Answer the following question given this paragraph: The hypothalamus is actually part of the brain (see Figure below ), but it also secretes hormones. Some of its hormones that "tell" the pituitary gland to either secrete or stop secreting its hormones. In this way, the hypothalamus provides a link between the nervous and endocrine systems. The hypothalamus also produces hormones that directly regulate body processes. These hormones travel to the pituitary gland, which stores them until they are needed. The hormones include antidiuretic hormone and oxytocin. Q: What organ is the hypothalamus a part of? Choices: - Nervous system - liver - heart - brain A:
brain

Answer the following question given this paragraph: Echo sounders were used to search for enemy submarines during World War II. The depths they recorded allowed scientists to piece together bathymetric maps of the seafloor. Multi-beam sounders work on research vessels today. Q: What do waves deposit in relatively quiet areas along a shore? Choices: - fish - mud - snow - sand A:
(Answer)
sand
Ques: Answer the following question given this paragraph: Climate and Weather A common misconception about global climate change is that a specific weather event occurring in a particular region (for example, a very cool week in June in central Indiana) is evidence of global climate change. However, a cold week in June is a weather-related event and not a climate-related one. These misconceptions often arise because of confusion over the terms climate and weather. Climate refers to the long-term, predictable atmospheric conditions of a specific area. The climate of a biome is characterized by having consistent temperature and annual rainfall ranges. Climate does not address the amount of rain that fell on one particular day in a biome or the colder-than-average temperatures that occurred on one day. In contrast, weather refers to the conditions of the atmosphere during a short period of time. Weather forecasts are usually made for 48-hour cycles. Long-range weather forecasts are available but can be unreliable. To better understand the difference between climate and weather, imagine that you are planning an outdoor event in northern Wisconsin. You would be thinking about climate when you plan the event in the summer rather than the winter because you have long-term knowledge that any given Saturday in the months of May to August would be a better choice for an outdoor event in Wisconsin than any given Saturday in January. However, you cannot determine the specific day that the event should be held on because it is difficult to accurately predict the weather on a specific day. Climate can be considered "average" weather. Q: What term describes the long-term, predictable atmospheric conditions of a specific area? Choices: - hemosphere - wind patterns - solar activity - climate A:
Ans: climate
(Q).
Answer the following question given this paragraph: Pepsinogen is an inactive form of pepsin; pepsin is the active form of the enzyme. Both enzymes catalyze the hydrolysis of peptide bonds. Chymotrypsin catalyzes the hydrolysis of peptide bonds following aromatic amino acids, while trypsin catalyzes the hydrolysis of peptide bonds following lysine and arginine. Aminopeptidase catalyzes the hydrolysis of amino acids from the N-terminal end of a protein, while carboxypeptidase catalyzes the hydrolysis of amino acids from the Cterminal end of a protein. Q: What catalyzes the hydrolysis of amino acids from the n-terminal end of a protein? Choices: - synthase - testosterone - nucleic acid - aminopeptidase A:
(A).
aminopeptidase
Ques:Answer the following question given this paragraph: People use fresh water from aquifers from springs or wells. Q: What do people use from aquifers from springs or wells? Choices: - oxygen - salt - soil - fresh water A:

Ans:fresh water
Ques:Answer the following question given this paragraph: The standard cell potential is negative, indicating a nonspontaneous reaction. The battery must be capable of delivering at least 1.10 V of direct current in order for the reaction to occur. Another difference between a voltaic cell and an electrolytic cell is the signs of the electrodes. In a voltaic cell, the anode is negative and the cathode is positive. In an electrolytic cell, the anode is positive because it is connected to the positive terminal of the battery. The cathode is therefore negative. Electrons still flow through the cell form the anode to the cathode. Q: What type of cell has negative anode is positive cathode? Choices: - picric cell - planetoid cell - non-voltaic cell - voltaic cell A:

Ans:
voltaic cell
