Antagonsitic effect/interaction/response
In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest. 
First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.
The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect. 
Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics. 
        
             
        
        
        
- The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
- Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
- A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
- Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
- Active transportation comes in two flavors:
- Primary active transport
- Secondary active transport.

<span>Hyracotherium, Mesohippus, Merychippus, Pliohippus, because over time, the number of toes decreased and body size increased is the right answer</span>
        
                    
             
        
        
        
Answer:
1. Pigs, Sheep, Goats, Cattle
2. The purpose of rearing pigs is to utilize them for human food but also supply skin, fat and other materials for use as clothing or leather, ingredients for processed foods, cosmetics, and medical use.
3. <em>Breeding</em> - when animals mate and then produce offspring.
<em>Species</em> - Organisms that have lots of characteristics in common, and can mate to produce fertile offspring.
<em>Herd</em> - a social group of certain animals of the same species, either wild or domestic.
Explanation:
4. Bovine - Cattle, Goats, Pigs
    Ovine - Sheep
    Equine - Horses and other members of the horse family
