please give answer with explanation

Answer 1

Answer:

because bacteria are divided in 1 hours and cup fill up and 60/2=30 bacteria are half filled the cup

Answer 2

Answer:

2] 59 mins

Explanation:

At 59th Min, they were half cup.. in 1min i.e. at 60th min they divided again and doubled i.e. full cup.

Binary fission means one bacteria will divide and form two new bacteria.. (in such cases parent identity is destroyed i.e. nothing is left of original bacterial body after fission)
