 possible ways to fill that blank
<u>8</u>
2nd blank can be filled with any number between 0 to 9 in 10 possible ways
<u>8</u> <u>10 </u>
3rd blank can be filled with any number between 0 to 9 in 10 possible ways
<u>8</u> <u>10</u> <u>10</u>
4th blank can be filled with any odd numbers between 0 to 10 - 1,3,5,7,9
<u>8</u> <u>10</u> <u>10</u> <u>5</u> = 8 x 10 x 10 x 5 = 4000
Hence to conclude that 4000 available codes are there for the access security card

During osmosis, a statement which correctly describes the movement of water across a selectively permeable membrane is: 3. Either of these descriptions is correct and equivalent.
<h3>What is osmosis?</h3>
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a selectively or permeable membrane from a region of high concentration to a region of lower concentration.
This ultimately implies that, the process of osmosis can be illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.
In conclusion, the movement of water of from high water concentration to low water concentration and from low solute concentration to high solute concentration are statements which correctly describes the movement of water across a selectively permeable membrane during osmosis.
