Answer:
<u>Hyaline cartilage model formation</u> is the event that should proceed all others during endochondral ossification.
Explanation:
- The Greek root word for cartilage is ‘chondro’. Endochondral ossification is the systematic formation or replacement by bones to develop the growing skeleton from a growing cartilage.
- Mesenchymal cells are converted to chondroblasts to chondrocytes and then to a hyaline cartilage model. This leads to the development of long bones of both the axial (ribs) and the appendicular skeleton (limb bones).
- The sites of endochondral ossification are the physis, epiphysis, and cuboidal bones.
- The five main steps involved in endochondral ossification are –
- Bone collar formation
- Cavitation
- Periosteal bud invasion
- Diaphysis elongation
- Epiphiseal ossification
Answer:
hmm let me think real quick ok i got the answer
Explanation:
its for both Answer and Explanation: An uncorrected error in DNA transcription can lead to a potential change in amino acid sequence in the protein produced from the transcription. If any change in amino acid sequence does occur, it could either result in a disadvantage to the organism or may result in an advantage.
Answer:
The statement is False
Explanation:
Osmotic pressure is created by the movement of water across the semi-permeable membrane. In osmosis water moves from an area which is having low solute concentration to the area which is having high solute concentration.
So in osmosis, the movement of water takes place not molecules. This pressure is caused by differences in solute concentration across the plasma membrane and water moves to high concentration to equalize the pressure. Therefore the statement is wrong.
Answer: The correct answer is : D. sagittal suture
Explanation: The sagittal suture connects the two parietal bones of the skull, it is a type of synartrotic fibrous joint. Fibrous joints with very little or no mobility are called synartrotic, the bones are held together by fibrous connective tissues. Synarthrosis occurs where there is bone growth. Synarthrosis protects and supports ligaments and muscles.
I believe it would be the last one since it is from the national institutes of heath, and that it the most reliable source.
