The difference between simple diffusion and facilitated diffusion is that facilitated diffusion

Chemistry
1 answer:
Sholpan [36]3 years ago
6 0

Answer:

Simple and facilitated diffusion are both similar types of phenomenon where the substances are moved from a region of high concentration to lower concentration across a semi-permeable membrane.

The main difference between them is that the facilitated diffusion requires a special type of protein or carrier molecules in order to transport the substances whereas simple diffusion does not require such molecules. The rate of flow of these substances is high in the facilitated diffusion in comparison to the simple diffusion.

The carbon atoms in graphite and the carbon atoms in Diamond have different
Stolb23 [73]
It's the actual structure of diamond which made the two different. Diamonds have a tetrahedral structure, and as for graphite, it's not structured in that way. The structures of the two is also the reason why diamond is harder than graphite.

The polymerization of amino acids produces:
Delicious77 [7]

Answer:

Proteins

Explanation:

Polymerization, in chemistry, is the chemical combination of monomeric units to form a polymer. Polymers are large molecules made up of smaller units called monomers. Amino acids are the monomeric units of proteins i.e. A protein is made up of of many amino acids joined together.

Therefore, the chemical combination of amino acids will form a peptide bond between the carbon atom of the acid group and nitrogen atom of the amine group in the structure of the amino acids. This is done by the loss of a water molecule. The continuous repetition of this polymerization process will form a chain called polypeptide, which is the PROTEIN.

A loaded coal wagon with a total mass of 20 000 kg is pushed by a force of 300 000 N. What was the wagon’s acceleration?
AlexFokin [52]

Answer:

<h2>15 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{300000}{20000}  =  \frac{30}{2}  \\

We have the final answer as

<h3>15 m/s²</h3>

Hope this helps you
