During both meiosis I and meiosis II, cells<span> undergo the same phases found in mitosis, but the processes and results are different. Within meiosis I, homologous chromosomes become paired and crossing over occurs. Homologous pairs are separated, and the two resulting </span>daughter cells<span> have half as many chromosomes per </span>cell<span>.</span>

Explanation:
The missing options of this question are:
I only
II only
III only
I, II, and III
The correct answer is "I, II, and III".
Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:
I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.
II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.
III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.
Answer:
Temperature will increase
Explanation:
As we know
Where KE represents the Kinetic Energy, R represents the gas constant and T represents the temperature.
As the kinetic energy increases, the velocity of the gas molecules increases due to which the gas molecule start moving rapidly and hence exerts higher amount of force on the wall of the container in which it is kept.
The higher force leads to generation of higher pressure and hence the higher temperature.
