The sea slug Aplysia will withdraw its gills if it is squirted with water. If the squirts continue, as they do in nature, the withdrawal response will diminish. But if the sea slug receives an electric shock after being squirted, the withdrawal of the gills will grow stronger. This is an example of

When the sea slug Aplysia withdraw its gills if it is squirted with water. If the squirts continue, as they do in nature, the withdrawal response will diminish. But if the sea slug receives an electric shock after being squirted, the withdrawal of the gills will grow stronger.

It shows an example of Assciative learning.

Explanation:

Associative learning is a type o learning in which the individual establishes a link between two different experiences to reinforce them as well as to increase the meaning of the experiences. In our case, the association will come because the electric impulse is going to be released after it is squirted with water and later it will associate that after a squirt of water an electric pulse will arrive.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
