The disease caused by the tapeworm Taenia solium is:
A. Trichinosis
B. Taeniasis
C. Filariasis
D. Ascariasis
Answer: Option B
Solution (By JKSSB Mock Tests)
Taeniasis is intestinal infection with adult Taenia solium (pork tapeworm). Cysticercosis is when larvae infect tissues. Ascariasis is roundworm, filariasis nematode, trichinosis Trichinella.
Explanation:
Chief cells (peptic cells) in the gastric mucosa secrete pepsinogen, which is converted to active pepsin by HCl. Pepsin digests proteins into peptides. Parietal cells secrete HCl and intrinsic factor. Mucous cells produce mucus that protects the stomach lining. G cells secrete gastrin hormone. Pepsin functions optimally at pH 1.8-2.0. The stomach thus initiates protein digestion.
Explanation:
Transpiration is the evaporative loss of water from the aerial parts of plants, primarily through stomata. It creates transpiration pull, aiding water and mineral transport. Guttation is loss of liquid water droplets from hydathodes. Evaporation is a physical process from any surface. Condensation is change from vapour to liquid. Transpiration also cools the plant.
Explanation:
Transduction is the transfer of bacterial DNA from one bacterium to another by a bacteriophage. Generalized transduction occurs when phage accidentally packages host DNA; specialized transduction involves specific genes near the prophage integration site. Conjugation needs direct contact, transformation free DNA.
