Answer:
The change in size of a gummy bear when placed in water is due to the presence of gelatin in the gummy bears.
Explanation:
Most of the gummy candies, like the gummy bears are made up of gelatin. To make the gummy bears, water and gelatin are mixed and heated. Then, this mixture is allowed to cool. During cooling, the water evaporates leaving the gelatin in a chewy form.
When the gummy bear is placed in water, the water is absorbed by the gummy bear due to osmosis. Hence, the gummy bears tend to increase in size.
Water is a hygroscopic substance i.e it tends to absorb water. So, this property of gelatin will enable it to absorb water and increase in size.

Answer:
- force people to flee their homes
- cause massive earthquakes
- pollute the air with volcanic smoke
- make airplanes fly around ash clouds
Explanation:
The volcanoes can be seen as both creative and disruptive force. The disruptive side of the volcanoes includes numerous things. Because of the big pressure that the volcanoes make on the crust, it is very common that they create earthquakes, some being very strong. They release enormous amounts of gases, ash, and pyroclastic material, resulting in pollution of the air. The gases and ash can stay in the atmosphere for longer period of time, as well as travel over long distance, making the airplanes change their routes and go around them, or stop their flights until the air clears out. The volcanic eruptions themselves are very dangerous for the people, be it calm with lava flows, or with explosive eruptions, the people a forced to flee their homes and leave everything behind in order to save their lives.
Answer:
Each three base sequence of the mRNA, called a codon, is read by the ribosome, and the appropriate amino acid is inserted into the growing protein. If you have only a DNA sequence, to find the corresponding amino acids first transcribe your DNA sequence into an RNA sequence using complimentary base pairing.
