Answer the following question given this paragraph: Both mammals and birds evolved endothermy. Endothermy means controlling body temperature within a narrow range from the inside through biochemical or physical means. For example, on a cold day, an endotherm may produce more body heat by increasing its rate of metabolism. On a hot day, it may give off more heat by increasing blood flow to the surface of the body. That way, some of the heat can radiate into the air from the body's surface. Endothermy requires more energy (and food) than ectothermy. However, it allows the animal to stay active regardless of the temperature outside.

Q: What term means controlling body temperature within a narrow range from the inside through biochemical or physical means? Choices: - exothermy - regulation - evaporation - endothermy A:
endothermy
Answer the following question given this paragraph: A battery is an electrochemical cell or series of cells that produces an electric current. In principle, any galvanic cell could be used as a battery. An ideal battery would never run down, produce an unchanging voltage, and be capable of withstanding environmental extremes of heat and humidity. Real batteries strike a balance between ideal characteristics and practical limitations. For example, the mass of a car battery is about 18 kg or about 1% of the mass of an average car or light-duty truck. This type of battery would supply nearly unlimited energy if used in a smartphone, but would be rejected for this application because of its mass. Thus, no single battery is "best" and batteries are selected for a particular application, keeping things like the mass of the battery, its cost, reliability, and current capacity in mind. There are two basic types of batteries: primary and secondary. A few batteries of each type are described next. Q: What device is an electrochemical cell or series of cells that produces an electric current? Choices: - reactor - magnet - generator - battery A:
battery
Q: Answer the following question given this paragraph: According to the Aufbau process, sublevels and orbitals are filled with electrons in order of increasing energy. Since the s sublevel consists of just one orbital, the second electron simply pairs up with the first electron as in helium. The next element is lithium and necessitates the use of the next available sublevel, the 2 s . Q: According to which process, sublevels and orbitals are filled with electrons in order of increasing energy? Choices: - Schrodinger's cat - hausen - particle dynamics - aufbau A:
A: aufbau
Question: Answer the following question given this paragraph: An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds. The subscripts for the ions in the chemical formulas become the coefficients of the respective ions on the product side of the equation. Shown below are dissociation equations for NaCl, Ca(NO 3 ) 2 , and (NH 4 ) 3 PO 4 . Q: What do you call the separation of ions that occurs when a solid ionic compound dissolves? Choices: - deformation - decomposition - dissolution - dissociation A:
Answer: dissociation

Answer the following question given this paragraph: Q: Most plants grow continuously, except for what periods? Choices: - abnormal - mutant - winter - dormant A:
**Answer**
dormant
Q: Answer the following question given this paragraph: The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels. Q: What are the different feeding positions in a food chain or web called? Choices: - neural levels - Primary Level - convoluted levels - trophic levels A:
A: trophic levels
