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.

Part II: For each of the genotypes below, determine what phenotypes would
Troyanec [42]

Answer:

4. Brown

5. Brown

6. Blue

7. Long

8. Long

9. Short

Explanation:

Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.

Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.

Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.

For recessive long tails, tt gives short tails, TT and Tt gibe long tails

Why is it important to study grouse habitat selection and demography relative to human land use practices?
nadya68 [22]
Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.
