It can be anything that can be used purposefully as a weapon in bioterrorism or biological warfare (BW).
One example is - A culture of Bacillus anthracis, the anthrax bacillus.
Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results.

Rodrigo wants to find more ways to improve his latest design. Which of the following should he try?
(CHOOSE ALL THAT APPLY)
A - a more concentrated solution
B - a less concentrated solution
C - better insulation
D - less insulation
E - a greater amount of solution
F - a lesser amount of solution
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option are option C,E that is better insulation and a greater amount of solution.
Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
To improve his latest design Rodrigo should use a better insulation and a greater amount of solution.
Therefore, the correct option are option C,E.

Explanation:
Answer:
The correct answer would be B. Ingestion, digestion, absorption, elimination.
Digestion refers to the breakdown of complex compounds into simpler elements.
The process of the digestive system can be sequenced as:

Explanation:
if a cell is without water it has a high salinity while fresh water doesnt so the water rushes in and burst the cell
Mitosis or M phase involves the division of the nucleus, while cytokinesis involves the division of the cytoplasm.
Mitosis or M phase is the process by which a cell divides into two identical daughter cells, while cytokinesis is the final stage of cell division where the cytoplasm of the parent cell is divided into two separate cells.
So, the main difference between mitosis or M phase and cytokinesis is that mitosis involves the division of the nucleus, while cytokinesis involves the division of the cytoplasm.
During mitosis, the DNA in the nucleus is replicated and then divided equally between the two daughter cells. This is followed by cytokinesis, where a contractile ring forms and pinches the cytoplasm in two, creating two separate cells.
Therefore, mitosis and cytokinesis are separate but coordinated processes that together result in the division of cells during cell division.
