by experimenting the layers of the earth
Answer:
The correct answer will be options-
1. they share genetic similarities
2. they can interbreed
3. they fall under the same genus
Explanation:
The taxonomic studies help the organism to identify, nomenclature and classification of the organism.
The classification system helps organize the organisms into several groups based on the similarity of the morphological characters. The species is the lowest group of the system which contains the organism which is reproductively isolated from the other group of organism.
If two organism is found to be of the same species shows that they share the same gene pool, belongs to the same genus and they can interbreed.
Thus, the selected options are the correct answer.
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 × 2 = 46).

Answer:
Chitin, Cellulose and Peptidoglycan (B, C and D)
Explanation:
Both chitin and cellulose are composed mainly of glucides, bound by glycosidic bonds of the Beta 1-4 type. This is largely why they cannot be digested by most non-herbivorous animals.
As for peptidoglycans, it is a net. It is a molecular framework present in bacteria that has β1-4 and α1-4 bonds in different proportions.
