Answer the following question given this paragraph: ART CONNECTION QUESTIONS 1. Figure 7.11 Dinitrophenol (DNP) is an uncoupler that makes the inner mitochondrial membrane leaky to protons. It was used until 1938 as a weight-loss drug. What effect would you expect DNP to have on the change in pH across the inner mitochondrial membrane? Why do you think this might be an effective weight-loss drug? 2. Figure 7.12 Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the. Q: Dinitrophenol (dnp) is an uncoupler that makes the inner mitochondrial membrane leaky to protons. it was used until 1938 as a what? Choices: - immune system booster - bone density drug - sleep loss drug - weight loss drug A:
weight loss drug

Answer the following question given this paragraph: As the fast-moving cold air mass keeps advancing, so does the cold front. Cold fronts often bring sudden changes in the weather. There may be a thin line of storms right at the front that moves as it moves. In the spring and summer, the storms may be thunderstorms and tornadoes. In the late fall and winter, the storms may bring snow. After a cold front passes, the cold air mass behind it brings cooler temperatures. The air is likely to be less humid as well. Can you explain why?. Q: What type of fronts often bring sudden changes in the weather, including different types of precipitation, depending on the season? Choices: - stationary fronts - occluded fronts - warm fronts - cold fronts A:
(Answer)
cold fronts

Answer the following question given this paragraph: Prophase is the first and longest phase of mitosis, see Figure below . During prophase, the chromatin (DNA) coils up into visible chromosomes, each made up of two sister chromatids held together by the centromere. Also during this phase, the nucleolus disappears, and the spindle begins to form from the centrioles. Most eukaryotic cells contain structures known as centrosomes, consisting of a pair of centrioles. During prophase, the centrioles begin to move to opposite ends, or poles, of the cell. As the centrioles migrate, the fiber-like spindle begins to elongate between the centrioles. The spindle is a thin, cage-like structure made out of microtubules. In plant cells, the spindle forms without centrioles. The spindle plays an essential role moving chromosomes and in the separation of sister chromatids. Q: What is the first and longest phase of mitosis known as? Choices: - metaphase - telophase - anaphase - prophase A:
(A).
prophase

Q: What do we call the movement of individuals into a population from other areas? Choices: - pilgrimage - nomadic - assimilation - immigration A:

Ans:immigration
Ques:Answer the following question given this paragraph: Chemical and physical changes in a system may be accompanied by either an increase or a decrease in the disorder of the system, corresponding to an increase in entropy (S> 0) or a decrease in entropy (S < 0), respectively. As with any other state function, the change in entropy is defined as the difference between the entropies of the final and initial states: S = Sf Si. When a gas expands into a vacuum, its entropy increases because the increased volume allows for greater atomic or molecular disorder. The greater the number of atoms or molecules in the gas, the greater the disorder. The magnitude of the entropy of a system depends on the number of microscopic states, or microstates, associated with it (in this case, the number of atoms or molecules); that is, the greater the number of microstates, the greater the entropy. We can illustrate the concepts of microstates and entropy using a deck of playing cards, as shown in Figure 18.7 "Illustrating Low- and High-Entropy States with a Deck of Playing Cards". In any new deck, the 52 cards are arranged by four suits, with each suit arranged in descending order. If the cards are shuffled, however, there are approximately 1068 different ways they might be arranged, which corresponds to 1068different microscopic states. The entropy of an ordered new deck of cards is therefore low, whereas the entropy of a randomly shuffled deck is high. Card games assign a higher value to a hand that has a low degree of disorder. In games such as five-card poker, only 4 of the 2,598,960 different possible hands, or microstates, contain the highly ordered and valued arrangement of cards called a royal flush, almost 1.1 million hands contain one pair, and more than 1.3 million hands are completely disordered and therefore have no value. Because the last two arrangements are far more probable than the first, the value of a poker hand is inversely proportional to its entropy. We can see how to calculate these kinds of probabilities for a chemical system by considering the possible...

Choices: - enthalpy - vibration - volume - entropy A:
