PBS Week 1: Investigation Methods, Fingerprints, Hair, and Poly

Which part of the hair is responsible for its color?

• Cuticle

• Cortex

• Medulla

• Follicle

Describe a quality that is essential for a biomedical scientist when working in a laboratory.

• Ability to memorize large texts

• Attention to detail

• Skill in public speaking

• Proficiency in multiple languages

How does the medulla contribute to the structure of human hair?

• It provides strength and elasticity.

• It determines the hair's color.

• It is the innermost layer that may be absent in fine hair.

• It protects the hair from damage.

Analyze the role of communication skills in the work of a biomedical scientist.

• Communication skills are not important in laboratory settings.

• They are crucial for collaborating with other scientists and presenting findings.

• They are only needed for writing reports.

• They are only important for teaching roles.

Assess the importance of the cuticle in protecting human hair.

• The cuticle is the innermost layer and provides color.

• The cuticle is the outermost layer and protects the inner layers from damage.

• The cuticle is responsible for hair growth.

• The cuticle is not important for hair protection.

Discuss the significance of fingerprint analysis in forensic science.

• Fingerprint analysis is outdated and rarely used.

• It is a crucial tool for identifying individuals and linking them to crime scenes.

• It is only used for identifying deceased individuals.

• It is primarily used for creating criminal profiles.

Loop

What is the primary purpose of the link method in biology?

• To connect various biological data points to identify patterns and correlations

• To estimate the abundance of organisms in a given area

• To divide a study area into distinct zones for sampling

• To assess nutrient levels and soil properties

Which method is particularly useful in genetics for linking genes to specific traits or diseases?

• Link method

• Line transect sampling

• Zone sampling

• Grid sampling
