A cell is the answer I guess
A = (v2-v1) / t --> t = (v2-v1)/A
t = (55 km/hr)/(2.5 km/hr•sec)
t = 22 sec
Answer:
C, birthrate exceeds death rate
Explanation:
If emigration were to exceed the birthrate, the population would decrease due to so many people leaving and with the birth rate getting lower due to so.
If the death rate exceeded the birthrate, people would be dying all over and no babies would go "goo goo ga ga" because they're probably dead.
If death rate exceeded the immigration rate, then people would just be coming to a country just to die. Like, who would want that?
So yeah, it's C.
