Q: In plants, pigment molecules absorb only visible light for photosynthesis. the visible light seen by humans as white light actually exists in a what? Read this paragraph and choose the correct option from the provided answers: Absorption of Light Light energy enters the process of photosynthesis when pigments absorb the light. In plants, pigment molecules absorb only visible light for photosynthesis. The visible light seen by humans as white light actually exists in a rainbow of colors. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colors to the human eye. The visible light portion of the electromagnetic spectrum is perceived by the human eye as a rainbow of colors, with violet and blue having shorter wavelengths and, therefore, higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy. Choices: - vacuum - transparency - invisible spectrum - rainbow of colors A:
rainbow of colors

Q: What are ionic substances completely held together by? Read this paragraph and choose the correct option from the provided answers: Ionic substances are completely held together by ionic bonds. The full charges of the ions (for example, Na + and Cl - in sodium chloride) cause electrostatic interactions that result in a stable crystal lattice. We saw in the previous chapter that most ionic compounds have high melting points, are brittle, are often soluble in water, and conduct electricity when melted or dissolved in water. Ionic compounds exist as extended, orderly arrangements of ions. As we will see, this is quite different from the structure of molecular substances, which take the form of collections of individual molecules. The atoms within a molecule are held very strongly together, but the interactions between different molecules are significantly weaker. Choices: - thermal bonds - localized bonds - magnetic bonds - ionic bonds A:
ionic bonds

Q: Q: Latitude, humidity, and elevation affect the type of what, a term for a large naturally occurring community? Read this paragraph and choose the correct option from the provided answers: Factors affecting biome type include latitude, humidity, and elevation. Choices: - territory - ecosystem - climate - biome A:
A: biome

Question: Q: The primary application of biotechnology is in what field? Read this paragraph and choose the correct option from the provided answers: 10.1 | Cloning and Genetic Engineering By the end of this section, you will be able to: Explain the basic techniques used to manipulate genetic material Explain molecular and reproductive cloning Biotechnology is the use of artificial methods to modify the genetic material of living organisms or cells to produce novel compounds or to perform new functions. Biotechnology has been used for improving livestock and crops since the beginning of agriculture through selective breeding. Since the discovery of the structure of DNA in 1953, and particularly since the development of tools and methods to manipulate DNA in the 1970s, biotechnology has become synonymous with the manipulation of organisms' DNA at the molecular level. The primary applications of this technology are in medicine (for the production of vaccines and antibiotics) and in agriculture (for the genetic modification of crops). Biotechnology also has many industrial applications, such as fermentation, the treatment of oil spills, and the production of biofuels, as well as many household applications such as the use of enzymes in laundry detergent. Choices: - physics - chemistry - psychology - medicine A:
Answer: medicine

*Question*
Q: What kind of bases completely dissociate in water, releasing all hydroxide anions into the solution? Read this paragraph and choose the correct option from the provided answers: Strong bases completely dissociate in water, releasing all hydroxide anions into the solution. The most common strong bases are soluble metal hydroxides. Weak bases partially deprotonate water to form small amounts of hydroxide and the protonated base. Choices: - unusual - weak - whole - strong A:
**Answer**
strong

*Question*
Q: What is root that does not arise from a usual place? Read this paragraph and choose the correct option from the provided answers: the radicle is also growing and producing the primary root. As it grows downward to form the tap root, lateral roots branch off to all sides, producing the typical dicot tap root system. In monocot seeds (Figure 32.21), the testa and tegmen of the seed coat are fused. As the seed germinates, the primary root emerges, protected by the root-tip covering: the coleorhiza. Next, the primary shoot emerges, protected by the coleoptile: the covering of the shoot tip. Upon exposure to light (i. when the plumule has exited the soil and the protective coleoptile is no longer needed), elongation of the coleoptile ceases and the leaves expand and unfold. At the other end of the embryonic axis, the primary root soon dies, while other, adventitious roots (roots that do not arise from the usual place i. the root) emerge from the base of the stem. This gives the monocot a fibrous root system. Choices: - momentous - monomers - hypochlorous - adventitious A:
**Answer**
adventitious
