Answer:
Homologous genes that are highly conserved.
Explanation:
Phylogenetic trees are diagrams that represent evolutionary relationship between organisms.
It is set to represent the hypothesis that a set of species evolved fro the same ancestor.
Anatomical similarities are considered in the construction of the trees.
However , two organisms can be placed in the same tree by comparing their genes.
If the two eukaryotes have genes that are highly conserved that similar.
Answer:
Patches of fibrocartilage formed in the healing of a fracture are called <u>soft callus</u>, whereas the bony collar formed around the fracture is called <u>hard callus</u>.
Explanation:
In the fibrocartilage or soft bone callus phase, the necrotic bone is removed by osteoclastia and dead soft tissues are being removed by macrophages. The fibroblasts are activated and a granulation tissue is generated that supposes the appearance of new vessels and, with them, the arrival of more connective tissue cells. A tissue called fibrous callus or fibrocartilage begins to form, composed of a poorly structured amalgam of fibrous tissue, cartilage, and amorphous bone.In hard callus, bone and later cartilage are deposited in the growing historical mass. The two collars of callus, fixed to the bone at some distance from the fracture, they grow upwards and towards each other, forming an arc on focus.
There are many ways to do this. You can either create a close approximation to what you think are the most relevant variables and hope your idea about the relevant variables was true.
Another way would be to do different kinds of experiments and hope you can deduce information from those experiments onto the subject that you would like to find an explanation for.
