Answer the following question given this paragraph: Summary The concentration of a substance is the quantity of solute present in a given quantity of solution. Concentrations are usually expressed as molarity, the number of moles of solute in 1 L of solution. Solutions of known concentration can be prepared either by dissolving a known mass of solute in a solvent and diluting to a desired final volume or by diluting the appropriate volume of a more concentrated solution (a stock solution) to the desired final volume. Q: The concentration of a substance is the quantity of solute present in a given quantity of ___________? Choices: - structure - mixture - salutation - solution A:
solution

Answer the following question given this paragraph: People have probably wondered about the natural world for as long as there have been people. So it's no surprise that science has roots that go back thousands of years. Some of the earliest contributions to science were made by Greek philosophers more than two thousand years ago. It wasn't until many centuries later, however, that the scientific method and experimentation were introduced. The dawn of modern science occurred even more recently. It is generally traced back to the scientific revolution, which took place in Europe starting in the 1500s. Q: The scientific revolution took place where starting in the 1500s? Choices: - africa - south america - north america - europe A:
(A).
europe
Ques:Answer the following question given this paragraph: Most annelids can reproduce both asexually and sexually. Asexual reproduction may occur by budding or fission. Sexual reproduction varies by species. Some species go through a larval stage before developing into adults. Other species grow to adult size without going through a larval stage. Q: Budding and fission in annelids are examples of what type of reproduction? Choices: - byproduct - hybrid - sexual - asexual A:

Ans:asexual
Answer the following question given this paragraph: in a one-liter container (Figure 22.15). In this case, the force exerted by the movement of the gas molecules against the walls of the two-liter container is lower than the force exerted by the gas molecules in the one-liter container. Therefore, the pressure is lower in the two-liter container and higher in the one-liter container. At a constant temperature, changing the volume occupied by the gas changes the pressure, as does changing the number of gas molecules. Boyle's law describes the relationship between volume and pressure in a gas at a constant temperature. Boyle discovered that the pressure of a gas is inversely proportional to its volume: If volume increases, pressure decreases. Likewise, if volume decreases, pressure increases. Pressure and volume are inversely related (P = k/V). Therefore, the pressure in the one-liter container (one-half the volume of the two-liter container) would be twice the pressure in the two-liter container. Boyle's law is expressed by the following formula:. Q: Boyle discovered that what property of a gas is inversely proportional to its volume? Choices: - temperature - amount - mass - pressure A:
pressure
