Answer the following question given this paragraph: Liquids have a definite volume, but no definite shape. A gallon of milk will keep the same volume whether it is stored in a one-gallon milk jug or a ten-gallon barrel. The volume is the same, but the fluid will either fill the jug or spread out over the bottom of the barrel. Q: What state of matter has a definite volume, but not a definite shape? Choices: - gas - solid - mixture - liquid A:
(Answer)
liquid
Ques: Answer the following question given this paragraph: Steroid Hormones The primary hormones derived from lipids are steroids. Steroid hormones are derived from the lipid cholesterol. For example, the reproductive hormones testosterone and the estrogenswhich are produced by the gonads (testes and ovaries)are steroid hormones. The adrenal glands produce the steroid hormone aldosterone, which is involved in osmoregulation, and cortisol, which plays a role in metabolism. Like cholesterol, steroid hormones are not soluble in water (they are hydrophobic). Because blood is water-based, lipidderived hormones must travel to their target cell bound to a transport protein. This more complex structure extends the half-life of steroid hormones much longer than that of hormones derived from amino acids. A hormone's half-life is the time required for half the concentration of the hormone to be degraded. For example, the lipid-derived hormone cortisol has a half-life of approximately 60 to 90 minutes. In contrast, the amino acidderived hormone epinephrine has a half-life of approximately one minute. Q: The primary hormones derived from lipids are what? Choices: - amino acids - melatonins - antibiotics - steroids A:
Ans: steroids

Ans:cubes
Ques:Answer the following question given this paragraph: If a solute is a solid or liquid, increasing the temperature increases its solubility. For example, more sugar can dissolve in hot water than in cold water. Q: What does increasing a solute's temperature do? Choices: - increases its viscosity - decrease its solubility - no change - increases its solubility A:

Ans:
increases its solubility
