Question 9

Which of the following best describes the thoracic cage and its function?

Accepted Answer

It is formed by the ribs, sternum, and thoracic vertebrae and protects the heart and lungs.

Question 10

Accepted Answer

Cartilage tissue; found in the trachea and joints.

Question 11

Which of the following best explains the role of inorganic components in bone tissue?

Accepted Answer

Accepted Answer

The individual was a child or infant.

Question 13

Which of the following best describes the difference between spongy bone and compact bone?

Accepted Answer

Spongy bone contains trabeculae and is found at the ends of long bones, while compact bone forms the shaft and provides strength.

Question 14

A slide shows stratified squamous epithelium. Which function is most likely associated with this tissue type?

Accepted Answer

Protection against abrasion.

Question 15

Which of the following best describes the function of sebaceous glands?

Accepted Answer

They produce sebum to lubricate and waterproof the skin and hair.

Question 16

A student is using a microscope with a $$4	imes$$ objective lens and a $$10	imes$$ ocular lens. What is the total magnification, and which formula is used?
