Explanation:

1.

Step1: Recall tissue - type facts

Connective tissue is the most abundant tissue in the human body. So the answer to the first question is True.

Step2: Analyze organ - tissue amounts

Not all organs have the same amount of connective tissue. Different organs have different compositions. So the answer to the second question is False.

Step3: Identify connective - tissue classes

Muscle is not a class of connective tissue. Connective tissue proper, cartilage, and bone are connective tissues. So the answer to the third question is D. Muscle.

Step4: Determine connective - tissue functions

Sending nerve impulses through the body is not a function of connective tissue. Connective tissue binds and supports, transports substances, and provides fuel reserves. So the answer to the fourth question is B. Sending nerve impulses through the body.

Step5: Understand connective - tissue origin

All connective tissues are derived from the same embryonic tissue. So the answer to the fifth question is B. They all develop from the same embryonic tissue.

Step6: Recall embryonic - tissue origin

The embryonic tissue that connective tissues develop from is mesenchyme. So the answer to the sixth question is D. Mesenchyme.

Step7: Define matrix characteristics

The matrix of connective tissue is non - living and made of cells. So the answer to the seventh question is A. It is non - living and made of cells.

Step8: Name matrix substance

The unstructured material that fills the space between matrix cells is ground substance. So the answer to the eighth question is B. Ground substance.

Step9: Identify strength - providing protein

Collagen fibers are strong and provide strength. So the answer to the ninth question is B. Collagen fibers.

Step10: Identify stretch - providing fiber

Elastic fibers are thin and provide the ability of a tissue to stretch and bounce back. So the answer to the tenth question is A. Elastic fibers.

Answer:

1. True
2. False
3. D. Muscle
4. B. Sending nerve impulses through the body
5. B. They all develop from the same embryonic tissue
6. D. Mesenchyme
7. A. It is non - living and made of cells
8. B. Ground substance
9. B. Collagen fibers
10. A. Elastic fibers
