Answer:They disagreed with the practice of slavery and took steps to free hundreds of enslaved people during their lifetimes.
Explanation:
Add a catalyst
- would increase rate of reaction;
Because adding catalyst would lower activation energies.
Decrease the concentration of a reactant
- would decrease rate of reaction; because there would be less molecule
Decrease the surface area of a solid reactant
- decrease rate of reaction; less collisions because more particles would become isolated
Increase the temperature
- Would increase reaction; Because it would accelerate the movement of the particles and make them colliding faster
A bailment in which both the bailee and bailor derive some benefit, and, as a result, each has rights and duties, is known as a mutual-benefit bailment.
A bailment begins when a man acquires property previously owned by another person. Men take over the goods for specific reasons and for specific periods of time. For a contract to be a valid surety, a man must put his property under the control of another person. The goods are then safely returned after the specified period.
The person who surrenders the property is the bailer. The person who keeps the property is the bailee, and the bailee does not acquire the ownership of the property. A bailment is a short-term contract that can be terminated in various ways, including by mutual agreement of the parties, actions of either party, damage caused to property, and operation of law.
The most common type of bailment is a mutual-benefit bailment, where both parties benefit from the agreement. There are five types of mutual-benefit bailment: leasing, labor and services, mortgages, transportation, repository and parking.

Yes, if the biospecimens are de-identified then the research is no longer considered human subjects research.
Option: C
Explanation:
It is in the norms that in same type of research, both the researchers need to maintain some ethics and rules that if they do same type of experiments and use same materials they should acknowledge the other or take permission before doing that.
Here researcher A is conducting research on emphysema using bio specimen from human subjects and researcher B is doing research on lung cancer. He also need bio specimen. But as it is mentioned in the consent form that specimen is de identified so no problem for researcher B in using same specimen like researcher A.
