Answer the following question given this paragraph: As you can see from Figure above , a mitochondrion has an inner and outer membrane. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane. Q: What do mitochondrions have an inner and outer version of? A:
****
A: membrane

Answer the following question given this paragraph: Endoskeleton An endoskeleton is a skeleton that consists of hard, mineralized structures located within the soft tissue of organisms. An example of a primitive endoskeletal structure is the spicules of sponges. The bones of vertebrates are composed of tissues, whereas sponges have no true tissues (Figure 38.4). Endoskeletons provide support for the body, protect internal organs, and allow for movement through contraction of muscles attached to the skeleton. Q: A skeleton that consists of hard, mineralized structures located within the soft tissue of organisms is called what? A:
OPTIONS:
- exoskeleton
- calcium deposits
- hydrostatic skeleton
- endoskeleton
endoskeleton

Answer the following question given this paragraph: Summary 16.1 Spontaneity Chemical and physical processes have a natural tendency to occur in one direction under certain conditions. A spontaneous process occurs without the need for a continual input of energy from some external source, while a nonspontaneous process requires such. Systems undergoing a spontaneous process may or may not experience a gain or loss of energy, but they will experience a change in the way matter and/or energy is distributed within the system. 16.2 Entropy Entropy (S) is a state function that can be related to the number of microstates for a system (the number of ways the system can be arranged) and to the ratio of reversible heat to kelvin temperature. It may be interpreted as a measure of the dispersal or distribution of matter and/or energy in a system, and it is often described as representing the "disorder" of the system. For a given substance, Ssolid < Sliquid < Sgas in a given physical state at a given temperature, entropy is typically greater for heavier atoms or more complex molecules. Entropy increases when a system is heated and when solutions form. Using these guidelines, the sign of entropy changes for some chemical reactions may be reliably predicted. 16.3 The Second and Third Laws of Thermodynamics The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, Suniv > 0. If Suniv < 0, the process is nonspontaneous, and if Suniv = 0, the system is at equilibrium. The third law of thermodynamics establishes the zero for entropy as that of a perfect, pure crystalline solid at 0 K. With only one possible microstate, the entropy is zero. We may compute the standard entropy change for a process by using standard entropy values for the reactants and products involved in the process. 16.4 Free Energy Gibbs free energy (G) is a state function defined with regard to system quantities only and may be used to predict the spontaneity of a process. A negative value for G indicates a spontaneous process; a positive G indicates a... Q: What kind of process occurs without the need for a continual input of energy from some external source? A:
OPTIONS:
- Decay Process
- Different Process
- induced process
- spontaneous process

Answer: spontaneous process

Question: Answer the following question given this paragraph: The frequency of a wave is the same as the frequency of the vibrations that caused the wave. For example, to generate a higher-frequency wave in a rope, you must move the rope up and down more quickly. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude. You can see examples of different frequencies in the Figure below (Amplitude is the distance that particles of the medium move when the energy of a wave passes through them. ). Q: What is the ratio of a wave frequency to its vibration frequency? A:
OPTIONS:
- one
- two
- three
- same
Answer: same

input with options: Answer the following question given this paragraph: Metabolic acidosis is problematic, as lower-than-normal amounts of bicarbonate are present in the blood. The pCO2 would be normal at first, but if compensation has occurred, it would decrease as the body reestablishes the proper ratio of bicarbonate and carbonic acid/CO2. Respiratory acidosis is problematic, as excess CO2 is present in the blood. Bicarbonate levels would be normal at first, but if compensation has occurred, they would increase in an attempt to reestablish the proper ratio of bicarbonate and carbonic acid/CO2. Alkalosis is characterized by a higher-than-normal pH. Metabolic alkalosis is problematic, as elevated pH and excess bicarbonate are present. The pCO2 would again be normal at first, but if compensation has occurred, it would increase as the body attempts to reestablish the proper ratios of bicarbonate and carbonic acid/CO 2. Respiratory alkalosis is problematic, as CO2 deficiency is present in the bloodstream. The bicarbonate concentration would be normal at first. When renal compensation occurs, however, the bicarbonate concentration in blood decreases as the kidneys attempt to reestablish the proper ratios of bicarbonate and carbonic acid/CO2 by eliminating more bicarbonate to bring the pH into the physiological range. Q: Why is respiratory acidosis considered to be problematic? A:
OPTIONS:
- causes acid stomach
- excess oxygen in blood
- causes suffocation
- excess co2 in blood
output: excess co2 in blood

Problem: OPTIONS:
- temperature
- salinity
- animal species
- water depth
Q: Answer the following question given this paragraph: In addition to the amount of salts, other conditions in ocean water vary from place to place. One is the amount of nutrients in the water. Another is the amount of sunlight that reaches the water. These conditions depend mainly on two factors: distance from shore and depth of water. Oceans are divided into zones ( Figure below ) based on these two factors. The ocean floor makes up another zone. Q: Oceans are divided into zones bases on distance from shore and what other factor? A:
Answer:
water depth
