Question

Physical or biological?

1) Jacket fiber (100% cotton)
2) Bullet casing
3) Glass fragments
4) Ransom note

Answer 1

The question involves categorizing items as either physical or biological. Jacket fiber made of cotton is biological, while the bullet casing, glass fragments, and ransom note are physical objects.

Step-by-step explanation:

The student's question appears to deal with objects and substances that could be categorized as either physical or biological in nature. To address each item:

• Jacket fiber (100% cotton) - This is a biological material as cotton is a plant-based textile.
• Bullet casing - Typically made of metals like aluminum, steel, or brass, this is a physical object.
• Glass fragments - Glass is a non-biological, inorganic material, so this would be considered physical.
• Ransom note - A ransom note, while made of paper (which is derived from wood, a biological source), is considered a physical piece of evidence in the context it is presented.
