Answer:
Data Scientist
Explanation:
Data Scientist (different from a statistician) is a type of researcher that uses computer softwares to analyse and make sense of raw digital data.
Data Scientists usually combine knowledge of computer science, statistics and mathematics while using various softwares to extract information and meaningful, key insights (whether structured or unstructured) from data.
There are two popular types of data scientists: Operational Data Scientists (experts in software implementations and day to day running of the data science wing of a firm) and Exploratory Data Scientists (The real digital data miners, the researchers).
With the way the world is set up now that data is everything, data scientists are a must for every firm as the raw data every firm collects is processed by data scientists.
Answer:
Nature versus nurture is a long-standing debate in biology about the balance between two competing factors which determine fate: environment and genetics. The alliterative expression "nature and nurture"
Scientific investigation is the process in which scientist solve the problems by using different systematic approach. It can be initiated in different ways.
Experimental Scientific investigation: The investigation in which scientist answer the question on the basis of experimental results. Experimental investigation contains both dependent and independent variables, and only one variable is tested at a time is possible. This process makes uses of collecting observation and identifying the process in physical word.
Noting the colour of a solution when heated is the experimental scientific investigation
Therefore, other given options are part of scientific observation whereas Noting the colour of a solution when heated explains the experimental scientific investigation.
A. Chemistry
The scientific study of matter and the changes it undergoes is called chemistry
