Ques: Q: The head, thorax, and abdomen comprise what type of body structure, possessed by arthropods? Read this paragraph and choose the correct option from the provided answers: Arthropods range in length from about 1 millimeter (0.04 inches) to 4 meters (about 13 feet). They have a segmented body with a hard exoskeleton. They also have jointed appendages. The body segments are the head, thorax, and abdomen (see Figure below ). In some arthropods, the head and thorax are joined together as a cephalothorax. Choices: - vertebrate - elongated - permeable - segmented A:
Ans: segmented

Ques: Q: What is another name for a radioactive isotope? Read this paragraph and choose the correct option from the provided answers: A radioactive isotope, or radioisotope, has atoms with unstable nuclei. The unstable nuclei naturally decay, or break down, by losing energy and particles of matter to become more stable. If they gain or lose protons as they decay, they become different elements. Over time, as the nuclei continue to decay, less and less of the original radioisotope remains. Choices: - nono particle - kilocalorie - xerophyte - radiostope A:
Ans: radiostope

Ques: Q: What are fungus-like protists? Read this paragraph and choose the correct option from the provided answers: Fungus-like protists are molds . They are absorptive feeders on decaying organic matter. They resemble fungi, and they reproduce with spores as fungi do. However, in other ways, they are quite different from fungi and more like other protists. For example, they have cell walls made of cellulose , whereas fungi have cell walls made of chitin. Like other protists, they have complicated life cycles with both asexual and sexual reproduction. They are motile during some stages of their life cycle. Two major types of fungus-like protists are slime molds and water molds. Choices: - feces - viruses - bacteria - molds A:
Ans: molds

Ques: Q: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at this? Read this paragraph and choose the correct option from the provided answers: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. Ecell = Ecathode Eanode +0.34 V = E 2+ EH + /H = E 2+ 0 = E Cu. Choices: - Spinner - plasma - electrode - cathode A:
Ans:
cathode
