Answer the following question given this paragraph: Figure 7.32 Thoracic Cage The thoracic cage is formed by the (a) sternum and (b) 12 pairs of ribs with their costal cartilages. The ribs are anchored posteriorly to the 12 thoracic vertebrae. The sternum consists of the manubrium, body, and xiphoid process. The ribs are classified as true ribs (17) and false ribs (812). The last two pairs of false ribs are also known as floating ribs (1112). Q: The sternum and 12 pairs of ribs with their costal cartilages make up what? Choices: - chest cage - the core - heart cage - thoracic cage A:
thoracic cage
Answer the following question given this paragraph: In a procedure called elemental analysis , an unknown compound can be analyzed in the laboratory in order to determine the percentages of each element contained within it. These percentages can be transformed into the mole ratio of the elements, which leads to the empirical formula. The steps to be taken are outlined below. Q: What is the name of the procedure where an unknown compound can be analyzed in the laboratory in order to determine the percentages of each element contained within it? Choices: - electrical analysis - chemical analysis - gaseous analysis - elemental analysis A:
elemental analysis
Q: Answer the following question given this paragraph: Accuracy describes how close an estimate is to a known standard. Q: What describes how close an estimate is to a known standard? Choices: - diversity - frequency - precision - accuracy A:
A: accuracy
Question: Answer the following question given this paragraph: Actually, almost all organisms obtain their energy from photosynthetic organisms. For example, if a bird eats a caterpillar, then the bird gets the energy that the caterpillar gets from the plants it eats. So the bird indirectly gets energy that began with the glucose formed through photosynthesis. Therefore, the process of photosynthesis is central to sustaining life on Earth. In eukaryotic organisms, photosynthesis occurs in chloroplasts . Only cells with chloroplastsplant cells and algal (protist) cellscan perform photosynthesis. Animal cells and fungal cells do not have chloroplasts and, therefore, cannot photosynthesize. That is why these organisms, as well as the non-photosynthetic protists, rely on other organisms to obtain their energy. These organisms are heterotrophs. Q: What is the function of chloroplasts that are found in plant and algal cells? Choices: - mitosis - spermatogenesis - glycolysis - photosynthesis A:
Answer: photosynthesis

Answer the following question given this paragraph: Chemical reactions always involve energy. When methane burns, for example, it releases energy in the form of heat and light. Other chemical reactions absorb energy rather than release it. Q: Chemical reactions always involve energy. when methane burns, for example, it releases energy in the form of what? Choices: - movement and light - light and sound - heat and movement - heat and light A:
**Answer**
heat and light

Answer the following question given this paragraph: When most people think of muscles, they think of the muscles that are visible just under the skin, particularly of the limbs. These are skeletal muscles, so-named because most of them move the skeleton. But there are two other types of muscle in the body, with distinctly different jobs. Cardiac muscle, found in the heart, is concerned with pumping blood through the circulatory system. Smooth muscle is concerned with various involuntary movements, such as having one's hair stand on end when cold or frightened, or moving food through the digestive system. This chapter will examine the structure and function of these three types of muscles. Q: What kind of muscle is found in the heart? Choices: - cord - respiratory - pulminary - cardiac A:
**Answer**
cardiac
