How students are disscussing natural selection in bacteria

Biology

Elis [28]3 years ago

Antibiotics are, initially, molecules naturally synthesized by microorganisms to fight against bacteria competing with their environment. This created a pressure of selection on the bacterial populations, leading to the appearance of resistant strains. In fact, when an antibiotic is used, only bacteria with defense systems against this molecule survive (and reproduce).

nikdorinn [45]

Answer:

1 or 100%

Assuming that the allele B (brown) is dominant over the allele b, crossing the father and the mother:

          BB    x    bb

      Bb    Bb    Bb    Bb (you can also see the Punnet's square)

Kruka [31]
The answer is 12.5%.
Each gram of protein has four calories. Therefore, 50 grams of protein contain 200 calories. In order to find the percentage of total energy intake that comes from protein, we need to do the division: 200/1600 * 100 = 12.5. Protein is needed for body growth and maintenance and energy.
