Function of diastema in herbivores

Gnawing and chewing of plants.

Explanation:

Diastema are spaces found in the dentition of most mammals or any organism that has teeth. It is a space separating dentition for different functions, specially that amongst the biting tooth and grinding tooth. Rabbits are been used  as a case study because they are herbivores and also don't have canines, so the diastema helps with gnawing and chewing of plants.

It is well known according to study that a great number of herbivores have no canine, so the diastema aids in holding, gnawing and chewing of plants. This is really helpful, considering rabbits are herbivores.

And if more:Between DNA and RNA, there are three major differences: 1. DNA contains deoxyribose sugar, RNA - ribose, which has an additional, compared deoxyribose with hydroxyl group. This increases the possibility of hydrolysis of the group of the molecule, i.e. reduces the stability of an RNA molecule. 2. The nucleotide complementary to adenine, thymine in RNA does not, as in DNA and uracil - thymine unmethylated form. 3. DNA exists as a double helix consisting of two separate molecules. RNA molecule, on average, shorter and more preferably single-stranded.   based on this, select the answer yourself)!
