Answer:
b) avascular
Explanation:
Blood supply is an important factor necessary for quick healing of an injury. The cartilage is <em><u>an avascular tissue</u></em>, meaning there is no blood supply to the cartilage.
The prolonged recovery of this injury is basically due to the physiological fact that the cartilage is avascular. Tissues that have blood supply heal faster when damaged, when compared to damaged cartilages lacking blood supply.
Since, the options have not been given the question is incomplete. The complete question is as follows:
The people of Treasure Island Beach have been struck with a rash that seems to be infecting almost everyone in town. The staff of the hospital is working to design a study of this mysterious disease. They decide to do a cross-sectional study because cross-sectional or prevalence studies are known for
1. providing the information necessary to test for the most effective treatment of an illness or condition.
2. concurrently describing characteristics and health outcomes at one specific point in time.
3. supplying entire populations with therapeutic interventions on an epidemiologically sound basis.
4. quickly identifying cause and effect relationships that can serve as a basis for treatment.
Answer: 2. concurrently describing characteristics and health outcomes at one specific point in time.
Explanation:
The cross-section or prevalence studies are used for medical, biology and social science disciplines. These studies analyze the data taken from the representative subset of the population at specific intervals of time or at one specific point of time. This can be used to study the effect of disease over different point of time.
According to the given situation, the cross-sectional study should be performed on subjects affected by the rash to determine the health outcomes at different or specific point of time.
