It  is  false that  in  plant  by    life   cycle,eggs  and  sperm  are   produced mitosis.
  Flowering  plant   go  through  a  complicated    double   fertilization  process  that  involves  a lot  of  sperm.pollen   grain  is  produced  by process  of  meiosis  in  which  sex  cell  divides  its  so  that   exactly  half  of  the  genetic  code  is in  a  cell.
        
             
        
        
        
Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’.  DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome. 
Have an awesome day! :)
 
        
             
        
        
        
Answer:
A pandemic is an epidemic disease extended across wide regions, thereby affecting many countries and even continents, while endemic diseases affect the people from only one country or a specific region. Human Immune Deficiency (HIV) is an RNA virus whose life cycle is composed of the following stages: 1) binding to the cell host and membrane fusion, 2) subsequent reverse transcription into DNA and integration into genome host 3) proliferation (i.e., successive replication cycles) by using the cellular machinery of the host 4) new assembly and budding of the virus. The acquired immune deficiency syndrome (HIV/AIDS) occurs when the host immune system is seriously damaged by the HIV infection, this being the latest stage of infection. It is known that HIV/AIDS is more prevalent in the female population, while according to ethnic groups, it is more prevalent in African-American and Hispanic/Latino populations in the USA. The life expectancy in HIV-infected patients has notably improved in the last years and, currently, people with this disease can expect to live over 70 years or even more.
