This type of rock is made from compacting and cementing.
Sedimentary rock.
A team of biology students conducted an investigation to test how four different solutions affect the volume of a raw chicken egg. Four identical raw chicken eggs were then placed into four individual containers. Each container had a different solution. After 24 hours, the volume of each egg was measured and recorded. What is the test variable (independent variable) in this investigation?
The different types of solutions.
