10; 2%
Of the chemicals that fall under the TSCA 10% have been tested for toxicity and 2% have been tested for endocrine, nervous, or immune system damage.
The Toxic Substances Control Act (TSCA) is a law issued by the United States Congress and used by the Environmental Protection Agency (EPA) to demand for documentation and testing requirements, and restrictions associated with chemical substances. Other substances such as foods and drugs are mainly removed from TSCA.
I think electric but im not sure tho.....
Answer:
Quorum sensing.
Explanation:
Quorum sensing may be defined as the phenomena by which the bacteria can detect the specific stimuli and respond towards the cell population density. This process helps in coordinating gene expression.
Quorum sensing is used in prokaryotes for the cell to cell signalling and cell communication as well. The main evolution of quorum sensing in bacteria was to relay the information and helps in cell signalling by releasing the specific toxins. From the evolutionary point, the organism that are capable of quorum sensing would survive more in their environment, adapt well in their environment.
Thus, the answer is quorum sensing.
Answer: medulla of the brain
The medulla of our brain is the control center of our heart rate. It either slows or speeds the heart beats per minute. If the medulla of the brain is not working correctly, our heart rate is also not being controlled correctly. We would not be able to live without the medulla. It helps in regulating blood pressure, breathing and transfer of neural messages from the brain to the spinal cord.
All systems have input, process, and output.
