<h2>Answer</h2>
By the attraction between atomic particles of opposite charge
<u>Explanation</u>
An ionic bond is created by the attraction between atomic particles of opposite charge because when the charges are unlike they attract and in this type of attraction there is a complete transfer of charges. In the ionic bond complete transfer of charges takes place. Ionic bonds are formed between elements which have electronegativity changes greater than 1.4 or less than that. It is formed by a combination of cation and anion.
In the society of clones, human clone lacks traits necessary for true independence from "parent" cells.
<u>Explanation:</u>
Clone can be defined as an individual organism that was grown from a single body cell of it's parents and that clone is literally identical to it's parent from which it has grown.
In this society, a human clone lacks traits necessary for true independence from the "parent" cells. There is also a contrast that whether a clone is entitled by contrast to feel that a parent cell is an appropriate parent cell or not.
I think the answer might be D
(16.5 m/s + 5 m/s) ÷ (40 m) = 0.5375 Hz
1 ÷ 0.5375 Hz = 1.86 s
round up and you get 1.9 s, so the answer would be A.
