Answer:1.yes

              2.yes

              3.may or may not

              4.yes

              5.yes true

Explanation:1. Like protozoa, yeast are also eukaryotic cells, which means that they possess a cell nucleus and other cell organelles.

2.Rhizobia are diazotrophic bacteria that fix nitrogen after becoming established inside the root nodules of legumes

3.Generally,an increase in temperature will increase enzyme activity. But if temperatures get too high, enzyme activity will diminish and the protein (the enzyme) will denature.Every bacterial species has specific growth temperature requirements which is largely determined by the temperature requirements of its enzymes.

4.A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.

5.There are some insects and animals which help in the transmission of pathogens from one human to another.They are called carriers.Houseflies,mosquitoes,cokroaches etc. are some carriers which sit on garbage,excreta and carry pathogens to eatables.Eg:Female Aedes:Dengue virus
