In this sense‚ the host could be humans‚ animals or plants. These vectors have contributed to the epidemic of so many diseases. Different diseases are transmitted by different vectors but some ailments share common vectors. For instance female anopheles

VALENCY Valency can be defined as the combining capacity of an element.The electrons present in the outermostmost shell of an atom are known as valence electrons and they determine the valency.The valence electrons take part in chemical reaction and they determine the chemical properties of the elements.Let us take an example‚ Theatomic number of carbon is 6 Its configuration is =2‚4 It means valency of carbon is 4. In chemistry‚ valence‚ also known as valency or valence number‚ is the number

Introduction There are both virulent and non-virulent bacteria and fungi that grow on plants. It is difficult to distinguish between the two without proper inspection and diagnosis of the diseased plant to know whether the bacteria or the fungus in question is the virulent or non-virulent one. Therefore pure cultures need to be isolated to know with absolute certainty which is the causative bacteria or fungus. Potato dextrose agar is a good nutrient agar for mycelia to thrive on which is present
