Answer:
Smoking causes the hardening of the alveoli walls. This keeps them from extending or stretching out because of the loss of elasticity. In such a circumstance, it is hard to take up oxygen from the inspired air or to remove carbon dioxide from the circulation system. This would prompt partial or less trapping of the gases in the lungs.
With this damage due to smoking, the alveoli can not assist the bronchial tubes enough. The tubes also get damaged and cause a blockage or obstruction, which traps air inside the lungs. An excess of air caught in the lungs can give a few patients a barrel-chested appearance.
Answer:
As amoeba is a unicellular organism all the physiological processes are performed by the single cell.
Explanation:
The food is captured by the pseudopodia and after entering into the body it forms food vacuole. Then the food is broken down by enzymatic activities within the food vacuole and the simplified food absorbed by the cytoplasm.
The remaining undigested food is expelled by the plasma membrane. This is done by rupture of the cell membrane and the waste products diffused out of the plasma.
Most of the time the food captured by amoeba is absorbed more and less waste is formed.
Amoeba reproduces the process of binary fission. It is a type of asexual reproduction where the body is divided into 2, 4, 8.... then 16 and so on.. many cells. These small amoeboid cells grow and become new organisms.
As it is a single-cell organism, nutrition, assimilation, excretion, the reproduction process occurs at a fast rate.
Both plant cells and animal cells have mitochondria, A.
C. Upward; downward. As the hot rock rises, cooler rock flows downward to take its place next to the core, where it is heated and becomes buoyant enough to rise again later
