If scientists wanted to learn more about evolutionary history, they would study all but one of these molecules. which biological molecule would not offer much information about the history of life? a) dna b) proteins c) nucleic acids d) phospholipids

D. Phospholipids

Explanation:

To trace back the evolutionary history of the organisms nucleic acids such as DNA, RNA and proteins are taken into consideration and these molecules have been proved to indicate the origin of new organisms from their common ancestors. But phospholipids cannot be considered because of the fact that it is found in the cell membrane composition and this is not a material of inheritance that is it is not passed on from the parents to their offsprings by the process of reproduction.  

answer; polycythemia is the correct answer;

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
