Answers
1- Emphysema is a disease of the lungs that usually develops after many years of smoking. Along with asthma and chronic bronchitis, emphysema belongs to a group of lung diseases known as chronic obstructive pulmonary disease (COPD).
2- Ruminant stomachs
Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum. Rumen microbes ferment feed and produce volatile fatty acids, which is the cow's main energy source.
3- synovial joint
The wrist is an ellipsoidal (condyloid) type synovial joint, allowing for movement along two axes. This means that flexion, extension, adduction and abduction can all occur at the wrist joint. All the movements of the wrist are performed by the muscles of the forearm.
4- The bean seed absorbs water through the micropyle and becomes turgid resulting in breaking of the testa. The radical emerges out and grows downwards to form the roots system. The arched hypocotyl grows straight upward making the cotyledons emerge out of the soil thus making it an epigeal type of germination.
5- The digestive glands (salivary glands, pancreas, liver, and gallbladder) produce or store secretions that the body carries to the digestive tract in ducts and breaks down chemically.
