Answer:
D. All of the above
Explanation:
Hazardous waste is defined as waste that comprises organic or inorganic components or compounds that may have a negative influence on human health or the environment due to the waste's intrinsic physical, chemical, or toxicological characteristics.
Correct Option Is D. All of the above.
Liquids, solids, and enclosed gases can all be hazardous waste. Hazardous substances have one or more of the following characteristics: they are combustible, corrosive, lethal, or reactive. They can be waste from manufacturing operations, discarded used materials, or unused commercial products like cleaning fluids (solvents) or insecticides that have been discarded.
Answer:
amino acids
Explanation:
A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
<span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them.
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
Sorry its so long but that the answer i think >:) ur welcome

By lesioning the medulla in rats, scientists were able to cause a cessation in breathing. By electrically stimulating the amygdala in rats, scientists were able to trigger aggressive behaviour.
The medulla or medulla oblongata is found in the brainstem and is the structure that regulates autonomic functions of breathing, heart rate and blood pressure. Lesioning is a surgical term which describes the process of injuring a specific part of the brain. Therefore, when the medulla is lesioned, it can no longer function properly and the autonomic process of breathing is interrupted.
The amygdala is comprised of two nuclei within the temporal lobes of the brain and is considered part of the limbic system. Its functions include the processing of memory, decision-making and emotional responses. It has been shown that by electrically stimulating the amygdala in animals, their aggressive behaviour is increased.
