Q: A system of glands secretes what chemical messenger molecules into the blood? Read this paragraph and choose the correct option from the provided answers: system of glands that secrete chemical messenger molecules called hormones into the blood. Choices: - metabolytes - enzymes - acids - hormones A:
hormones

Q: Concentration is the removal of solvent, which increases the concentration of what? Read this paragraph and choose the correct option from the provided answers: Often, a worker will need to change the concentration of a solution by changing the amount of solvent. Dilution is the addition of solvent, which decreases the concentration of the solute in the solution. Concentration is the removal of solvent, which increases the concentration of the solute in the solution. (Do not confuse the two uses of the word concentration here!) In both dilution and concentration, the amount of solute stays the same. This gives us a way to calculate what the new solution volume must be for the desired concentration of solute. From the definition of molarity,. Choices: - vapor - sodium - Water - solute A:
solute

Q: Q: The tendency of an object to resist a change in its motion is called? Read this paragraph and choose the correct option from the provided answers: Inertia is the tendency of an object to resist a change in its motion. The inertia of an object depends on its mass. Objects with greater mass have greater inertia. To overcome inertia, an unbalanced force must be applied to an object. Choices: - gravitation - magnetism - friction - inertia A:
A: inertia

Question: Q: Some marine algae have evolved special structures capable of what plant process? Read this paragraph and choose the correct option from the provided answers: in color. Golden algae are found in both freshwater and marine environments, where they form a major part of the plankton community. The brown algae are primarily marine, multicellular organisms that are known colloquially as seaweeds. Giant kelps are a type of brown algae. Some brown algae have evolved specialized tissues that resemble terrestrial plants, with root-like holdfasts, stem-like stipes, and leaf-like blades that are capable of photosynthesis. The stipes of giant kelps are enormous, extending in some cases for 60 meters. A variety of algal life cycles exists, but the most complex is alternation of generations, in which both haploid and diploid stages involve multicellularity. Compare this life cycle to that of humans, for instance. Haploid gametes produced by meiosis (sperm and egg) combine in fertilization to generate a diploid zygote that undergoes many rounds of mitosis to produce a multicellular embryo and then a fetus. However, the individual sperm and egg themselves never become multicellular beings. Terrestrial plants also have evolved alternation of generations. In the brown algae genus Laminaria, haploid spores develop into multicellular gametophytes, which produce haploid gametes that combine to produce diploid organisms that then become multicellular organisms with a different structure from the haploid form (Figure 23.19). Certain other organisms perform alternation of generations in which both the haploid and diploid forms look the same. Choices: - pollination - respiration - seed germination - photosynthesis A:
Answer: photosynthesis

(Q).
Q: What determines the color of visible light? Read this paragraph and choose the correct option from the provided answers: Human beings and other primates also have the ability to see in color. We have special cells inside our eyes that can distinguish different wavelengths of visible light. Visible light is light in the range of wavelengths that the human eye can sense. The exact wavelength of visible light determines its color. Choices: - wavelength speed - wavelength density - molecular wavelength - exact wavelength A:
(A).
exact wavelength
