A Mineral is any occurring, inorganic, crystalline substance ( normally an element or a compound) that possesses a fairly definite chemical composition and a distinctive set of physical properties. They are formed naturally in the Earth, they are usually solid, inorganic, have a crystal structure, and form naturally by geological processes.

The molecules of a substance must have what characteristics in order to be flexible

Goryan [66]

Answer:
The molecules of a substance which must have the ability to move past one another are said to be flexible.

Explanation:
Those substances are said to be flexible which can be bent without breaking. There are many substances which are hard in nature but still can be bent. The hardness of such materials is due to strong interactions between the molecules and the flexibility comes due to their amorphous backbone. Therefore, greater the crystalline level of macromolecules lesser is the flexibility and greater the amorphous character greater is the flexibility and vice versa. Also, the flexibility of polymers is increased by adding plastisizers in it. Plastisizers make the hard polymers flexible by breaking the crosslinkers and enabling the macromolecules to move past one another.

When cyclohexene is treated with KMnO4, H2O, the syn-1,2-diol is produced. What reaction occurs when benzene is similarly treate

Ulleksa [173]

Answer:

No reaction is observed

Explanation:

The benzene ring is aromatic. Being an aromatic ring, the benzene ring is remarkably stable to all reactions that destroy the aromatic ring.

Alkenes are oxidized to alkanols in the presence of KMnO4 but this reaction does not occur with benzene. However, substituted benzenes having hydrogen atoms attached to the substituent carbon atom can be oxidized to the corresponding carboxylic acid.

Answer:

Error or mistakes during DNA replication is accountable for two-thirds or 66% of the cancer cases. These random and unpredictable errors called mutations that occur during the division of a cell as an error in copying of DNA.

DNA replication has three main steps:

Opening and separation of DNA strands of a helix - carried by an enzyme known as helicase that breaks the hydrogen bonds between nitrogenous bases of the helix of DNA.

The priming of the template strand - DNA primase helps RNA primers to bind to both strands at 3' end as soon as it separated

strat assembling the segments of new DNA on strands called elongation of the strands with help DNA polymerase I and after forming new strands the termination of the replication.

Errors or mistakes can occasionally take place if DNA polymerase inserts a wrong base during elongation of the strands.

It is endothermic reaction ΔH>0 (sign is +).
Because it is spontaneous reaction ΔG<0 (Gibbs free energy)
ΔG=ΔH-TΔS, so must be TΔS>ΔH and ΔS>0 (sign +).
