Answer and Explanation:
Sand crabs are known by this name mainly because they spend an important part of their lives buried below the sand. As other crustaceans, they are characterized by the possession of antennae, a structure that has several important roles in their behaviour and physiology.
For instance, they are an important feature in their feeding behaviour. When a sand crab feeds, it begins by showing only its eyes and first pair of antennae. However, as ocean waves recede, they show a second pair of antennae that serves to filter the microcrustaceans and phytoplankton - their main food source. This enables the crab to gather food and survive in this tough environment.

The correct answer is experiment
Experiment is <em>"a type of scientific research in which the researcher manipulates and controls one or more independent variables and observes the variation in dependent variables concurrently with the manipulation of independent variables."
</em>
The purpose of manipulating and measuring the variables in the experiment is to capture causality (relationship between cause and effect). Independent variables are responsible for possible causes, and dependent variables signal the effects. Two variables may have a very high correlation, but not necessarily one cause the other. There are three conditions for admitting causality
