Question

question 18

the following statements of polymers are true:
(choose all that apply)

some can be found inside the body.
some can be melted and reformed.
they are made from increasing the pressure on certain liquids.
they are made of monomers.
they are made from ivory husks

question 19

cesar arcasi-matta says more and more fields are becoming \interdisciplinary.\ what does interdisciplinary mean?

fields that rely on more than one field (for example biochemistry which draws from biology and chemistry).
organizations that train their own employees, so they can change fields of study along the way.
fields that are very specific and specialized, for example quantum chemists.
organizations that hire specialists in different fields to solve problems together.

Explanation:

Analyze polymer statements

We evaluate each statement regarding polymers:

• "Some can be found inside the body": True. Natural polymers like proteins, DNA, and glycogen are essential components of living organisms.
• "Some can be melted and reformed": True. Thermoplastics are polymers that can be repeatedly melted and reshaped.
• "They are made from increasing the pressure on certain liquids": False. While pressure can influence polymerization reactions, this is not a defining general method of making polymers.
• "They are made of monomers": True. By definition, polymers are large molecules composed of repeating structural units called monomers.
• "They are made from ivory husks": False. Ivory is a natural material (mostly dentin), not a source material for polymers.

Define interdisciplinary fields

Using the Interdisciplinary Fields knowledge point

• Interdisciplinary fields are areas of study that integrate perspectives, methodologies, and tools from more than one traditional academic discipline to solve complex problems or explore new areas of research.
• The first option, "Fields that rely on more than one field (for example Biochemistry which draws from Biology and Chemistry)", directly and accurately defines this concept.
