Answer the following question given this paragraph: All living things are made of matter . In fact, matter is the "stuff" of which all organisms are made. Anything that occupies space and has mass is known as matter. Matter, in turn, consists of chemical substances. It is the carbons, hydrogens, oxygens and other elements that combine to form molecules, compounds, organelles, cells and eventually tissues, organs and organisms. In addition to being made of matter, all living organisms also need energy to survive. Q: Anything that occupies space and has mass is known as what? Choices: - opaque - solid - dense - matter A:
matter
Answer the following question given this paragraph: Fungi are heterotrophs, meaning they obtain food from outside themselves. Q: Organisms that obtain food from outside themselves (i.e. they don't make their own food) are known as what? Choices: - autotrophs - zygotes - fungi - heterotrophs A:
heterotrophs
Q: Answer the following question given this paragraph: The Breasts Whereas the breasts are located far from the other female reproductive organs, they are considered accessory organs of the female reproductive system. The function of the breasts is to supply milk to an infant in a process called lactation. The external features of the breast include a nipple surrounded by a pigmented areola (Figure 27.17), whose coloration may deepen during pregnancy. The areola is typically circular and can vary in size from 25 to 100 mm in diameter. The areolar region is characterized by small, raised areolar glands that secrete lubricating fluid during lactation to protect the nipple from chafing. When a baby nurses, or draws milk from the breast, the entire areolar region is taken into the mouth. Breast milk is produced by the mammary glands, which are modified sweat glands. The milk itself exits the breast through the nipple via 15 to 20 lactiferous ducts that open on the surface of the nipple. These lactiferous ducts each extend to a lactiferous sinus that connects to a glandular lobe within the breast itself that contains groups of milk-secreting cells in clusters called alveoli (see Figure 27.17). The clusters can change in size depending on the amount of milk in the alveolar lumen. Once milk is made in the alveoli, stimulated myoepithelial cells that surround the alveoli contract to push the milk to the lactiferous sinuses. From here, the baby can draw milk through the lactiferous ducts by suckling. The lobes themselves are surrounded by fat tissue, which determines the size of the breast; breast size differs between individuals and does not affect the amount of milk produced. Supporting the breasts are multiple bands of connective tissue called suspensory ligaments that connect the breast tissue to the dermis of the overlying skin. Q: Breasts are considered accessory organs of what body system? Choices: - digestive system - nervous system - lymphatic system - female reproductive system A:
A: female reproductive system
Question: Answer the following question given this paragraph: The structures of both trifluoramine and hydroxylamine are similar to that of ammonia. Q: The structures of both trifluoramine and hydroxylamine are similar to that of what? Choices: - hydrogen - magnesium - nitrogen - ammonia A:
Answer: ammonia

Answer the following question given this paragraph: The pond on the left is covered with algae because there is too much nitrogen in the water. The red-shaded area in the map on the right is a dead zone in the Gulf of Mexico. It's called the hypoxic ("low oxygen") zone in the figure. Q: What does hypoxic mean? Choices: - standard oxygen level - Oxygen rate - higher oxygen - low oxygen A:
**Answer**
low oxygen
Answer the following question given this paragraph: NaN3 is 1.847 g/cm . What is the volume of the gas produced compared to the solid reactant? Suggest a plausible reason to explain why skin burns can result from the inflation of an airbag during an automobile accident. Under basic conditions, the reaction of hydrogen peroxide (H 2O2) and potassium permanganate (KMnO4) produces oxygen and manganese dioxide. During a laboratory exercise, you carefully weighed out your sample of KMnO4. Unfortunately, however, you lost your data just before mixing the KMnO 4 with an H2O2 solution of unknown concentration. Devise a method to determine the mass of your sample of KMnO4 using excess H2O2. Carbonated beverages are pressurized with CO 2. In an attempt to produce another bubbly soda beverage, an intrepid chemist attempted to use three other gases: He, N 2, and Xe. Rank the four beverages in order of how fast the drink would go "flat" and explain your reasoning. Which beverage would have the shortest shelf life (i. , how long will an unopened bottle still be good)? Explain your answer. ♦️ Urea is synthesized industrially by the reaction of ammonia and carbon dioxide to produce ammonium carbamate, followed by dehydration of ammonium carbamate to give urea and water. This process is shown in the following set of chemical equations:. Q: What are carbonated beverages pressurized with? Choices: - helium - dioxide - hydrogen - co2 A:
co2
