Q: In the case of a light bulb, electricity is converted to light and what kind of energy? Read this paragraph and choose the correct option from the provided answers: Most circuits have devices such as light bulbs that convert electric energy to other forms of energy. In the case of a light bulb, electricity is converted to light and thermal energy. Choices: - nuclear - abstract - chemical - thermal A:
thermal

Q: As the prokaryotic cell size increases, what happens to its surface area-to-volume ratio? Read this paragraph and choose the correct option from the provided answers: 4.2 Prokaryotic Cells Prokaryotes are predominantly single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, and DNA that is not membrane-bound. Most have peptidoglycan cell walls and many have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1 to 5.0 m. As a cell increases in size, its surface area-to-volume ratio decreases. If the cell grows too large, the plasma membrane will not have sufficient surface area to support the rate of diffusion required for the increased volume. Choices: - stagnates - halts - increases - decreases A:
(Answer)
decreases

Ques: Q: What element do nuclear power plants use in fuel rods? Read this paragraph and choose the correct option from the provided answers: Nuclear power plants use uranium in fuel rods. The fuel rods become nuclear waste. Nuclear waste can be dangerous for hundreds of thousands of years. Choices: - plutonium - boron - magnesium - uranium A:
Ans: uranium

(Q).
Q: What bonds form because they give atoms a more stable arrangement of electrons? Read this paragraph and choose the correct option from the provided answers: Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the hydrogen atoms in Figure above . Alone, each hydrogen atom has just one electron. By sharing electrons with another hydrogen atom, it has two electrons: its own and the one in the other hydrogen atom. The shared electrons are attracted to both hydrogen nuclei. This force of attraction holds the two atoms together as a molecule of hydrogen. Choices: - Hydrogen bond - Ionic bond - Polar bond - covalent A:
(A).
covalent

Ques:Q: What is the most useful quantity for counting particles? Read this paragraph and choose the correct option from the provided answers: The most useful quantity for counting particles is the mole. So if each coefficient is multiplied by a mole, the balanced chemical equation tells us that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This is the conventional way to interpret any balanced chemical equation. Choices: - the coefficient - the periodic table - the vector - the mole A:

Ans:the mole

Q: A cartilaginous joint where the bones are joined by fibrocartilage is called a what? Read this paragraph and choose the correct option from the provided answers: Symphysis A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis ("growing together"). Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. This gives symphyses the ability to strongly unite the adjacent bones, but can still allow for limited movement to occur. Thus, a symphysis is functionally classified as an amphiarthrosis. The gap separating the bones at a symphysis may be narrow or wide. Examples in which the gap between the bones is narrow include the pubic symphysis and the manubriosternal joint. At the pubic symphysis, the pubic portions of the right and left hip bones of the pelvis are joined together by fibrocartilage across a narrow gap. Similarly, at the manubriosternal joint, fibrocartilage unites the manubrium and body portions of the sternum. The intervertebral symphysis is a wide symphysis located between the bodies of adjacent vertebrae of the vertebral column. Here a thick pad of fibrocartilage called an intervertebral disc strongly unites the adjacent vertebrae by filling the gap between them. The width of the intervertebral symphysis is important because it allows for small movements between the adjacent vertebrae. In addition, the thick intervertebral disc provides cushioning between the vertebrae, which is important when carrying heavy objects or during high-impact activities such as running or jumping. Choices: - vesicles - mitosis - Testes - symphysis A:
symphysis
