Welcome to your Trace Evidence Quiz Part 1 (Hair & Fiber)
3.
What does the term ‘isotropic’ mean in the context of glass?
4.
The application of micro-Raman spectrometry to fiber analysis allows:
6.
Assertion and Reason Question
Assertion (A): Multiple impacts on the glass cause radial and concentric cracks.
Reason (R): Radial cracks originate from the impact point and propagate away, while concentric cracks make a circle around the impact point.
8.
Assertion and Reason Question:
Assertion (A): Natural Fibers that have not been greatly altered in physical composition or characteristics by processing.
Reason (R): Coloring and treatments that improve merchandising or performance do change the classification of natural fibers.
9.
The growth of hair and fur occurs:
12.
Consider the following statements regarding Coir:
(a) Comes from the husk of coconut.
(b) Dark brown or opaque.
(c) Chemical tests for lignin are negative.
(d) Very light and elastic fiber.
Code:
14.
DNA can be isolated from the following part of hair:
(i) Root (ii) Cortex (iii) Cuticle (iv) Medulla
19.
Assertion and Reason Question
Assertion (A): In SEM, the electron beam causes interactions slightly below and at the surface of the sample, leading to the emission of protons and neutrons.
Reason (R): The emitted protons and neutrons are then converted to an electrical signal by an appropriate detector.
21.
Which of the following techniques can be used in the analysis of fibers?
24.
What role do pigments play in the composition of paint?
25.
