Answer the following question given this paragraph: A food chain is a simple diagram that shows one way energy flows through an ecosystem. You can see an example of a food chain in Figure below . Producers form the base of all food chains. The consumers that eat producers are called primary consumers. The consumers that eat primary consumers are secondary consumers. This chain can continue to multiple levels. Q: What term is used to describe a simple diagram that shows one way energy flows through an ecosystem? Choices: - water cycle - food pyramid - fuel chain - food chain A:
food chain
Answer the following question given this paragraph: 9.4 | Translation By the end of this section, you will be able to: Describe the different steps in protein synthesis Discuss the role of ribosomes in protein synthesis Describe the genetic code and how the nucleotide sequence determines the amino acid and the protein sequence The synthesis of proteins is one of a cell's most energy-consuming metabolic processes. In turn, proteins account for more mass than any other component of living organisms (with the exception of water), and proteins perform a wide variety of the functions of a cell. The process of translation, or protein synthesis, involves decoding an mRNA message into a polypeptide product. Amino acids are covalently strung together in lengths ranging from approximately 50 amino acids to more than 1,000. Q: With the exception of water, what accounts for more mass than any other component of living organisms? Choices: - hormones - nervous tissue - fats - proteins A:
proteins
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: PV = nRT This equation is known as the ideal gas law. An ideal gas is defined as a hypothetical gaseous substance whose behavior is independent of attractive and repulsive forces and can be completely described by the ideal gas law. In reality, there is no such thing as an ideal gas, but an ideal gas is a useful conceptual model that allows us to understand how gases respond to changing conditions. As we shall see, under many conditions, most real gases exhibit behavior that closely approximates that of an ideal gas. The ideal gas law can therefore be used to predict the behavior of real gases under most conditions. As you will learn in Section 10.8 "The Behavior of Real Gases", the ideal gas law does not work well at very low temperatures or very high pressures, where deviations from ideal behavior are most commonly observed. Q: The important equation pv = nrt holds true for substances in what state of matter? Choices: - solids - liquids - products - gas A:
Answer: gas

Answer the following question given this paragraph: Overharvesting Overharvesting is a serious threat to many species, but particularly to aquatic species. There are many examples of regulated fisheries (including hunting of marine mammals and harvesting of crustaceans and other species) monitored by fisheries. Q: Overharvesting is a serious threat particularly to which species? Choices: - aerial species - amphibious species - terrestrial species - aquatic species A:
**Answer**
aquatic species
