Q: Some plants have stolons, or stems, that run along the ground and are commonly called what? Read this paragraph and choose the correct option from the provided answers: Figure 32.25 A stolon, or runner, is a stem that runs along the ground. At the nodes, it forms adventitious roots and buds that grow into a new plant. Choices: - stages - shoots - roots - runners A:
runners

Q: The temperature dependence of solubility can be exploited to prepare what solutions of certain compounds? Read this paragraph and choose the correct option from the provided answers: The temperature dependence of solubility can be exploited to prepare supersaturated solutions of certain compounds. A solution may be saturated with the compound at an elevated temperature (where the solute is more soluble) and subsequently cooled to a lower temperature without precipitating the solute. The resultant solution contains solute at a concentration greater than its equilibrium solubility at the lower temperature (i. , it is supersaturated) and is relatively stable. Precipitation of the excess solute can be initiated by adding a seed crystal (see the video in the Link to Learning earlier in this module) or by mechanically agitating the solution. Some hand warmers, such as the one pictured in Figure 11.18, take advantage of this behavior. Choices: - mineralized - isolated - instantiated - supersaturated A:
(Answer)
supersaturated

Ques: Q: The work-energy theorem states that the net work on a system equals the change in what type of energy? Read this paragraph and choose the correct option from the provided answers: How the Work-Energy Theorem Applies Now let us consider what form the work-energy theorem takes when both conservative and nonconservative forces act. We will see that the work done by nonconservative forces equals the change in the mechanical energy of a system. As noted in Kinetic Energy and the Work-Energy Theorem, the work-energy theorem states that the net work on a system equals the change in its kinetic energy, or W net = KE . The net work is the sum of the work by nonconservative forces plus the work by conservative forces. That is,. Choices: - binary energy - new energy - residual energy - kinetic energy A:
Ans: kinetic energy

Q: The anterior pituitary produces seven different what, each with a special function? Read this paragraph and choose the correct option from the provided answers: Anterior Pituitary The anterior pituitary gland, or adenohypophysis, is surrounded by a capillary network that extends from the hypothalamus, down along the infundibulum, and to the anterior pituitary. This capillary network is a part of the hypophyseal portal system that carries substances from the hypothalamus to the anterior pituitary and hormones from the anterior pituitary into the circulatory system. A portal system carries blood from one capillary network to another; therefore, the hypophyseal portal system allows hormones produced by the hypothalamus to be carried directly to the anterior pituitary without first entering the circulatory system. The anterior pituitary produces seven hormones: growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH), melanin-stimulating hormone (MSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Anterior pituitary hormones are sometimes referred to as tropic hormones, because they. Choices: - neurotransmitters - proteins - enzymes - hormones A:
(A).
hormones

Ques:Q: How does the atomic number change during beta emission? Read this paragraph and choose the correct option from the provided answers: Beta () decay is a more complicated process. Unlike the -emission, which simply expels a particle, the -emission involves the transformation of a neutron in the nucleus to a proton and an electron. The electron is then ejected from the nucleus. In the process, the atomic number increases by one while the atomic weight stays the same. As is the case with -emissions, -emissions are often accompanied by -radiation. Choices: - stays the same - increases by two - decreases by one - increases by one A:

Ans:increases by one

Ques:Q: What state of matter is like a liquid in that particles are in contact with each other, but unlike liquids in that the intermolecular forces are strong enough to hold the particles in place? Read this paragraph and choose the correct option from the provided answers: A solid is like a liquid in that particles are in contact with each other. Solids are unlike liquids in that the intermolecular forces are strong enough to hold the particles in place. At low enough temperatures, all substances are solids (helium is the lone exception), but the temperature at which the solid state becomes the stable phase varies widely among substances, from 20 K (253C) for hydrogen to over 3,900 K (3,600C) for carbon. The solid phase has several characteristics. First, solids maintain their shape. They do not fill their entire containers like gases do, and they do not adopt the shape of their containers like liquids do. They cannot be easily compressed like gases can, and they have relatively high densities. Solids may also demonstrate a variety of properties. For example, many metals can be beaten into thin sheets or drawn into wires, while compounds such as NaCl will shatter if they are struck. Some metals, such as sodium and potassium, are rather soft, while others, such as diamond, are very hard and can easily scratch other substances. Appearances differ as well: most metals are shiny and silvery, but sulfur (a nonmetal) is yellow, and ionic compounds can take on a rainbow of colors. Solid metals conduct electricity and heat, while ionic solids do not. Many solids are opaque, but some are transparent. Some dissolve in water, but some do not. Figure 10.13 "Properties of Solids" shows two solids that exemplify the similar and dissimilar properties of solids. Figure 10.13 Properties of Solids. Choices: - plasmas - gases - fluids - solids A:

Ans:
solids
