Question

multiple choice 5 points what kind of tissue is the precursor to long bones in the embryo? fibrocartilage hyaline cartilage dense fibrous connective tissue elastic connective tissue multiple choice 5 points the most important characteristic for designating a bone as a \long bone\ is _. its location in the body its total length its length relative to other bones its elongated shape multiple choice 4 points mechanical stress applied to bone _ osteoblast activity in bone tissue increases has no affect on decreases

Explanation:

For question 4, hyaline cartilage is the precursor to long bones in the embryo. Fibrocartilage is tough and found in areas like intervertebral discs. Dense fibrous connective tissue is mainly for strength and attachment in ligaments and tendons. Elastic connective tissue provides elasticity in places like the aorta.
For question 5, a long bone is designated by its elongated shape rather than just location, total length, or length relative to other bones.
For question 6, mechanical stress applied to bone increases osteoblast activity as the bone responds to stress by building more bone tissue for strength.

Answer:

1. hyaline cartilage
2. It's elongated shape
3. Increases
