Answer the following question given this paragraph: Plant Parasites Protist parasites of terrestrial plants include agents that destroy food crops. The oomycete Plasmopara viticola parasitizes grape plants, causing a disease called downy mildew (Figure 23.33). Grape plants infected with P. viticola appear stunted and have discolored, withered leaves. The spread of downy mildew nearly collapsed the French wine industry in the nineteenth century. Q: What disease is caused when the oomycete plasmopara viticola parasitizes grape plants? Choices: - dainty mildew - alkaline mildew - toxic mildew - downy mildew A:
downy mildew
Answer the following question given this paragraph: We see examples of mammals (other than people!) serving our needs everywhere. We have pets that are mammals, such as dogs and cats. Mammals are also used around the world for transport. For example, horses, donkeys, mules, or camels ( Figure below ) may be the primary means of transport in some parts of the world. Mammals also do work for us. Service dogs can be trained to help the disabled. These include guide dogs, which are assistance dogs trained to lead blind and visually impaired people around obstacles. Horses and elephants can carry heavy loads. Humans also use some mammals for food. For example, cows and goats are commonly raised for their milk and meat. Mammals' more highly developed brains have made them ideal for use by scientists in studying such things as learning, as seen in maze studies of mice and rats. Q: What broad group of animals - which includes rats, dogs and camels - have highly developed brains and often perform work for humans? Choices: - arachnids - reptiles - amphibians - mammals A:
mammals
Q: Answer the following question given this paragraph: pH Regulation Recall that enzymes lose their three-dimensional conformation and, therefore, their function if the pH is too acidic or basic. This loss of conformation may be a consequence of the breaking of hydrogen bonds. Move the pH away from the optimum for a specific enzyme and you may severely hamper its function throughout the body, including hormone binding, central nervous system signaling, or myocardial contraction. Proper kidney function is essential for pH homeostasis. Q: Proper kidney function is essential for homeostasis of what level, which in turn helps ensure the functioning of enzymes? Choices: - oxygen - calcium - ions - ph A:
A: ph
Question: Answer the following question given this paragraph: Mitosis in the Eukaryotic Cell Cycle. Mitosis is the multi-phase process in which the nucleus of a eukaryotic cell divides. Q: What is the multi-phase process in which the nucleus of a eukaryotic cell divides? Choices: - fission - Osmosis - cytokinesis - mitosis A:
Answer: mitosis

Answer the following question given this paragraph: By the beginning of the Paleozoic, organisms had developed shells. Shells could hold their soft tissues together. They could protect the organisms from predators and from drying out. Some organisms evolved external skeletons, called exoskeletons. Organisms with hard parts also make good fossils. Fossils from the Cambrian are much more abundant than fossils from the Precambrian. Q: What are external skeletons known as? Choices: - tentacles - exoskins - scales - exoskeletons A:
(Answer)
exoskeletons
