Answer:
Pericarditis,an infection with an accumulation of fluid in the pericardial sac,can lead to cardiac attack ,as the fluid compress the heart and stops from beating.
Explanation:
Pericarditis is mainly caused by viral infection in the respiratory tract.Pericarditis is an autoimmune disorder as they release antibody which attack body's own tissue and cells.
Pericarditis mainly affect people with age between 20-50

The symptoms include Chest pain,Cardiac attack and some times cause death.
Pericarditis may be acute as it happens suddenly and does't lasts for longer time.
For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

The shoulder (pectoral) and pelvic girdles are both structures for limb articulation. The shoulder girdles are to the upper limbs as the pelvic girdle is to the lower limbs. Shoulder girdles connect the upper arms with the axial skeleton and consist of the clavicle and scapula.
The pelvic girdles consist of the hip bones, the sacrum and the coccyx and are located between the abdomen and the thighs.
Photosynthetic plants use carbon dioxide to generate and function. Plants need energy (glucose) to survive. They exist to absorb carbon dioxide from the atmosphere. One of their end products is oxygen. Animals take in oxygen and release carbon dioxide while the plants take in carbon dioxide and release oxygen. This is balance.
