Question 4

Species which has restricted distribution is called

Solution:

 

Correct Answer

Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. Another term for a species that is endemic is precinctive, which applies to species (and sub specific categories) that are restricted to a defined geographical area. A native species, such as a native plant, is one that is considered to have been endemic for a relatively long period of time.

Solution:

 

Oops! Wrong answer!

Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual’s immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection. When a sufficiently large percentage of a population has been vaccinated, this results in herd immunity. Vaccination is Artificial active acquired immunity.

Question 8

Which one of the following enzymes is found in human saliva?

Solution:

 

Correct Answer

  • Ptyalin is an enzyme in the saliva that catalyzes the hydrolysis of starch into dextrin and maltose.
  • Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. Only about 30% starch digestion takes place in the mouth cavity.
