Answer the following question given this paragraph: Q: Because plants are relatively immobile, they can function with bulky energy storage in the form of what? Choices: - fat - protein - dioxide - starch A:
starch
Answer the following question given this paragraph: Q: What "plumbing" structures inside the veins maintain a unidirectional flow of blood despite the low blood pressure? Choices: - funnels - tubes - pumps - valves A:
valves
Q: Answer the following question given this paragraph: Triglycerides function as a long-term storage form of energy in the human body. Because of the long carbon chains, triglycerides are nearly nonpolar molecules and thus do not dissolve readily in polar solvents such as water. Instead, oils and fats are soluble in nonpolar organic solvents such as hexane and ethers. Q: What substances function as a long-term energy store in the human body and possess long carbon chains that prevent dissolving in water? Choices: - hydrocarbons - steroids - nanoparticles - triglycerides A:
A: triglycerides
Question: Answer the following question given this paragraph: Parts of the Digestive System The vertebrate digestive system is designed to facilitate the transformation of food matter into the nutrient components that sustain organisms. Oral Cavity The oral cavity, or mouth, is the point of entry of food into the digestive system, illustrated in Figure 34.9. The food consumed is broken into smaller particles by mastication, the chewing action of the teeth. All mammals have teeth and can chew their food. The extensive chemical process of digestion begins in the mouth. As food is being chewed, saliva, produced by the salivary glands, mixes with the food. Saliva is a watery substance produced in the mouths of many animals. There are three major glands that secrete salivathe parotid, the submandibular, and the sublingual. Saliva contains mucus that moistens food and buffers the pH of the food. Saliva also contains immunoglobulins and lysozymes, which have antibacterial action to reduce tooth decay by inhibiting growth of some bacteria. Saliva also contains an enzyme called salivary amylase that begins the. Q: What system is designed to facilitate the transformation of food matter into the nutrient components that sustain organisms? Choices: - tissue - skeletal - respiratory - digestive A:
Answer: digestive

Answer the following question given this paragraph: Mineralocorticoids Mineralocorticoids are hormones synthesized by the adrenal cortex that affect osmotic balance. Aldosterone is a mineralocorticoid that regulates sodium levels in the blood. Almost all of the sodium in the blood is reclaimed by the renal tubules under the influence of aldosterone. Because sodium is always reabsorbed by active transport and water follows sodium to maintain osmotic balance, aldosterone manages not only sodium levels but also the water levels in body fluids. In contrast, the aldosterone also stimulates potassium secretion concurrently with sodium reabsorption. In contrast, absence of aldosterone means that no sodium gets reabsorbed in the renal tubules and all of it gets excreted in the urine. In addition, the daily dietary potassium load is not secreted and the retention of K+ can cause a dangerous increase in plasma K+ concentration. Patients who have Addison's disease have a failing adrenal cortex and cannot produce aldosterone. They lose sodium in their urine constantly, and if the supply is not replenished, the consequences can be fatal. Q: Mineralocorticoids are hormones synthesized by the adrenal cortex that affect what balance, by regulating sodium and water levels? Choices: - blood pressure - homeostasis - equilibrium - osmotic A:
**Answer**
osmotic
