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.

Temperature is a quantitative measurement because it can be "measured". Quantitative data is where you record data that is measurable. Qualitative data is research collected from observations.
Oceanic crust is thinner and denser than continental crust.
