Answer the following question given this paragraph: Red blood cells transport oxygen to the tissues so they can function. In the absence of oxygen, cells cannot carry out their biochemical responsibilities. Oxygen moves to the cells attached to hemoglobin, a protein found in the red cells. In cases of carbon monoxide poisoning, CO binds much more strongly to the hemoglobin, blocking oxygen attachment and lowering the amount of oxygen reaching the cells. Treatment involves the patient breathing pure oxygen to displace the carbon monoxide. The equilibrium reaction shown below illustrates the shift toward the right when excess oxygen is added to the system:. Q: What type of blood cells transport oxygen to the tissues so they can function? Choices: - white blood cells - mutated blood cells - depleted blood cells - red blood cells A:
red blood cells

Answer the following question given this paragraph: All living organisms must have the ability to reproduce. Living things make more organisms like themselves. Whether the organism is a rabbit, or a tree, or a bacterium, life will create more life. If a species cannot create the next generation, the species will go extinct. Reproduction is the process of making the next generation and may be a sexual or an asexual process. Sexual reproduction involves two parents and the fusion of gametes , haploid sex cells from each parent. Sexual reproduction produces offspring that are genetically unique and increases genetic variation within a species. Asexual reproduction involves only one parent. It occurs without a fusion of gametes and produces offspring that are all genetically identical to the parent. Q: All living organisms must have what ability, in order to make more organisms like themselves? Choices: - absorption - cloning - variation - reproduction A:
(Answer)
reproduction
Ques: Answer the following question given this paragraph: Q: The vertebrate circulatory system enables blood to deliver ________ and remove wastes throughout the body. Choices: - hydrogen and nutrients - acid and nutrients - fluid and nutrients - oxygen and nutrients A:
Ans: oxygen and nutrients
(Q).
Answer the following question given this paragraph: The two major types of seed plants are the gymnosperms (seeds in cones) and angiosperms (seeds in ovaries of flowers). Figure below shows how the seeds of gymnosperms and angiosperms differ. Do you see the main difference between the two seeds? The angiosperm seed is surrounded by an ovary . Q: What are the two major types of seed plants called? Choices: - perennials and annuals - flowers and fruits - deciduous and evergreen - gymnosperms and angiosperms A:
(A).
gymnosperms and angiosperms
Ques:Answer the following question given this paragraph: As we saw in the previous chapter, ions are formed when atoms gain or lose electrons. If an atom loses one or more electrons, the resulting ion has a positive charge (more protons are present than electrons). If the atom gains one or more electrons, the resulting ion has a negative charge (more electrons are present than protons). Positive ions are called cations, and negative ions are called anions. Because opposite charges attract one another, cations and anions are held together by strong electromagnetic forces. An ionic compound consists of a large three-dimensional array of alternating cations and anions. For example, sodium chloride (NaCl) is composed of Na + and Cl - ions arranged into a structure like the one shown in Figure below . Q: When atoms gain or lose electrons, what is formed? Choices: - crystals - molecules - gas - ions A:

Ans:ions
Answer the following question given this paragraph: A metallic bond is the force of attraction between a positive metal ion and the valence electrons that surround itboth its own valence electrons and those of other ions of the same metal. The ions and electrons form a lattice-like structure. Only metals, such as the copper pictured in the Figure below , form metallic bonds. Q: What is the force of attraction between a positive metal ion and valence electrons? Choices: - liquid bond - covalent bond - galactic bond - metallic bond A:
metallic bond
