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.

How are interphase and mitosis different from one another?
seraphim [82]

Answer:

<em>Hi Todoroki here! UwU</em>

Explanation:

The key difference between interphase and mitosis is that interphase is the longest phase of the cell cycle in which cell grows and replicates its DNA while mitosis is a short phase of the cell cycle in which cell nucleus turns into two nuclei that bear identical genome as the original nucleus to produce two new cells.

Explanation:

Based on the information provided within the question it can be said that the term being described is a multiple cloning site or MCS for short. Like mentioned in the question this refers to a region of DNA located inside a Plasmid, which holds various Restriction enzyme sites clustered in one reagion, each of which are unique.

Nitrogen gas reacts with hydrogen gas to form ammonia What are reactants in this chemical reaction?
krek1111 [17]

1 mol 2 mol  

84g of N2(g) = 84/28 = 3 mol of N2(g)  

From the above reaction 1 mol of N2(g) gives 2 mol 0f NH3(g). So 3 mol of N2(g) should give 6 mol or (6x17) 102 g of NH3(g). But we are getting only 85.0 g of NH3.  

Hence %yield of NH3 = 100x85.0/102 = 83.3%  

Answer D. is correct.  

2. 2HgO (s) --------------------- 2Hg (l) + O2 (g)  

2 mol 2 mol 1 mol  

4 mol 4 mol 2 mol  

As only 1.5 mol of O2 is obtained, so % yield = 1.5x100/2 = 75.0%  

Moreover 603 g of Hg = 603/200.59 = 3.00 molof Hg. Considering this also  

% yield = 3x100/4 = 75%

Explain how the molecular structure of water gives it properties that make it useful to humans
KIM [24]

Answer:

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
