Answer the following question given this paragraph: Flat Bones The term " flat bone" is somewhat of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs. Q: What type of bones serve as points of attachment for muscles and often protect internal organs? Choices: - sesamoid bones - irregular bones - short bones - flat bones A:
flat bones

Answer the following question given this paragraph: Life on Earth is based on carbon. A possible explanation is that no other element in the periodic table forms compounds that are so diverse in their chemistry and physical properties. Discuss the chemistry of carbon with regard to. Q: What element on the periodic table forms the most diverse compounds? Choices: - helium - oxygen - hydrogen - carbon A:
(Answer)
carbon
Ques: Answer the following question given this paragraph: Specialization in Anole Lizards. Specialization lets different species of anole lizards live in the same area without competing. Q: What lets different species of anole lizards live in the same area without competing? Choices: - concentration - cooperation - variation - specialization A:
Ans: specialization

Answer the following question given this paragraph: A chemical reaction is usually written in a way that suggests it proceeds in one direction, the direction in which we read, but all chemical reactions are reversible, and both the forward and reverse reaction occur to one degree or another depending on conditions. In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. If we run a reaction in a closed system so that the products cannot escape, we often find the reaction does not give a 100% yield of products. Instead, some reactants remain after the concentrations stop changing. At this point, when there is no further change in concentrations of reactants and products, we say the reaction is at equilibrium. A mixture of reactants and products is found at equilibrium. For example, when we place a sample of dinitrogen tetroxide (N2O4, a colorless gas) in a glass tube, it forms nitrogen dioxide (NO2, a brown gas) by the reaction N 2 O 4(g) 2NO 2(g) The color becomes darker as N2O4 is converted to NO2. When the system reaches equilibrium, both N2O4 and NO2 are present (Figure 13.2). Q: Chemical reactions are typically written to imply that they proceed in one direction - if they can occur in either direction, they are considered what? Choices: - singular - observable - reactive - reversible A:
(A).
reversible
Ques:Answer the following question given this paragraph: Mycorrhizae: The Symbiotic Relationship between Fungi and Roots A nutrient depletion zone can develop when there is rapid soil solution uptake, low nutrient concentration, low diffusion rate, or low soil moisture. These conditions are very common; therefore, most plants rely on fungi to facilitate the uptake of minerals from the soil. Fungi form symbiotic associations called mycorrhizae with plant roots, in which the fungi actually are integrated into the physical structure of the root. The fungi colonize the living root tissue during active plant growth. Through mycorrhization, the plant obtains mainly phosphate and other minerals, such as zinc and copper, from the soil. The fungus obtains nutrients, such as sugars, from the plant root (Figure 31.11). Mycorrhizae help increase the surface area of the plant root system because hyphae, which are narrow, can spread beyond the nutrient depletion zone. Hyphae can grow into small soil pores that allow access to phosphorus that would otherwise be unavailable to the plant. The beneficial effect on the plant is best observed in poor soils. The benefit to fungi is that they can obtain up to 20 percent of the total carbon accessed by plants. Mycorrhizae functions as a physical barrier to pathogens. It also provides an induction of generalized host defense mechanisms, and sometimes involves production of antibiotic compounds by the fungi. Q: Mycorrhizae functions as a physical barrier to what? Choices: - parasites - bacteria - vaccines - pathogens A:

Ans:pathogens
Ques: Answer the following question given this paragraph: Skepticism is an attitude of doubt about the truthfulness of claims that lack empirical evidence. Scientific skepticism , also referred to as skeptical inquiry, questions claims based on their scientific verifiability rather than simply accepting claims based on faith or anecdotes. Scientific skepticism uses critical thinking to analyze such claims and opposes claims which lack scientific evidence. Q: What is an attitude of doubt about the truthfulness of claims that lack empirical evidence? Choices: - conspiracy - speculation - independent variable - skepticism A:
Ans:
skepticism
