Q: Dissolved oxygen in seawater is critical for sea creatures, but as the oceans warm, oxygen becomes less what? Read this paragraph and choose the correct option from the provided answers: Introduction Coral reefs are home to about 25% of all marine species. They are being threatened by climate change, oceanic acidification, and water pollution, all of which change the composition of the solution we know as seawater. Dissolved oxygen in seawater is critical for sea creatures, but as the oceans warm, oxygen becomes less soluble. As the concentration of carbon dioxide in the atmosphere increases, the concentration of carbon dioxide in the oceans increases, contributing to oceanic acidification. Coral reefs are particularly sensitive to the acidification of the ocean, since the exoskeletons of the coral polyps are soluble in acidic solutions. Humans contribute to the changing of seawater composition by allowing agricultural runoff and other forms of pollution to affect our oceans. Solutions are crucial to the processes that sustain life and to many other processes involving chemical reactions. In this chapter, we will consider the nature of solutions, and examine factors that determine whether a solution will form and what properties it may have. In addition, we will discuss colloidssystems that resemble solutions but consist of dispersions of particles somewhat larger than ordinary molecules or ions. Choices: - insoluble - abundant - saturated - soluble A:
soluble

Q: Q: What are the bones in partly movable joints held in place by? Read this paragraph and choose the correct option from the provided answers: Partly movable joints allow only very limited movement. Bones at these joints are held in place by cartilage. The ribs and sternum are connected by partly movable joints. Choices: - socket - tendons - collagen - cartilage A:
A: cartilage

Q: Q: An alternative to inclusive fitness is group selection, a type of what scenario where small groups of organisms of the same species are effectively acting as single (perhaps colonial) organisms? Read this paragraph and choose the correct option from the provided answers: Group selection A proposed alternative to inclusive fitness (sometimes known as kin selection) is the concept of group selection. In this type of evolutionary scenario, small groups of organisms of the same species are effectively acting as single (perhaps colonial) organisms. It is the reproductive success of the group (rather than individuals within the group), compared to other groups of the organism that is the basis of selection. Groups that display cooperative and altruistic traits have a selective advantage over groups that do not. Again, the mathematical analysis is similar (and it has been claimed that mathematically group and kin selection are equivalent).169 The costs of a trait must be offset by the benefits, but now the key factor is membership in a particular group (and typically, members of a group tend to be related to one another). The life cycle of the bacterium Myxococcus xanthus provides an example of this type of behavior. When environmental conditions are harsh, the cells aggregate into dense, 100 m diameter, "fruiting bodies", each containing ~100,000 stress resistant spores. When the environment improves, and prey becomes available, the spores are released en mass and return to active life. They move and feed in a cooperative manner through the release of digestive enzymes, which because they are acting in a quorum mode, can reach high levels.170 A well-coordinated group is expected to have a significant reproductive advantage over more anarchic collection of individuals. Choices: - introductory - combination - molecular - evolutionary A:
A: evolutionary
