A plants cell wall is made of cellulose, this is chains of beta glucose molecules joined together to form fibrals which then join to form cellulose fibres. It on its own is not living but it provides a vital part of the cell so when together with the rest of the cell, the cell is alive.
The answer is option D. We have no way of knowing the number of revolutions of the planets.
Answer:
Option-C
Explanation:
The M phase of the cell cycle proceeds in the four phases: prophase followed by metaphase then anaphase, and telophase.
These sub-phases can be easily distinguished as the genetic material move in the cell in various form and the changes become characteristic of the subphases.
During metaphase, the chromosomes are aligned at the center of the cell or at the imaginary equatorial plate. Since it is mentioned that the drug shows its effect when the chromosomes are aligned at the equatorial plate therefore he is referring to the metaphase of the cycle.
Thus, metaphase is correct.
