Answer:
The procedure by which the developing cartilage systematically gets substituted by the bone to produce the growing skeleton is termed as endochondral ossification. The columns of chondrocytes are after that get invaded by the metaphyseal blood vessels, and on the residual columns of the calcified cartilage the formation of bone takes place.
The following are the essential steps in the procedure of endochondral ossification:
1. The chondrocytes get enlarged and the enveloping matrix starts to calcify.
2. The enlarged chondrocytes die.
3. The growth of the blood vessels takes place surrounding the edges of the cartilage.
4. The perichondrial cells turn into osteoblasts and generate a superficial bone layer.
5. The osteoblasts substitute the calcified cartilage with the spongy bone.
B, coal is relatively inexpensive compared to the use of renewable energies such as solar and wind. coal also generates more energy in a shorter period of time than renewable energies.
Answer:
C
Explanation:
I'm pretty sure it's actually C and not A. It's asking for human-related release from greenhouse gases. Humans don't cause volcanic eruptions and aren't in control of wildlife's respirations. The solar cycles has to do with the magnetic flux that rises to the surface of the sun and lasts 11 years. Intensive agriculture increases pollution which harms the environment.
Pretty sure the answer is B. Hunting, as this will dwindle the population of elk.
