Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

It is associated with more or less why a genetic counselor would need to look at distinct human populations, with which an individual is related to when doing certain kinds of tests. For instance, if someone knows about their ancestry then the counselor would be able to tell about the genetic disorders most commonly occurring in that particular ancestry.
The basic way of seeing at it from a population genetics point of view is how populations do differ genetically and how does it associate with the probabilities of exhibiting a mutation in the person.
Answer:The scientific method is practiced within a context of scientific thinking, and scientific (and critical) thinking is based on three things: using empirical evidence (empiricism), practicing logical reasonsing (rationalism), and possessing a skeptical attitude (skepticism) about presumed knowledge that leads to self.
Gene expression involves formation of various proteins from specific genes. The expression starts with the process of transcription where DNA is transcribed into a mRNA by enzyme RNA polymerase. Then mRNA diffuses out of the nucleus and the process of translation takes place in the ribosomes generating a polypeptide then a protein is formed. Therefore, the correct answer is transferring of information from DNA to messenger RNA (transcription).
