Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.

The correct statement is that proteins and carbohydrates have the same amount of energy.
Explanation:
The 90 percent of the dry weight of the diet and 100 percent of its energy is supplied by proteins, carbohydrates, and fats. All these macronutrients provide energy to the body, however, the amount of energy in one gram varies, that is, 9 calories in a gram of fat, and 4 calories in a gram of protein or carbohydrate.
These nutrients also vary in the rate by which they supply energy. Of the nutrients, fats are the slowest and carbohydrates are the quickest.
