PLTW HBS Final Review

How can directional terms and regional terms help describe location in the body?

• They help to specifically tell us where to look.

• they tell us gibberish.

• They help confuse us.

• They give detailed directions of where not to look.

What features of structure and function are common to all humans?

• Internal organs

• body systems

• blood type

• bones, muscle, skin.

What are the main types of tissue in the human body?

• Epithelial, Connective, Muscle and Nervous.

• Epithelial, Connective, and Mucle

• Epithelal, Connectve, Muscle and Nervous.

• Pithlial, Connctiv, Muscl and Nrvous.

How does the structure of a type of human tissue relate to its function.

• Epithelial: Layered: to line organs and body cavities.

• Connective: Matrix: to fill in spaces so bone, cartilage etc. can join

• Muscle: to allow movement for the muscles

• Nervous: Long Axons: so signals can travel long distances, and branches connections.

• None of the above

What are the functions of the human skeletal system?

• Axial skeletal: skull and trunk: to protect soft organs

• Appendicular skeleton:arms and legs: provides attachment points for muscles that allow movement.

• All are correct.

• None are Correct

What is forensic anthropology?

• The study of human bones to determine information about the deceased and decide cause of death and whether a crime was committed.

• The study of human bones.

• The thing people do on crime shows to sole the case.

• Provide definitive evidence 100% of the time.

How can features of bone be used to determine information about a person's gender, ethnicity, age or stature?

• Gender=skull/pelvis

• Ethnicity= nasal index

• Pelvis= age

• Humerus/Femur=height

• The Humerus and Femur tell everything.

What is the structure and function of DNA?

• The structure is a double helix. Each gene codes for a protein, and each protein determines a trait.

• Each gene codes for a protein, and each protein determines a trait.

• Double helix

• half of a double helix.

How does DNA differ from person to person?

• Each person has different sequences of bases.

• Each person has different sequences of proteins

• Each person has different sequences of RNA

• Each person has different sequences of traits.

How can tools of molecular biology be used to compare the DNA of two individuals?

• DNA extracted from person to person then performs PCR- increases the DNA making it bigger than original.They help cut the DNA- restriction enzymes running them through gel electrophoresis- analyzes size of each DNA fragment. The enzymes cut the DNA in a different place so RFLP's look different on gels.

• RNA extracted from person to person then performs PCR- increases the RNA making it bigger than original.They help cut the RNA- restriction enzymes running them through gel electrophoresis- analyzes size of each RNA fragment. The enzymes cut the RNA in a different place so RFLP's look different on gels.

• They help cut the DNA- restriction enzymes running them through gel electrophoresis- analyzes size of each DNA fragment. The enzymes cut the DNA in a different place so RFLP's look different on gels.
