The acetabulum is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the coxal joint.
The acetabulum is made up of the three bones that make up the coxal bone (hip bone). 
The ischium, which offers the lower and side limits to the acetabulum, makes up somewhat more than two-fifths of the structure. 
Less than two-fifths of the acetabulum's structure is provided by the ilium, which also serves as the top limit of the joint. 
The pubis, which is close to the midline, forms the remainder.
The acetabulofemoral joint (art. coxae), also known as the coxal joint, is the joint between the head of the femur and the acetabulum of the pelvis. 
Its main job is to support the weight of the body in both static (such as while standing) and dynamic (such as when walking or running) postures.

Answer:
The ability of body systems to increase their function, given the need to adapt, is known as the <u>physiologic reserve.</u>
Explanation:
The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
 
        
             
        
        
        
Answer:
Taxonomy chart for plants (mango) is given below :
1) The domain is eukaryote. 
2) Kingdom is plantae. 
3) Division is embrophyta. 
4) Class is dicotyledonae. 
5) Order is sapindales. 
6) Family is anacardiaceae. 
7) Genus is magnifera. 
8) Specie is indica. 
Explanation: 
Eukaryote are those organisms having true nucleus. Dicotyledons are those plants in which seeds have two cotyledons. Mango plant belongs to Angiosperm i. e. seeds are hidden in the ovary.
