In a dna molecule the ratio of adenine (a) molecule to thymine (t) is 1: 1. if in a strand of dna there are 1 million a molecules, how many t molecules are expected in the same strand? a)1 millionb)2 millionc)3 milliond)4 million

Since the ratio of A:T is 1:1, for every A, there is a T. 1 million T molecules are expected.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
