Question

blood is classified as a connective tissue because ________. answer it provides support, it arises from mesenchymal tissue and has a nonliving fluid matrix, it contains fibroblasts, it connects parts of the body together, i dont know yet

Explanation:

To determine why blood is a connective tissue, we analyze each option:

• "It provides support": Connective tissues like bone/cartilage provide support, but blood's main role isn't support, so this is incorrect.
• "It arises from mesenchymal tissue and has a nonliving fluid matrix": Connective tissues originate from mesenchyme, and blood has plasma (nonliving fluid matrix) with cells, fitting connective tissue criteria.
• "It contains fibroblasts": Fibroblasts are in connective tissues like loose/dense connective tissue, not blood, so incorrect.
• "It connects parts of the body together": Connecting body parts is more about other connective tissues (e.g., tendons), blood's role is transport, so incorrect.

Answer:

B. it arises from mesenchymal tissue and has a nonliving fluid matrix
