Answer:

d. a single variable.

Explanation:

<em>A controlled experiment is one in which the researcher can can keep all other factors/variables uniform and see the effects of a particular factor/variable on certain subjects. </em>

For example, in order to determine the effects of different light intensities on the growth of a plant species. All the growth conditions will be uniform for all the subjects (the plant species) except the light intensity. Any discrepancy in growth can thus be attributed to the different light intensities.

The light intensity is varied while other factors are kept uniform.

fredd [130]

Answer:

c. He might have recently had a round of antibiotics that killed the bacteria that usually live in his gut and allowed a yeast species to overgrow. Put him on probiotics and a low carb diet for a week and recheck his blood alcohol.  

Explanation:

This patient may have taken some antibiotics to contain any infection he was having. Antibiotics are medicines with a high power against bacteria. These medications can only be taken with medical supervision because they can kill all bacteria in the body and our gut has beneficial bacteria that help us during digestion.  Probably the antibiotic that the man took killed all the bacteria present in his gut and this allowed for a proliferation of yeast that started an alcoholic fermentation caused the sensation of being alcoholized to the man.

The ideal thing to do with this patient is to prescribe probiotics and put him on a low-carb diet for a week and recheck the blood alcohol.

<h2>Favorable forward reaction </h2>

Explanation:

  • The very favorable forward reaction means that the reverse reaction is very unfavorable
  • This strong forward reaction driving energy effectively inhibits the depolymerization reaction DNAn + pyrophosphate → dNTP + DNAn-1
  • A response that both absorb heat and decreases entropy will be non-unconstrained (positive ∆G) at all temperatures. A few responses, in any case, have a blend of ideal and horrible properties (discharging heat yet diminishing entropy, or retaining heat yet expanding entropy). The ∆G and suddenness of these responses will rely upon the temperature
