Answer:
E. Malaria
Explanation:
Schizogony refers to the process of asexual reproduction through the process of multiple fission. The malaria parasite, <em>Plasmodium</em> species, enters the human body through the bite of female anopheles mosquitoes.
These mosquitoes carry haploid sporozoites in their saliva which are released into the bloodstream of human. The haploid sporozoites enter the liver cells where they multiply and increase their number through the process of multiple fission.
The process of schizogony in sporozoites of malaria parasite produces merozoites which are then released from the liver cells.
The choices are:
<span>A. Matrix protein
B. Hemagglutinin
C. An ion channel
D. Neuraminidase
</span>
The right answer is B. Hemaglutinin
Explanation:
Haemagglutinins are triangular rods. They allow the attachment of Influenzaviruses on the target cells of the respiratory tree. In the presence of red blood cells, a haemagglutination (liquid medium) is obtained.
<u>About the other components of Influenza virus:</u>Neuraminidase is a mushroom-shaped spike composed of a tetramer consisting of 4 subunits of a single glycoprotein. At 37 ° C, the neuraminidase destroys the bonds (virus - cells) and thus allows the release of neoformed virions in the external environment: it is elution.
The membrane protein M and the protein subunits of the nucleocapsid are antigenic and are the basis of the classification of Influenzavirus types A, B and C. They induce the synthesis of non-protective antibodies fixing the complement.
Answer:
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Answer:
West Nile virus (WNV) causes epidemics of febrile illness, meningitis, encephalitis, and flaccid paralysis. Since it was first detected in New York City in 1999, and through 2004, 16,000 WNV disease cases have been reported in the United States. Over the past 5 years, research on WNV disease has expanded rapidly. This review highlights new information regarding the virology, clinical manifestations, and pathology of WNV disease, which will provide a new platform for further research into diagnosis, treatment, and possible prevention of WNV through vaccination.
