The correct answer is B. Cells divide, producing more cells.
Explanation
The cell is the basic unit of life for all living things. Likewise, it is a form of classification for them since living organisms can be classified according to the number of cells they have unicellular (a single cell), multicellular (more than one cell). In organisms that have more than one cell, they divide to produce more cells and form the organs and tissues themselves. Cell division can occur from two processes that are mitosis and meiosis in which two and four cells are produced respectively. According to the above, the correct answer is B. Cells divide and producing more cells.

Answer:
The correct answer is A. Country X has the higher natural increase rate.
Explanation:
Natural increase rate is the excess of fertility over mortality, that is, the difference between the number of births and deaths over a period of time; making the basis for population growth.
As Country X has a crude birth rate of 40 and a crude death rate of 15, its population's natural increase rate is 25. In turn, Country Y has a crude birth rate of 20 and a crude death rate of 9, so its population's natural increase rate is 11. So, as we can see, Country X has a higher natural increase rate.
