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.

Answer:
Option-A
Explanation:
Fertilization refers to the fusion of the male and female gamete to form the zygote.
When the fertilization occurs inside the organism through insemination then it is known as the internal fertilization and when it occurs outside the organism like observed in the amphibians when male and female gametes fuse in the water is known as external fertilization.
Both are different type of fertilization but share a similarity that is the formation of a single cell called the zygote which grows into the embryo by the mitotic division. The embryo later develops into the organism.
Thus, Option-A is correct.
