Answer:

E

Explanation:

A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.

<em>Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.</em>

<u>These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.</u>

In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.

Sodium (Na) ____<br> atomic # 11<br> atomic mass: 23
SVETLANKA909090 [29]

Find # of electrons and draw them onto the Bohr model.

Assuming the atom has a neutral charge, the number of electrons equals the number of protons.  The number of protons is given by the atomic number, 11, so there are eleven electrons.

From the inner "ring" to the outer "ring":

1.  The first "ring", closest to the center of the atom, can take two electrons.

2.  The second "ring", level 2, can take the next six electrons.

3.  The rest of the electrons (three) can fit on the outermost ring.
