Answer the following question given this paragraph: A species is a group of individuals that are genetically related and can breed to produce fertile young. Individuals are not members of the same species if their members cannot produce offspring that can also have children. The second word in the two word name given to every organism is the species name. For example, in Homo sapiens , sapiens is the species name. Q: A group of individuals that consists of genetically related individuals that can breed to produce fertile young is known as what? Choices: - colonies - community - population - species A:
species

Choices: - n-type and m-type - o-type and p-type - a-type and b-type - n-type and p-type A:
(Answer)
n-type and p-type
Ques: Answer the following question given this paragraph: Unlike energy, matter doesn't need to be constantly added to ecosystems. Instead, matter is recycled through ecosystems. Water and elements such as carbon and nitrogen that living things need are used over and over again. Q: Unlike energy, what doesn't need to be constantly added to ecosystems because it is recycled through ecosystems? Choices: - water - nutrients - vapor - matter A:
Ans: matter

Answer the following question given this paragraph: Energy is absorbed in the process of converting a liquid at its boiling point into a gas. As with the melting of a solid, the temperature of a boiling liquid remains constant and the input of energy goes into changing the state. The molar heat of vaporization of a substance is the heat absorbed by one mole of that substance as it is converted from a liquid to a gas. As a gas condenses to a liquid, heat is released. The molar heat of condensation of a substance is the heat released by one mole of that substance as it is converted from a gas to a liquid. Since vaporization and condensation of a given substance are the exact opposite processes, the numerical value of the molar heat of vaporization is the same as the numerical value of the molar heat of condensation, but opposite in sign. In other words, . Q: Energy is absorbed in the process of converting a liquid at its boiling point into a what? Choices: - mesh - plasma - solid - gas A:
(A).
gas
Ques:Answer the following question given this paragraph: Eventually plants evolved. Plants produce oxygen as a product of photosynthesis. Oxygen spread around the planet about 2.5 billion years ago. Many organisms died off because they could not handle the oxygen. But this development was extremely important for other life. Animals need oxygen to breathe. If photosynthesis had not evolved there would be no animals. Q: Because it produces oxygen, what plant process was necessary for the evolution of animals? Choices: - germination - death - reproduction - photosynthesis A:

Ans:photosynthesis
