Time on earth is divided into 6 eras. Three are considered "Precambrian" Which eras are NOT Precambrian?
bulgar [2K]

Explanation:

<u>the  Paleozoic Era </u>

The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.

Just before the Cambrian eruption, in the  Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

Some proteins catalyze biochemical reactions. If a genetic defect prevented a protein catalyst from being produced which of the
Maslowich
I believe option B would be the correct choice because, without a catalyst, the reaction will be either too slow or will not happen at all as it would not acquire a fitting activation energy for the reaction. 
If you would like to know why the other options are incorrect, please read on: 
Option A is incorrect because since proteins are specific in nature, so other protein cannot be replaced, for some other chemical reaction. 
Option C is not correct it is a genetic defect that the protein does not form, and all cells are genetically identical, a reaction cannot take place in any parts of the body. 
And finally, option D would be wrong because if a forward reaction does not take place, a backwards reaction will not occur. 
I hope this answer has helped, and I apologise if somehow this answer finds itself to be incorrect. Good luck on your quiz or homework. :)
