I believe that the answer is B.
<span>Alternation of generation is what happens in the asexual reproduction of vascular plants in their gametes, as haploid cells that came from their gametes, spores fertilizes another plant becomes a diploid cell in the process.
In terms of vascular plants, they help maintain the water cycle. The property of these plants enables them to carry out this function is their well-developed vascular system. These type of plants are more evolved and developed than nonvascular plants because of its specialized characteristics like xylem, which is a tissue that is responsible for its framework and not only that, it is also has a greater mechanism for water transference. Another is phloem, which is responsible for food conduction.<span>

Bar graphs show patterns in data with variables that change over time; Whereas pie charts, show data as parts out of a whole, (such as 100%).
Answer: Myelin
Explanation:
The speed of the neurotransmission increases as we grow. The behavior of the teenager is quite different from the behavior of the adolescents.
They are more active, heroic and wants to take risk. This is because their brains are not completely developed till they reach the age of 25.
As they grow and reach the late 20s the white mater in the brain increases as the frontal lobe is the last part of the brain development.
Due to the development of the myelin in the frontal lobe the transmission of the signal increases at adolescence.
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.
