Answer:

The gravel of the sand will dissolve a part and what is not dissolved will be deposited on the bottom of the Beaker. The gravel deposited on the bottom of the Beaker will change color, presenting a darker color than normal.

Drops of sunflower seed oil, on the other hand, will accumulate in several circles, will not dissolve and will float on the water surface inside the Beaker.

Explanation:

Gravel of the sand is a polar material, which means that it mixes with the water dissolving in it. However, the payment contained in a beaker has a dissolution limit, in which case when the gravel of the sand is poured into a beaker with water, the gravel will be dissolved until it reaches the dissolution limit. When this limit is reached, the gravel of the sand that has not been dissolved will be deposited in the bottom of the beaker. The color of the gravel of the sand will also change, becoming darker.

Drops of sunflower oil are nonpolar substances, which means that they will not be dissolved in water. However, these drops will come together in several circles and will not mix in the water, but will remain floating on its surface.

Sunflower oil is less dense than water and therefore remains on the surface, while gravel of the sand is more dense than water and is therefore deposited on the bottom of the baeaker.

Nikitich [7]

The correct answer would be, the social construction of mental illness.

They were also thought more likely to give birth to children who were also Feebleminded. Today this attitude seems ridiculous. This is an example of the social construction of mental illness.

Explanation:

Feebleminded people are the people who are unable to make wise and timely decision about any situation. They are mentally unstable and ill. They are generally called foolish or half baked people.

In the early twentieth century, women who were feebleminded were thought to give birth to the children who will also be feebleminded, but with the passage of time, mental illness has been accepted socially by people and they have understood a lot that it is not necessary that feebleminded women reproduce feebleminded offspring. This is called the social construction of mental illness.

Which of the following is true of divided attention in the context of memory encoding?
Talja [164]

The process of encoding information in the proper context for memory encoding can be particularly harmed by divided attention.

Because attention is essential for encoding and developing the semantic characteristics of a stimulus, which similarly improves both types of memory, it is believed that division of attention reduces conceptual priming and explicit memory.

What is context of memory encoding?

  • Information can be encoded, stored, and recalled through memory. An organism may learn from its past experiences, adapt, and form relationships thanks to memories.
  • A perceived useful or interesting object can be transformed into a construct by encoding so that it can be stored in the brain and later retrieved from long-term memory. Hooking onto previously archived objects already present in a person's long-term memory helps working memory store information for immediate use or manipulation.
  • Although encoding is still a relatively new and undeveloped field, its roots can be seen in the works of ancient philosophers like Aristotle and Plato. Hermann Ebbinghaus is a key player in the history of encoding (1850–1909). Ebbinghaus made significant contributions to memory study.
  • He used himself as a subject to study how people learn and forget knowledge by repeatedly saying a list of random sounds to the beat of a metronome until he could recall them.  As a result of these trials, he proposed the learning curve.
