Answer: Talc is a nonrenewable resource.
Explanation:
Talc is a mineral, which counts as a nonrenewable resource. Minerals, fossil fuels, and ores are nonrenewable resources because they do not regenerate or renew themselves at a quick enough rate and often take long periods of time to replenish. 
 
        
             
        
        
        
Answer:
The dry-out material contains spores of anthrax-causing bacteria
Explanation:
<em>Anthrax is a disease caused by a bacteria known as Bacillus anthracis. Susceptible animals get infected by anthrax when the spore of the bacteria gets into their bodies, become activated, multiply and produce toxins.</em> 
The spore serves primarily as a propagating structure and also as an agent for transmitting infections. It can be transmitted by air, water, food or any other means. Bacterial spores usually have the capability to tolerate harsh environmental conditions and only become inactivated when conditions are favourable.
The dry granular powdery material constituent of the letters received by the U.S. senators must have been spores of <em>Bacillus anthrasis</em>

Answer:
C) parfocal.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye. 
A microscope is said to be parfocal if its lense is binocular and they can both be in focus. 
Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal. 
 
        
             
        
        
        
Evaporation<span> occurs when water changes from a liquid state to a gaseous state. It can happen anywhere there is water – in the soil, lakes, oceans and plants. When it occurs in plants, water is lost through microscopic pores in the plant's leaves</span>
