Answer the following question given this paragraph: Oxygen is just one substance transported by the blood. The blood also transports nutrients such as glucose. Q: Both oxygen and glucose are transported within the body via what? Choices: - bone - heart - marrow - blood A:
blood
Answer the following question given this paragraph: Some materials have negative heats of solution; the dissolution of one of these solutes in water is an exothermic process. Heat is released, causing a net increase in the temperature of the solution. Conversely, other substances have positive heats of solution. For example, the dissolution of potassium nitrate in water is an endothermic process. The resulting absorption of energy causes the solution to become colder. Calculations involving heats of solutions follow the same basic approach that we have used with other enthalpy problems. Q: Some materials have negative heats of solution; the dissolution of one of these solutes in water is called? Choices: - endothermic process - acetylene process - ionized process - exothermic process A:
exothermic process
Q: Answer the following question given this paragraph: Cardiac muscle is found only in the walls of the heart. When cardiac muscle contracts, the heart beats and pumps blood. Cardiac muscle contains a great many mitochondria, which produce ATP for energy. This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary like those of smooth muscle. Q: What muscle is found only in the walls of the heart? Choices: - respiratory muscle - abdominal muscle - skeletal muscle - cardiac muscle A:
A: cardiac muscle
Question: Answer the following question given this paragraph: Several lines of evidence support that chlorarachniophytes evolved from secondary endosymbiosis. The chloroplasts contained within the green algal endosymbionts still are capable of photosynthesis, making chlorarachniophytes photosynthetic. The green algal endosymbiont also exhibits a stunted vestigial nucleus. In fact, it appears that chlorarachniophytes are the products of an evolutionarily recent secondary endosymbiotic event. The plastids of chlorarachniophytes are surrounded by four membranes: The first two correspond to the inner and outer membranes of the photosynthetic cyanobacterium, the third corresponds to the green alga, and the fourth corresponds to the vacuole that surrounded the green alga when it was engulfed by the chlorarachniophyte ancestor. In other lineages that involved secondary endosymbiosis, only three membranes can be identified around plastids. This is currently rectified as a sequential loss of a membrane during the course of evolution. The process of secondary endosymbiosis is not unique to chlorarachniophytes. In fact, secondary endosymbiosis of green algae also led to euglenid protists, whereas secondary endosymbiosis of red algae led to the evolution of dinoflagellates, apicomplexans, and stramenopiles. Q: The chloroplasts contained within the green algal endosymbionts still are capable of what process associated with plants? Choices: - germination - respiration - reproduction - photosynthesis A:
Answer: photosynthesis
