Artificial Selection is a form of selection in which humans actively choose which traits should be passed onto offspring. Humans have used selective breeding long before Darwin's Postulates and the discovery of genetics. Farmers chose cattle with beneficial traits such as larger size or producing more milk, and made them breed; and although they may have known nothing about genes, they knew that the beneficial traits could be heritable. The farmers selected for certain traits in their cattle and probably noticed that the offspring were becoming more and more productive with each generation. Scientists study these traits and spend a lot of time calculating how heritable these traits can be. The more these traits are expressed in the offspring (i.e. size, milk production, etc), the more heritable these traits are said to be. Hunting is also a form of artificial selection, with the genes that humans "want" (i.e. - the biggest buck with the most points, the largest fish, etc.) being removed from the gene pool, allowing the less "wanted" genes to pass on to the next generation by increasing their odds of mating when compared to the hunted specimens.
Hope this will help.
The cavity which separate or in between the nose and the mouth is the nasal cavity.
The nose and the mouth meet at a junction called the pharnx; option A
<h3>What is nasal cavity?</h3>
The nasal cavity refers to a large, air-filled space above and behind the nose in the middle of the face. It is the cavity which divides the nose and mouth.
However, the nasal septum divides the cavity into two cavities .
- The larynx is the passageway for air between the pharynx above and the trachea below.
- The pharynx carries air, food and fluid down from the nose and mouth.
So therefore, the cavity which separate or in between the nose and the mouth is the nasal cavity.

Answer:
genus, specie
Explanation:
The binomial nomenclature is a naming system used by scientists to identify organisms, it's composed by two words, <em>the first refer's to the individual's genus, a small group of closely related organisms, and the second word is the specific name or epithet used to diffetentiate species in the same genus. </em>
