Answer:
-Option (d).
Explanation:
BFB (breakage-fusion-bridge) cycle can be defined as a mechanism associated with chromosomal disabilities. The breakage-fusion-bridge cycles are associated with tumorigenesis as it induces chromosomal abnormalities in cells.
It starts with breakdown of chromosomal end region (telomere). When that chromosome goes for replication, daughter chromatids formed by it lack telomere.
During anaphase, fused chromosomes get separated and each daughter cell gets a chromosome without telomere. These mutated daughter cells replicate again and as this process rerun, it can lead to accumulation of chromosomal instability and tumor formation.
Thus, the correct answer is option (D).

Answer:
it helps the process go much faster and more efficient
Explanation:
Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.
Explanation:
Density dependent factors are the aspects of the environment that limit a population's growth regardless of the density of the population. So in this case, the answer is hurricanes.
