• define species. Ans: Species: Specie is a group of natural population which can interbreed freely among themselves; produce fertile offsprings but are reproductively isolate from all other such groups in nature. • Species are independent evolutionary units in which each unit has its own, distinct structural ecological and behavioral characteristics. 
• difference between virion and prion. Virion Prion • A complete mature and infectious virus is known as virion. • Viruses are fully understood. • The virions are composed of three parts: central core, capsid and envelope. • Their DNA and RNA contain information for their replication. • RNA and DNA are present in viruses. • They causes diseases like measles mumps etc. • These are infectious proteins. • They have not been fully understood. Their nature is very controversial. • They are composed of only proteins. • This protein contains information for its own replication. • Prions do not contain DNA and RNA. • They cause disease like mad cow disease and certain nervous mysterious diseases.
• write symptoms of aids. Ans: Four symptoms of AIDS: The patient has complex symptoms such as: 1) Severe Pneumonia 2) Rare vascular cancer 3) Sudden weight loss 4) General loss of immune system.
• define hepatitis. What are its types? Ans: Hepatitis: Hepatitis is an inflammation of the liver. • It is usually caused by viral infection, toxic agents or drugs. • It is characterized by jaundice, abdominal pain, liver enlargement, fatigue, and some times fever. • It may be mild or can be acute or chronic and can lead to liver cancer. types of hepatitis: • Hepatitis A (Infectious hepatitis) • Hepatitis B (Srum hepatitis) • Hepatitis C (Infusion hepatitis) • Hepatitis D • Hepatitis E • Hepatitis G &F.
• how hepatitis a is transmitted? Ans: Transmission of Hepatitis A: • Hepatitis A is most commonly transmitted by the fecal-oral through contamination of food or water by the feces of an infected individual. • An infected food handler is often involved in outbreaks have also been traced to day-care centers where contact may take place with feces. • Saliva contact, sexual contact and arthropods have also been implicated in transmission.
