Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.
The correct steps of endochondral ossification is:
- A periosteal bone collar develops.
- spongy bone and the medullary cavity form in the diaphysis.
- The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
- The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
- The spongy bone forms in epiphysis.
<h3>Which bones grow by endochondral ossification?</h3>
Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.
Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.
