d) independent that's the answer
This arrest of division is an example of Density-dependent inhibition. Density dependent inhibition is the process where crowded cells stop dividing; the number of cells in an area force competition for nutrients, space, and growth factors, therefore, when cells are crowded, they get signals to stop dividing. In density dependent inhibition, when density is high there is no cell division and when the density is low cells divide.
Solution:
A train travels at 69 kilometers in 1 hours and then travels 98 kilometers in 5 hours.
(i)Total distance traveled = 69 + 98
= 167 kilometers
(ii) Total time taken to cover total distance = 5 + 1
= 6 hours
(iii) Average speed = total distance traveled divided by total time taken
= 167/ 6 = 27.83 kilometers per hour
