Which of the following is true about the genetic code?

A. It is universal among all life on Earth.
B. It codes for chains of triglycerides.
C. It is unique to humans.
D. It is universal among animals.

It is universal among all life on Earth  is true about the genetic code.

A genetic code is a set of rules through which the information gets encoded in to the DNA or RNA sequences.The living cells then translates these information into proteins. The genes that acts as codes for proteins are made of tri-nucleotide.

These genetic codes are universal in nature for all the living organisms in the Earth. Only slight difference occurs. This is because one amino acid can be coded by more than one codon. A genetic code is considered to be repetitive in nature. Thus, It is universal among all the life on Earth will be true with the genetic code.

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.
