The question is incomplete, the questions asked by the students were as follows:
1. What kind of plant life grows naturally in the town park?
2. Which types of treats do different types of dogs like best?
3. Do different types of grass affect how far a ball rolls?
4. How are the chemicals in different vegetables similar?
The answer is 3
Explanation:
Three types of investigation are used by scientists to solve a problem or answer a question. These questions are: comparative investigation, descriptive investigation and experimental investigation. Experimental investigations are conducted to test the relationship between two variables. In the test, one of the variable is manipulated (independent variable) while the other responds (dependent variable).
In this case involving questions asked for a science fair, HOW DIFFERENT TYPES OF GRASS AFFECT BALL ROLLS is most likely an experimental investigation because it is testing the effects of grass type (independent variable) on ball roll (dependent variable).
Carbon is an integral part of many biological processes. Living things use carbon throughout their system. Plants need carbon to go through photosynthesis. People give off carbon through cellular respiration. Hope this was somewhat helpful
The xylem is the structure of the plant that is
responsible for transporting water from the ground up to the different parts of
the plant. It is composed water, inorganic ions, and a number of organic chemicals.
<span>
Xylem tissue is found throughout the plant
because not only does it transport water, but it also transports the nutrients
that the plant needs for different processes. Aside from being responsible for
the transportation of materials, the xylem is also used to replace water that
was lost during photosynthesis and transpiration. </span>

Answer:
The physical properties of matter can be measured precisely using tools, such as a triple beam balance, a graduated cylinder or beaker, a metric ruler, timing devices, or a thermometer.
