Accepted Answer

Bilateral symmetry

Question 3

Which tissue type is primarily responsible for lining cavities, open spaces, and surfaces in animal bodies?

Accepted Answer

Epithelial tissue

Question 4

Which of the following is a function of simple squamous epithelial tissue?

Accepted Answer

Question 5

Which connective tissue type forms the subcutaneous layer that attaches skin to underlying structures?

Accepted Answer

Loose connective tissue

Question 6

Which of the following best explains why elastic connective tissue is found in the walls of large arteries?

Accepted Answer

Question 7

Which connective tissue type is characterized by chondrocytes embedded in a hard, rubbery matrix and provides support in the embryonic skeleton of vertebrates?

Accepted Answer

Cartilage

Question 8

Which of the following is a major function of adipose tissue?

Question 11

Which feedback system is primarily responsible for maintaining homeostasis by counteracting internal changes?

Accepted Answer

Negative feedback system

Question 12

A patient is experiencing a rapid increase in body temperature due to infection. Which homeostatic mechanism will most likely be activated to restore normal temperature?

Accepted Answer
