Answer the following question given this paragraph: In the lungs, oxygen diffuses out of the alveoli and into the capillaries surrounding the alveoli. Oxygen (about 98 percent) binds reversibly to the respiratory pigment hemoglobin found in red blood cells (RBCs). RBCs carry oxygen to the tissues where oxygen dissociates from the hemoglobin and diffuses into the cells of the tissues. More specifically, alveolar P O 2. Q: In the lungs, oxygen diffuses out of the alveoli and into where? Choices: - blood - neurons - cillia - capillaries A:
capillaries

Answer the following question given this paragraph: Q: What structures on the gastrodermal cells keep the contents of the gastrovascular cavity agitated and help distribute nutrients? Choices: - telomeres - sporangia - nucleus - flagella A:
(Answer)
flagella
Ques: Answer the following question given this paragraph: Soaps and Detergents Pioneers made soap by boiling fats with a strongly basic solution made by leaching potassium carbonate, K2CO3, from wood ashes with hot water. Animal fats contain polyesters of fatty acids (long-chain carboxylic acids). When animal fats are treated with a base like potassium carbonate or sodium hydroxide, glycerol and salts of fatty acids such as palmitic, oleic, and stearic acid are formed. The salts of fatty acids are called soaps. The sodium salt of stearic acid, sodium stearate, has the formula C17H35CO2Na and contains an uncharged nonpolar hydrocarbon chain, the C17H35 unit, and an ionic carboxylate group, the CO 2 unit (Figure 11.32). Q: What are the salts of fatty acids called? Choices: - dyes - creams - malts - soaps A:
Ans: soaps
(Q).
Answer the following question given this paragraph: Q: The infection-fighting complement system consists of roughly 30 proteins in? Choices: - stomach acid - stool - fats - blood plasma A:
(A).
blood plasma
Ques:Answer the following question given this paragraph: Starches are complex carbohydrates. They are polymers of glucose. Starches contain hundreds of glucose monomers. Plants make starches to store extra glucose. Consumers can get starches by eating plants. Common sources of starches in the human diet are pictured Figure below . Our digestive system breaks down starches to sugar, which our cells use for energy. Like other animals, we store any extra glucose as the complex carbohydrate called glycogen. Glycogen is also a polymer of glucose. Q: What do plants make to store extra glucose? Choices: - water - fats - sugars - starches A:

Ans:starches
Answer the following question given this paragraph: RNA consists of just one chain of nucleotides. DNA consists of two chains. Nitrogen bases on the two chains of DNA form hydrogen bonds with each other. Hydrogen bonds are relatively weak bonds that form between a positively charged hydrogen atom in one molecule and a negatively charged atom in another molecule. Hydrogen bonds form only between adenine and thymine, and between guanine and cytosine. These bonds hold the two chains together and give DNA is characteristic double helix, or spiral, shape. Q: What has two chains of nucleotides, one more than rna? Choices: - gna - fna - mna - dna A:
dna
