Examination of your slide will show that a few nuclei do not appear next to a cell wall

Svetradugi [14.3K]

Hello. This question is incomplete. The full question is:

"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation? "

Answer:

You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.

Explanation:

Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.

If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.

AleksAgata [21]

Answer: 1.B). Evolution genetics.

2.C). Less Bacteria becoming resistant to the specific Antibiotics .

Explanation:

Evolution genetics is field of science, which includes study of genetic variations that lead to evolutionary changes in organisms. As some bacteria had changed their DNA that led to development of antibiotic resistance in them.

Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them

Thus, the correct options to be filled in the blanks are option (B) and option (C).
