Answer the following question given this paragraph: Sources of voltage include electric generators and cells. Electric generators change kinetic energy to electrical energy. Chemical cells change chemical energy to electrical energy, and solar cells change solar energy to electrical energy. Q: Electric generators change kinetic energy to what type of energy? Choices: - thermal - light - intrinsic - electrical A:
electrical

(Answer)
ovary
Ques: Answer the following question given this paragraph: Electrons fill orbitals in a consistent order: they first fill the orbitals closest to the nucleus, then they continue to fill orbitals of increasing energy further from the nucleus. If there are multiple orbitals of equal energy, they will be filled with one electron in each energy level before a second electron is added. The electrons of the outermost energy level determine the energetic stability of the atom and its tendency to form chemical bonds with other atoms to form molecules. Under standard conditions, atoms fill the inner shells first, often resulting in a variable number of electrons in the outermost shell. The innermost shell has a maximum of two electrons but the next two electron shells can each have a maximum of eight electrons. This is known as the octet rule, which states, with the exception of the innermost shell, that atoms are more stable energetically when they have eight electrons in their valence shell, the outermost electron shell. Examples of some neutral atoms and their electron configurations are shown in Figure 2.7. Notice that in this Figure 2.7, helium has a complete outer electron shell, with two electrons filling its first and only shell. Similarly, neon has a complete outer 2n shell containing eight electrons. In contrast, chlorine and sodium have seven and one in their outer shells, respectively, but theoretically they would be more energetically stable if they followed the octet rule and had eight. Q: Which orbitals do electrons fill first? Choices: - empty orbitals - charged orbitals - furthest from nucleus - closest to the nucleus A:
Ans: closest to the nucleus

Answer the following question given this paragraph: Biochemical reactions are optimal at physiological temperatures. For example, most biochemical reactions work best at the normal body temperature of 98.6F (37C). Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates, and only when the temperature comes back to normal does the enzyme regain its shape and normal activity. Q: Biochemical reactions are optimal at physiological temperatures because many what lose function at lower and higher temperatures? Choices: - hormones - carbohydrates - neurons - enzymes A:
(A).
enzymes
Ques:Answer the following question given this paragraph: A habitat that is quickly being destroyed is the wetland . By the 1980s, over 80% of all wetlands in parts of the U. S. were destroyed. In Europe, many wetland species have gone extinct. For example, many bogs in Scotland have been lost because of human development. Q: Bog destruction in scotland is an example of the widespread loss of what kind of habitat? Choices: - tundra - ocean - desert - wetland A:

Ans:wetland
Question: Answer the following question given this paragraph: All plants have a characteristic life cycle that includes alternation of generations . Plants alternate between haploid and diploid generations. Alternation of generations allows for both asexual and sexual reproduction. Asexual reproduction with spores produces haploid individuals called gametophytes . Sexual reproduction with gametes and fertilization produces diploid individuals called sporophytes . A typical plant's life cycle is diagrammed in Figure below . Q: The plants alternation between haploid and diploud generations allow it to do what? Choices: - reproduce asexually and simultaneously - reproduce sexually and autonomously - reproduce asexually and biologically - reproduce asexually and sexually A:
Answer:
reproduce asexually and sexually
