Answer:

a. Osteogenic cells can differentiate into osteoclasts

Explanation:

Osteoblasts are the cells that are formed from osteogenic cells. The osteogenic cells enter the process of bone formation. There is a secretion of organic compounds and salts to form osteoblast. Osteoclasts are the very large cells that are formed when many monocytes fuse together and are concentrated in endosteum. Osteoclasts are the cells responsible for bone resorption.

Bone marrow is the soft connective tissue of bone that includes red bone marrow and yellow bone marrow. Red bone marrow is _____
Sever21 [200]

Answer:

Bone marrow is the soft connective tissue of bone that includes red bone marrow and yellow bone marrow. Red bone marrow is <u>heteroglobic</u> (blood cell forming) and contains <u>redactive</u> connective tissue, immature blood cells, and fat.

In children, red bone marrow is located in the <u>cyclonic</u> bone of most of the bones in the body as well as the <u>antebellum</u> of long bones. Much of the red bone marrow degenerates and turns into yellow bone marrow as children mature into adults. As a result, adults have red bone marrow only in selected portions of the <u>irregular</u> skeleton. Some of these include the <u>dismantled</u> bones of the skull, the vertebrae, the ribs, the sternum, and the hip bones.

Which statement correctly describes cancer formation?
AleksandrR [38]

Answer:

Cancer is formed when there are mutations in a number of genes.

Explanation:

Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.

Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).
