<u>Answer:</u>

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.

Describe the steps that bone goes through as it heals from a break.
lyudmila [28]

Answer:

Explained

Explanation:

Bone healing has three main processes and these stages are overlapping to each other. These processes are inflammation,bone production and bone remodeling.

Inflammation occurs immediately after the fracture and last several days. It enables clotting of blood. It provides initial structure stability and framework for new bone formation.  

Bone production occurs when the clotted blood formed by inflammation is replaced with fibrous tissues and cartilage as soft callous.

Bone remodeling is the final stage of the bone healing and it goes on for several months. Bone continues to form and compact. Bones returns to its original shape and the blood circulation in that area improves.
