Na 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 million

b) 2 million

c) 3 million

d) 4 million

The correct answer to the question above is:

A)   1 million

Since ratio means the quantitative relationship between two values which the frequency of one value is contained within the second value. In this case, it is only 1:1 which means that whatever the number indicated in the first value is equal to the second value. 

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
