The correct answer is d. "Regeneration" means "forming new cells," and signifies that the disease-causing bacteria cells are multiplying. When there are more of these cells, there is a higher chance for antibiotic resistance (making it take longer for the antibiotics to work). Once there is a smaller concentration of these bacterial cells, the antibiotics become more effective.

Answer:

The correct answer will be option-B

Explanation:

Antibiotic is the antimicrobial substance which inhibits the growth of the bacteria by interfering with different process and destroying the cell wall.

If the same antibiotic is used for the same colony of bacteria then bacteria can respond by becoming resistance to the antibiotic and as a result of this, the antibiotic becomes ineffective for the bacteria.

Since bacteria live for only a few days, therefore, the disease-causing bacteria dies off after a few days. The antibiotic then acts on the susceptible bacteria and kill the bacteria.

Thus, Option-B is the correct answer.

6. Think and discuss: Did the changes you observed in the moth populations result from
irina [24]

Answer:

The changes I observed in the moth populations result from the best-hidden moths surviving and reproducing, passing on their colors to their offspring. Why? Because individuals NEVER evolve, populations do. The second option fits best with Darwin's theory of natural selection, in which he stated that individuals with the most favorable traits are the ones to survive and reproduce, thus passing their traits onto the future population. The first choice incorrectly believes in Lamarck's theory of evolution in which he incorrectly believed that individual organisms in the population developed a trait that would help them survive (e.g. longer necks in giraffes).

The light-independent reactions of photosynthesis need
Advocard [28]

Light-independent  reactions are the second stage of photosynthesis. They make sugars. Light-independent takes place in the stroma and doesn't require light. They need carbon dioxide (CO2) from the atmosphere to build the sugars. These sugars are used to build starches and cellulose in a cycle of chemical reactions.

The reported mass will be too high because the initially recorded mass will include both water and impurities and the final mass will without both components. The difference will be larger so the amount of water reported would be higher.
