Answer: The least reactive non-metal is Selenium.

Explanation:

Chemical reactivity is defined as the tendency of an element to loose of gain electrons.

Non-metals are the elements which gains electrons and hence, their chemical reactivity will be the tendency to loose electrons.

Their chemical reactivity decreases as we move from top to bottom in a group. As, the electrons get added up in the new shell. So, the the electron in the outermost orbital gets far away from the nucleus. And hence, the electron will be difficult to gain.

Their chemical reactivity increases as we move from left to right in a period because the valence shell come closer to nucleus as we move from left to right. So, addition of new electron in the valence shell becomes easier due to greater attraction between nucleus and valence electron.

For the given options:

Option A: Sulfur

Sulfur (S) is located in period 3 and group 16 of the periodic table.

Option B: Chlorine

Chlorine (Cl) is located in period 3 and group 17 of the periodic table.

Option C: Bromine

Bromine (Br) is located in period 4 and group 17 of the periodic table.

Option D: Selenium

Selenium (Se) is located in period 4 and group 16 of the periodic table.

Hence, the least reactive non-metal is Selenium.

The behavioral genetics approach __________. examines the direct influence of genes by studying behavior at the cellular leveL c

natali 33 [55]

Answer:

relies on the evaluation of dreams and the unconscious desires.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

This ultimately implies that, the manner in which living organism such as humans look and behave is largely dependent on both the traits inherited from their parents and the environment in which they grew up or stayed.

Hence, the behavioral genetics approach relies on the evaluation of dreams, unconscious desires, twin, family, and adoption studies which are used to investigate the gene possessed by living organisms or their environment interactions.
