Answers
Selective breeding is a technique to obtain offspring with desired traits, characteristics of cattle include meat and height, whereas wheat is obtained by crossing high yield plants.
What is Selective breeding?Selective breeding is a human technique used to obtain descendence (either plants or animals) from a given genetic cross.
This technique (selective breeding) is used in agriculture to obtain wheat with higher grain yields.
Two characteristics of cattle that have been human-driven selected include meat and average size (height).
It is possible to obtain wheat with desired features by crossing plants having desired genes (it is an autogamous plant).
The characteristics of the chickens (Kendo and Bibby) are not found here, but it is possible to select desired phenotypes by crossing them and selecting offspring.
In conclusion, selective breeding can be used to obtain offspring from a given genetic cross expressing desired traits.

2. describe three situations in which ionic reactions go to completion.
Answers
The three situations in which ionic reactions go to completion is formation of a gas, a precipitate and a slightly ionized product.
What are ionic reactions?It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.
Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.
