Question

select all the correct answers.
liver tissue is a combination of many types of cells. in addition to other tissues, it contains connective tissue and epithelial tissue. which two sentences correctly identify the roles of these tissues?

• connective tissue supports the framework of the liver, and epithelial tissue protects the liver.
• connective tissue helps to send impulses to the brain, and epithelial tissue helps in contraction and relaxation.
• connective tissue helps with contraction and relaxation, and epithelial tissue supports the framework of the liver.
• connective tissue forms the lining of the liver, and epithelial tissue helps to send impulses to the brain.
• connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver.

Explanation:

1. Recall the functions of connective and epithelial tissues:

• Connective tissue functions include providing support, holding organs in place, etc. Epithelial tissue functions include protection, forming linings of organs, etc.
• Analyze each option:
• Option 1: Connective tissue supports the framework (matches its supportive role), epithelial tissue protects (matches its protective role) – correct.
• Option 2: Sending impulses is nervous tissue, contraction/relaxation is muscle tissue – incorrect.
• Option 3: Contraction/relaxation is muscle tissue, connective tissue (not epithelial) supports framework – incorrect.
• Option 4: Lining is epithelial, sending impulses is nervous – incorrect.
• Option 5: Connective tissue holds liver in place (matches its role), epithelial tissue forms lining (matches its role) – correct.

Answer:

A. Connective tissue supports the framework of the liver, and epithelial tissue protects the liver.
E. Connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver.
