Answer the following question given this paragraph: Human organ systems work together to carry out many of their functions. The skeletal and muscular systems are no exception. Q: Groupings of related organs in the human body are referred to as "organ" what? Choices: - conditions - bodies - functions - systems A:
systems

Answer the following question given this paragraph: Neural Regulation The nervous system plays a critical role in the regulation of vascular homeostasis. The primary regulatory sites include the cardiovascular centers in the brain that control both cardiac and vascular functions. In addition, more generalized neural responses from the limbic system and the autonomic nervous system are factors. Q: What system plays a critical role in the regulation of vascular homeostasis? Choices: - endocrine system - circulatory system - renal system - nervous system A:
(Answer)
nervous system
Ques: Answer the following question given this paragraph: Then, about 2 or 3 billion years ago, oxygen was gradually added to the atmosphere by early photosynthetic bacteria. After that, living things could use oxygen to break down glucose and make ATP. Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration . Q: Cellular respiration that proceeds in the presence of oxygen is known as what? Choices: - digestive respiration - anaerobic respiration - kinetic respiration - aerobic respiration A:
Ans: aerobic respiration

Answer the following question given this paragraph: Sound Auditory stimuli are sound waves, which are mechanical, pressure waves that move through a medium, such as air or water. There are no sound waves in a vacuum since there are no air molecules to move in waves. The speed of sound waves differs, based on altitude, temperature, and medium, but at sea level and a temperature of 20 C (68 F), sound waves travel in the air at about 343 meters per second. As is true for all waves, there are four main characteristics of a sound wave: frequency, wavelength, period, and amplitude. Frequency is the number of waves per unit of time, and in sound is heard as pitch. High-frequency (15.000Hz) sounds are higher-pitched (short wavelength) than low-frequency (long wavelengths; 100Hz) sounds. Frequency is measured in. Q: Because sound waves must move through a medium, there are no sound waves in a what? Choices: - solid - liquid - gas - vacuum A:
(A).
vacuum
Ques:Answer the following question given this paragraph: When air is very humid, it doesn't have to cool very much for water vapor in the air to start condensing. The temperature at which condensation occurs is called the dew point. The dew point varies depending on air temperature and moisture content. It is always less than or equal to the actual air temperature, but warmer air and moister air have dew points closer to the actual air temperature. That's why glasses of cold drinks "sweat" more on a hot, humid day than they do on a cool, dry day. For more details on the dew point, read the short article at this URL: http://www. kidsgeo. com/geography-for-kids/0108-dew-point. php. Q: Dew point is the temperature at which what occurs? Choices: - combustion - fermentation - precipitation - condensation A:

Ans:condensation
Ques: Answer the following question given this paragraph: Although neon has just one more electron than fluorine in its outer energy level, that one electron makes a huge difference. Fluorine needs one more electron to fill its outer energy level in order to have the most stable arrangement of electrons. Therefore, fluorine readily accepts an electron from any element that is equally "eager" to give one up, such as the metal lithium or sodium. As a result, fluorine is highly reactive. In fact, reactions with fluorine are often explosive, as you can see in the URL below. Neon, on the other hand, already has a full outer energy level. It is already very stable and never reacts with other elements. It neither accepts nor gives up electrons. Neon doesn't even react with fluorine, which reacts with all other elements except helium. Q: Which has more electrons, neon or fluorine? Choices: - the same - fluorine - neither - neon A:
Ans:
neon
