  1. The answer is the first one: binary fission.
    Explanation: Most bacteria reproduce by binary fission, which is a simple form of asexual reproduction where a single bacterial cell divides into two identical daughter cells. Endospores are a form of survival rather than reproduction, budding is more common in yeast, mitosis is a process of cell division in eukaryotic cells, and sexual reproduction is not typical for bacteria.

  2. The answer is the fourth one: 64.
    Explanation: In binary fission, each generation doubles the number of bacterial cells. Starting from a single bacterium, after six generations, the number of cells is calculated as 2^6 = 64.

  3. The answer is the fourth one: Temperature.
    Explanation: While all the listed factors can influence bacterial growth, temperature is often the most critical factor. It affects the rate of metabolic reactions and enzyme activity, which are crucial for bacterial growth. Each bacterial species has an optimal temperature range for growth, and deviations from this range can significantly slow down or halt growth.
