input with options: Answer the following question given this paragraph: Positive Feedback Positive feedback intensifies a change in the body's physiological condition rather than reversing it. A deviation from the normal range results in more change, and the system moves farther away from the normal range. Positive feedback in the body is normal only when there is a definite end point. Childbirth and the body's response to blood loss are two examples of positive feedback loops that are normal but are activated only when needed. Childbirth at full term is an example of a situation in which the maintenance of the existing body state is not desired. Enormous changes in the mother's body are required to expel the baby at the end of pregnancy. And the events of childbirth, once begun, must progress rapidly to a conclusion or the life of the mother and the baby are at risk. The extreme muscular work of labor and delivery are the result of a positive feedback system (Figure 1.11). Q: What type of feedback intensifies a change in the body's physiological condition rather than reversing it? A:
OPTIONS:
- negative feedback
- neutral feedback
- susceptible feedback
- positive feedback
output: positive feedback

Q: Answer the following question given this paragraph: Forces between Molecules Under appropriate conditions, the attractions between all gas molecules will cause them to form liquids or solids. This is due to intermolecular forces, not intramolecular forces. Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 10.5 illustrates these different molecular forces. The strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule. For example, to overcome the IMFs in one mole of liquid HCl and convert it into gaseous HCl requires only about 17 kilojoules. However, to break the covalent bonds between the hydrogen and chlorine atoms in one mole of HCl requires about 25 times more energy430 kilojoules. Q: Under appropriate conditions, the attractions between all molecules in what state will cause them to form liquids or solids? A:

OPTIONS:
- soild
- plasma
- liquid
- gas

A: gas

input: OPTIONS:
- destroys all viruses
- reprograms viruses
- enhances cells
- inhibits spread of virus Now, answer this question: Answer the following question given this paragraph: an enzyme (viral neuraminidase) that allows new virions to leave their infected cells. Thus, Tamiflu inhibits the spread of virus from infected to uninfected cells. Other antiviral drugs, such as Ribavirin, have been used to treat a variety of viral infections, although its mechanism of action against certain viruses remains unclear. Q: What effect does tamiflu have on viruses and cells? A:
A:
output: inhibits spread of virus

Answer the following question given this paragraph: Momentum is a vector that points in the direction of the velocity vector. The magnitude of this vector is the product of mass and speed. Q: The magnitude of the momentum vector is the product of what two properties? A:

OPTIONS:
- acceleration and speed
- work and speed
- volume and speed
- mass and speed

Answer: mass and speed

Problem: OPTIONS:
- gases
- complex
- liquids
- crystalline
Q: Answer the following question given this paragraph: The majority of solids are crystalline in nature. A crystal is a substance in which the particles are arranged in an orderly, repeating, three-dimensional pattern. Particles of a solid crystal may be ions, atoms, or molecules, depending on the type of substance. The three-dimensional arrangement of a solid crystal is referred to as the crystal lattice . Different arrangements of the particles within a crystal cause them to adopt several different shapes. Q: The majority of solids are what in nature? A:
Answer: crystalline

Answer the following question given this paragraph: The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane. Such cells are typically found lining the small intestine, the organ that absorbs nutrients from digested food. This is an excellent example of form matching the function of a structure. People with celiac disease have an immune response to gluten, which is a protein found in wheat, barley, and rye. The immune response damages microvilli, and thus, afflicted individuals cannot absorb nutrients. This leads to malnutrition, cramping, and diarrhea. Patients suffering from celiac disease must follow a gluten-free diet. Q: People with celiac disease have an immune response to what, which ultimately leads to malnutrition, cramping, and diarrhea? A:

OPTIONS:
- fish
- lactose
- seeds
- gluten

Answer:
gluten
