The correct binomial nomenclature for humans is H. sapiens, in which H. is genus and sapiens is species.
<h3>What is binomial nomenclature?</h3>
The binomial nomenclature is a two-term naming system in which the name of every species is named specifically.
This naming system was developed by Carolus Linnaeus.
It is written as a genus with the following species.
For example the scientific name of the dog is Canis (genus) familiaris (species).
Thus, the scientific name of humans is H. sapiens.

The main concept of cell theory is that cells are the basic structural unit for all organisms. ... Living things may be single-celled or they may be very complex such as a human being. ... Cells hold a variety of pieces and each cell type has a different purpose. ... The trillions of cells in your body make your way of life possible.
Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
Being genetically identical to the parent is advantageous for organisms when the environment changes fast, and reproduction is needed.
A gamete (a reproductive cell with one set of chromosomes, like an egg or sperm) combines with another to form a zygote, eventually developing into an organism of cells with two sets of chromosomes. Sexual reproduction is a type of reproduction that involves this complex life cycle (diploid).
The advantages of sexual reproduction are numerous. Several instances include:
more genetic variation
immunity against contagious diseases
fewer genetic diseases
Evolutionary fitness has increased
