Infectious agents vary in their size and shape. Which infectious agent tends to be the smallest? A.
parasite
B.
fungi
C.
viruses
D.
bacteria

The correct answer is option C, that is, viruses.

Explanation:

An infection occurs when a foreign species moves inside the body of an individual and causes harm. The species utilizes the body of that person to reproduce, sustain itself, and colonize. These infectious species are called pathogens. The examples of pathogens are viruses, bacteria, prions, and fungi.

Of the given options, viruses are the smallest infectious agent. The viruses are basic particles, which must infect a host cell to reproduce and develop. Viruses utilize the host cells metabolic machinery to double themselves.

oh it is true if thats what you are asking

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
