The correct answer is option D
The population of rabbit over the first unit of time is reduced because the population of snakes was more than the normal population.
The predators of rabbits are snakes and if the population of predator will be more than the population of the rabbit then snakes will eat them. Ultimately the population of rabbit will be decreased.
Then after some time the population of rabbit increased as the population of snakes decreased.
Data given
Number of electron = 108
Number of neutron = 158
Required
Mass number=?
Solution
As we know that mass number = No of proton + No of neutron
In any neutral atom the number of proton is always equal to number of electron
So number of proton will be = 108
However the atom has +1 charge which means that one proton is less than no of electron so proton number is 107.
Put values in above formula, we will get
Mass number= 107+108
= 215 Mass number
