Answer:
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection
Explanation:
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.

The answer is A. this is caused by a mutation in the beta
thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual.
The alpha subunit is normal in people with sickle cell disease. When sickle
hemoglobin releases oxygen in the peripheral tissues, the molecules tend to
stick together and form long chains or polymers. These rigid polymers distort
the cell and cause it to bend out of shape from
the normative disc shape.
