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:
steroids
Answer the following question given this paragraph: Note Organic and biochemical equations are frequently written showing only the organic reactants and products. In this way, we focus attention on the organic starting material and product, rather than on balancing complicated equations. Ethanol is oxidized in the liver to acetaldehyde:. Q: Organic and biochemical equations show the initial and final products of the equation, respectively known as the reactants and what else? Choices: - consumers - dividends - reactors - products A:
products
Q: Answer the following question given this paragraph: Non-steroid hormones are made of amino acids. They are not fat soluble, so they cannot diffuse across the plasma membrane of target cells. Instead, a non-steroid hormone binds to a receptor on the cell membrane (see Figure below ). The binding of the hormone triggers an enzyme inside the cell membrane. The enzyme activates another molecule, called the second messenger, which influences processes inside the cell. Most endocrine hormones are non-steroid hormones, including insulin and thyroid hormones. Q: What are non-steroid hormones made of? Choices: - proteins - Molecules - fats - amino acids A:
A: amino acids
Question: Answer the following question given this paragraph: the net torque is the vector sum of all the torques acting on the object. When adding torques it is necessary to subtract CW from CCW torques. Q: The vector sum of all the torques acting on an object is called what? Choices: - peak capacity - torque load - homeostasis - net torque A:
Answer: net torque

Answer the following question given this paragraph: Different types of plant cells include parenchymal, collenchymal, and sclerenchymal cells. The three types differ in structure and function. Q: Parenchymal, collenchymal, and sclerenchymal cells are associated with what types of living things? Choices: - primates - parasites - fungi - plants A:
**Answer**
plants
Q: Answer the following question given this paragraph: A point mutation is a change in a single nucleotide in DNA. This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations, as shown in Table below . The effects of point mutations depend on how they change the genetic code. You can watch an animation about nonsense mutations at this link: http://www. biostudio. com/d_%20Nonsense%20Suppression%20I%20Nonsense%20Mutation. htm . Q: What is the name for a change in a single nucleotide in dna? Choices: - adaptation - spontaneous mutation - cell regeneration - point mutation A:
A: point mutation
