Bacteria and viruses can only survive on a dry surface area for 2 hours.
a. true
b. false

The given statement is True.

Humidity and temperature are the significant factors which support the growth and survival of bacteria and viruses. No bacteria or virus can survive in an environment with less than ten percent of humidity.  

In the dry conditions, the essential biochemical reactions will not take place. Also, food which is taken by bacteria and viruses, will not be dissolved properly. This will eventually limit the availability of energy, thereby hampering the survival of bacteria and viruses.

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

ur answer is e & d

explanation:
