Q: In the physical sciences, an ion (/an, -n/) is a particle that has a non-zero net electrical charge, such as an atom or molecule whose total number of electrons is not equal to its total number of protons. A cation is a positively-charged ion, while an anion is negatively charged. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds, such as salts.
Can we conclude that an anion is any atom or group of atoms with a positive charge?
OPTIONS:
- no
- yes
A: no

Q: These frogs are suggested to be kept in a group of two or more due to their social nature. Despite being fully aquatic, the African dwarf frog still needs to be able to reach the surface to breathe. These amphibians are not great swimmers, so water currents should be kept low and deep tanks may pose a challenge to their ability to breathe. In the wild, the Congo forest floods yearly to a depth of 24 inches or more, so any depth less than that will be suitable. They also should be kept in an enclosure with a secure cover to prevent escape and plenty of hiding spaces as in the wild they tend to be prey to a variety of animals and open spaces cause skittish behavior. The frogs eat any smaller fish. The optimum water temperature is 75--82 F. The pH of the water should be maintained between 6.5 and 7.5. These frogs cannot survive out of water for longer than 20 minutes in low humidity, as they dry out.
Can we conclude that can african dwarf frogs survive out of water?
OPTIONS:
- no
- yes
A:
yes
