Jack took a pill that increases his sympathetic nervous system arousal. According to Schachter and Singer's theory, putting him in an emotional situation and telling him that the pill will have no effect, would increase the chance of experiencing a strong emotion by him.

The two-factor theory of emotion was given by Stanley Schachter and Jerome E. Singer. According to Schachter and Singer's theory, an emotion is built on two factors i.e. physiological arousal as well as cognitive label.

The theory suggests that when an emotion is perceived, a physiological arousal takes place and the person makes use of the existing surroundings to look for emotional signals to tag the physiological arousal through cognition.

Ksivusya [100]

A substance floats if it is less dense, or has less mass per unit volume, than other components in a mixture. For example, if you toss a handful of rocks into a bucket of water, the rocks, which are dense compared to the water, will sink. The water, which is less dense than the rocks, will float. Basically, the rocks push the water out of the way or displace it. For an object to be able to float, it has to displace a weight of fluid equal to its own weight.

Water reaches its maximum density at 4 C (40 F). As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding.

In which way does the composition of soil, an abiotic factor, rely on living things?
Ivenika [448]

Answer:

Soil Layers. Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories.
