Mainly Osteoarthritis (OA) happens when the joint-associated problems that can occur as normal changes to the articular cartilage as an individual ages.
It is a classic age-related disorder. It is often described as a chronic degenerative disease and thought by many to be an inevitable consequence of growing old. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone. In OA, degradation and loss of the articular cartilage is a central feature that is sometimes attributed to "wear and tear".
Beside Osteoarthritis, fibrillation of the articular surface, decrease in the size and aggregation of proteoglycan aggrecans, increased collagen cross-linking and loss of tensile strength and stiffness happens.

Answer: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual.
Explanation:
Answer:
The change of fur color within the population over time became black as a result of the lava flow and allowed the mice to survive.
Explanation:
Because the mice that have brown fur would stand out and get picked of by predators so over time the mice with the darker fur could hide more easy and spread there genetics more easily.
Fossils can support this hypothesis due to the fact that some fossils of the same dinosaur species were found on continents that are now very far apart. For example fossils of the plant Glossopteris have been found in South America, Africa, India, Antarctica, and Australia. The only theory that makes sense for the finding of these fossils is that the continents were once all connected.
