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 Mnemonics

Mnemonic techniques are personal strategies used to remember information. They act as a “shortcut” that allows us to associate something concrete with what we want to remember.

Attention is one of the main components of memory. In order for information to move from short-term memory to long-term memory, it is necessary to focus attention on that information. When studying or trying to memorize something, it is important to be in a place without distractions and that allows us to focus attention. Thus, the stimulus that matters is highlighted and memorization is facilitated
