Answer the following question given this paragraph: Carboxylic acids are weak acids (see the chapter on acids and bases), meaning they are not 100% ionized in water. Generally only about 1% of the molecules of a carboxylic acid dissolved in water are ionized at any given time. The remaining molecules are undissociated in solution. We prepare carboxylic acids by the oxidation of aldehydes or alcohols whose OH functional group is located on the carbon atom at the end of the chain of carbon atoms in the alcohol:. Q: Carboxylic acids are weak acids, meaning they are not 100% ionized in what? Choices: - air - ethanol - liquid - water A:
water
Answer the following question given this paragraph: Epithelial tissue is made up of layers of tightly packed cells that line the surfaces of the body. Examples of epithelial tissue include the skin, the lining of the mouth and nose, and the lining of the digestive system. Q: Tissue is made up of layers of tightly packed cells that line the surfaces of the body, such as skin. Choices: - weak tissue - neural tissue - resultant tissue - epithelial tissue A:
epithelial tissue
Q: Answer the following question given this paragraph: percent of the Amazon rainforest was lost. Rates are higher in other tropical rainforests. What we are likely to notice on a day-to-day basis as a result of biodiversity loss is that food will be more difficult to produce, clean water will be more difficult to find, and the rate of development of new medicines will become slower, as we depend upon other species for much of these services. This increased loss of biodiversity is almost entirely a result of human activities as we destroy species' habitats, introduce disruptive species into ecosystems, hunt some species to extinction, continue to warm the planet with greenhouse gases, and influence nature in other ways. Slowing the loss of biodiversity is within our abilities if we make dramatic changes in our consumptive behavior and identify and protect the elements of our ecosystems that we depend on for our lives and welfare. Q: The result of what, in places like the amazon rainforest, is that food will be harder to produce, clean water will be harder to find, and development of new medicines will become slower? Choices: - environmnental loss - pollution loss - biological loss - biodiversity loss A:
A: biodiversity loss
Question: Answer the following question given this paragraph: Gases that absorb heat in the atmosphere are called greenhouse gases . They include carbon dioxide and water vapor. Human actions have increased the levels of greenhouse gases in the atmosphere. This is shown in Figure below . The added gases have caused a greater greenhouse effect. How do you think this affects Earth's temperature?. Q: What is the term for gases that absorb heat in the atmosphere? Choices: - ionic gases - thermal gases - sulfuric gases - greenhouse gases A:
Answer: greenhouse gases

Answer the following question given this paragraph: Range shifts are already being observed: for example, some European bird species ranges have moved 91 km northward. The same study suggested that the optimal shift based on warming trends was double that distance, suggesting that the populations are not moving quickly enough. Range shifts have also been observed in plants, butterflies, other insects, freshwater fishes, reptiles, and mammals. Climate gradients will also move up mountains, eventually crowding species higher in altitude and eliminating the habitat for those species adapted to the highest elevations. Some climates will completely disappear. The rate of warming appears to be accelerated in the arctic, which is recognized as a serious threat to polar bear populations that require sea ice to hunt seals during the winter months: seals are the only source of protein available to polar bears. A trend to decreasing sea ice coverage has occurred since observations began in the mid-twentieth century. The rate of decline observed in recent years is far greater than previously predicted by climate models. Finally, global warming will raise ocean levels due to melt water from glaciers and the greater volume of warmer water. Shorelines will be inundated, reducing island size, which will have an effect on some species, and a number of islands will disappear entirely. Additionally, the gradual melting and subsequent refreezing of the poles, glaciers, and higher elevation. Q: Global warming will raise ocean levels due to melt water from glaciers and the greater volume of what? Choices: - greenhouse gases - rainforests - rain - warmer water A:
**Answer**
warmer water
