Question: Q: What do you call the separation of ions that occurs when a solid ionic compound dissolves? Read this paragraph and choose the correct option from the provided answers: An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds. The subscripts for the ions in the chemical formulas become the coefficients of the respective ions on the product side of the equation. Shown below are dissociation equations for NaCl, Ca(NO 3 ) 2 , and (NH 4 ) 3 PO 4 . Choices: - deformation - decomposition - dissolution - dissociation A:
Answer: dissociation

Question: Q: What are the special mating behaviors in birds called? Read this paragraph and choose the correct option from the provided answers: Birds reproduce sexually and have separates sexes. Fertilization occurs internally, so males and females must mate. Many bird species have special behaviors, such as unique songs or visual displays, for attracting mates. These special behaviors are called courtship. The white peacock in Figure below is putting on a stunning display of his amazing tail feathers to court a mate. Choices: - display - attraction - presentation - courtship A:
Answer: courtship

Question: Q: Peroxisomes perform a couple of different functions, including lipid metabolism and chemical detoxification. in contrast to the digestive enzymes found in lysosomes, the enzymes within peroxisomes serve to transfer hydrogen atoms from various molecules to oxygen, producing what? Read this paragraph and choose the correct option from the provided answers: Peroxisomes Like lysosomes, a peroxisome is a membrane-bound cellular organelle that contains mostly enzymes (Figure 3.17). Peroxisomes perform a couple of different functions, including lipid metabolism and chemical detoxification. In contrast to the digestive enzymes found in lysosomes, the enzymes within peroxisomes serve to transfer hydrogen atoms from various molecules to oxygen, producing hydrogen peroxide (H2O2). In this way, peroxisomes neutralize poisons such as alcohol. In order to appreciate the importance of peroxisomes, it is necessary to understand the concept of reactive oxygen species. Choices: - calcium - water - hydrogen - hydrogen peroxide A:
Answer:
hydrogen peroxide
