Transformation is the genetic alteration of a cell resulting from the direct uptake of incorporation of exogenous genetic material from its surrounding through the cell membrane.
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.
Answer: air mass
Explanation: An air mass is a large body of air with generally uniform temperature and humidity. The area over which an air mass originates is what provides its characteristics. As such, air masses are associated with high pressure systems.
