Q: Answer the following question given this paragraph: Summary Superconductors are solids that at low temperatures exhibit zero resistance to the flow of electrical current, a phenomenon known as superconductivity. The temperature at which the electrical resistance of a substance drops to zero is itssuperconducting transition temperature (Tc). Superconductors also expel a magnetic field from their interior, a phenomenon known as the Meissner effect. Superconductivity can be explained by the BCS theory, which says that electrons are able to travel through a solid with no resistance because they couple to form pairs of electrons (Cooper pairs). Hightemperature superconductors haveTc values greater than 30 K. Q: Superconductors expel a magnetic field from their interior. what is this phenomenon known as? A:

OPTIONS:
- weissenberg effect
- eibner effect
- lauer effect
- meissner effect

A: meissner effect

input: OPTIONS:
- deactivation
- bromination
- caramelization
- transamination Now, answer this question: Answer the following question given this paragraph: The Fate of the Carbon Skeleton Any amino acid can be converted into an intermediate of the citric acid cycle. Once the amino group is removed, usually by transamination, the -keto acid that remains is catabolized by a pathway unique to that acid and consisting of one or more reactions. For example, phenylalanine undergoes a series of six reactions before it splits into. Q: Which process helps deaminate amino acids? A:
A:
output: transamination

Answer the following question given this paragraph: If evolution can take a very long time, how can we visualize how it happens? Charles Darwin came up with the idea of an evolutionary tree to represent the relationships between different species and their common ancestors ( Figure below ). The base of the tree represents the ancient ancestors of all life. The separation into large branches shows where these original species evolved into new species. Q: Who created the idea of an evolutionary tree to represent the relationships between different species and their common ancestors? A:

OPTIONS:
- Carl Sagan
- Scopes
- Isaac Newton
- charles darwin

Answer: charles darwin

Problem: OPTIONS:
- sublimation
- freezing
- melting
- vaporization
Q: Answer the following question given this paragraph: The process in which a liquid boils and changes to a gas is called vaporization . The temperature at which a liquid boils is its boiling point. The boiling point of water is 100C (212F). Other types of matter may have higher or lower boiling points. For example, the boiling point of table salt is 1413C. The boiling point of nitrogen is -196C. Q: What is the process in which a liquid boils and changes to a gas? A:
Answer: vaporization

Problem:OPTIONS:
- erosion
- hydro
- evaporation
- thermal

Answer the following question given this paragraph: Discussion for (a) This value is the net work done on the package. The person actually does more work than this, because friction opposes the motion. Friction does negative work and removes some of the energy the person expends and converts it to thermal energy. The net work equals the sum of the work done by each individual force. Strategy and Concept for (b) The forces acting on the package are gravity, the normal force, the force of friction, and the applied force. The normal force and force of gravity are each perpendicular to the displacement, and therefore do no work. Solution for (b) The applied force does work. Q: Friction does negative work and removes some of the energy the person expends and converts it to which kind of energy? A:
****
A: thermal

Problem:OPTIONS:
- acid
- bile
- teeth
- swallowed stones

Answer the following question given this paragraph: The digestive system of birds is unique, with a gizzard that contains swallowed stones for grinding food. Birds do not have teeth. What do you think the stones do? They help them digest their food. Defining characteristics of modern birds also include:. Q: What does the gizzard in birds contain that allows them to grind food? A:
****
A:
swallowed stones
