How many molecules of water are released during the polymerization of a 20 monomer long cellulose molecule

Biology
2 answers:
Karolina [17]3 years ago
7 0

Answer: 19 water molecules

Explanation:

Polymerization can be defined as the process by which monomers gets attached to one another to form a polymer. Example: ethene polymerize to form polyethylene.

Polymerization of 20 monomers of cellulose molecules releases 19 molecules of water.

Polymer bond is formed when -OH  group from the first monomers is attached to the H molecules of the second monomers.

For, 20 monomers there will be 19 water molecules released.

29. What conditions would cause a molecule to diffuse from the outside of the structure shown to the inside?
dmitriy555 [2]

Answer:

The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.

Explanation:

The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.

<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated .

The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.

Identify the rectangular solid that represents the cell with the smallest amount of plasma membrane per volume of cytoplasm
Xelga [282]

Answer:

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

<em>Note: The question is incomplete. The attachment below gives the complete question</em>

Explanation:

The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.

The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.

From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:

Solid 1: 10/2 = 5 cm⁻¹

Solid 2: 12.18/2 = 6.09 cm⁻¹

Solid 3: 19.0/2 = 9.5 cm⁻¹

Solid 4: 34.24/2 = 17.12 cm⁻¹

Solid 5: 65.79/2 = 32.895 cm⁻¹

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

Volgvan

Answer: :Total distance to be travelled = 4.4 km

= 4400 m

Diameter of wheel = 70 cm = 0.7 m

Radius of wheel= 0.7 / 2 m

Circumference of wheel = 2 * pi *r

= 2* 22*0.7 / 7* 2

= 22*0.1

= 2.2 m

No. Of revolutions = Total distance / Circumference of wheel

= 4400 / 2.2

= 2000
