Ques: Q: Calculations are described showing conversions between molar mass and what for gases? Read this paragraph and choose the correct option from the provided answers: Calculations are described showing conversions between molar mass and density for gases. Choices: - volume - length - weight - density A:

Ques: Q: Respiratory therapists or respiratory practitioners evaluate and treat patients diseases affecting what part of the body? Read this paragraph and choose the correct option from the provided answers: Respiratory Therapist Respiratory therapists or respiratory practitioners evaluate and treat patients with lung and cardiovascular diseases. They work as part of a medical team to develop treatment plans for patients. Respiratory therapists may treat premature babies with underdeveloped lungs, patients with chronic conditions such as asthma, or older patients suffering from lung disease such as emphysema and chronic obstructive pulmonary disease (COPD). They may operate advanced equipment such as compressed gas delivery systems, ventilators, blood gas analyzers, and resuscitators. Specialized programs to become a respiratory therapist generally lead to a bachelor's degree with a respiratory therapist specialty. Because of a growing aging population, career opportunities as a respiratory therapist are expected to remain strong. Choices: - byproduct , heart , and blood vessels - brain, stomach, heart - heart, lungs, stomach - lung, heart, and blood vessels A:
Ans: lung, heart, and blood vessels

Ques: Q: What organizational tool, arguably the best in all of science, lists all the known chemical elements, arranged by atomic number? Read this paragraph and choose the correct option from the provided answers: Appendix: Periodic Table of the Elements In this chapter, we present some data on the chemical elements. The periodic table, introduced in Chapter 3 "Atoms, Molecules, and Ions", lists all the known chemical elements, arranged by atomic number (that is, the number of protons in the nucleus). The periodic table is arguably the best tool in all of science; no other branch of science can summarize its fundamental constituents in such a concise and useful way. Many of the physical and chemical properties of the elements are either known or understood based on their positions on the periodic table. Periodic tables are available with a variety of chemical and physical properties listed in each element's box. What follows here is a more complex version of the periodic table than what was presented inChapter 3 "Atoms, Molecules, and Ions". The Internet is a great place to find periodic tables that contain additional information. One item on most periodic tables is the atomic mass of each element. For many applications, only one or two decimal places are necessary for the atomic mass. However, some applications (especially nuclear chemistry; see Chapter 15 "Nuclear Chemistry") require more decimal places. The atomic masses in Table 17.1 "The Basics of the Elements of the Periodic Table" represent the number of decimal places recognized by the International Union of Pure and Applied Chemistry, the worldwide body that develops standards for chemistry. The atomic masses of some elements are known very precisely, to a large number of decimal places. The atomic masses of other elements, especially radioactive elements, are not known as precisely. Some elements, such as lithium, can have varying atomic masses depending on how their isotopes are isolated. The web offers many interactive periodic table resources. For example, seehttp://www. ptable. Choices: - tide table - logic table - spreadsheet - periodic table A:
Ans: periodic table

Ques: Q: What category of joints is immovable? Read this paragraph and choose the correct option from the provided answers: Classification of Joints on the Basis of Function The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses. A synarthrosis is a joint that is immovable. This includes sutures, gomphoses, and synchondroses. Amphiarthroses are joints that allow slight movement, including syndesmoses and symphyses. Diarthroses are joints that allow for free movement of the joint, as in synovial joints. Choices: - amphiarthroses - sporozoans - diarthroses - synarthrosis A:
Ans:
synarthrosis
