Answer:
1. hyaline cartilage
2. a fibrocartilage
Explanation:
In endochondral ossification to produce fetal vertebrae, cartilage is substituted with a bone. The process of endochondral ossification includes the development of hyaline cartilage, also called the cartilage model. The hyaline cartilage develops from the chondroblasts derived from mesenchymal cells. The division of chondroblasts results in the growth of hyaline cartilage. It is followed by the development of the primary ossification center wherein the cartilage tissue is replaced with the bone matrix.
During the repair of these bones, a fibrocartilage callus is formed. Fibroblasts present in the site where the bone is broken produce collagen fibers and the cells derived from periosteum develop into chondroblasts and begin to produce fibrocartilage in this region. The fibrocartilage and collagen fibers together make the fibrocartilage callus that joins the broken ends of the bone.
Tundra ecosystem is cold and sunlight is short. Plants need sunglight and warmth in order to grow, thus plants in tundra are shorter and cloers to the ground since the ground is warmer than the air
The answer is ground hope that helps
Out of the following given choices;
A) her sex.
B) how tall she is.
C) how long her hair is.
D) the color of her eyes.
The answer is C. The length of hair is not determined by
genetics but rather by the time period of the growth phase (anagen phase) of
the hair follicle, before shedding in the telogen phase. The longer the anagen
phase the longer the hair will be before shedding. The hair on the head has
longer anagen phase compared to hair in regions such as the eyebrows.
