Most likely an altimeter,
microscopes can be too heavy to carry outside,
x-ray diffraction is used to determine the molecular structure of a crystal so that is not likely to be helpful,
but an altimeter determines the altitude of an object on a fixed level, so that can be useful during a field investigation
hydrometers-measure gravity of liquids, probably not useful for a field investigation
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The birth of modern science (c.1500-1700) was important to how we understand the knowledge and disciplinary divisions today because the scientific method was established to get proper validation to the things in nature that in the past were attributed only to dive concepts expressed by the Church.
That old fashion way of thinking, validated by the church during the dark ages of Medieval Times, only created fear and fostered ignorance in people.
The advent of modern science changed this thing, basing its theories and answers on proper research that could be proven. That is how the human mind expanded and grew. No more myths and distorted religious beliefs that were so wrong.
Biology is the study of life. Humans, Animals, Plants in order to find out the information we know about different species we must study them. 1. It'll inform you about, "Why trees grow..." or "What does...do for you" 2. It's something important to learn.
