Answer:
c) receptor; control center; effector.
Explanation:
Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.
For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.
Answer:
The oil produced in United States is light and low sulfur content and they do not have proper processing facilities, hence purchase it from other countries.
Explanation:
About 9.93 million barrels per day U.S purchase oil from 86 countries. Because the crude oil present is not homogeneous in nature. It is very light in nature with low sulfur content or may be high,this particular factor depends upon the method of the refining. Most of the oil are being exported by the Saudi Arabia and then comes Russia followed by Iraq. Despite the collapse in price, U.S. dependence on foreign oil should continue to decrease.
The biogeochemical cycle of water, or the hydrological cycle describes the way that water (Hydrogen Dioxide or H 2 O) is circulated and recycled throughout Earth’s systems. All living organisms, without exception, need water to survive and grow, making it one of the most important substances on Earth.

Answer:
Q3 the right answer is A) the aluminium pot
QUESTION 4 B. A lake full of water ( also depends on volume and mass of water)
Explanation:
Q3. the specific heat capacity is the amount of heat one gram of substance absorb or release to change temperature by one degree centigrade.
The aluminum heats faster than the water because it requires less energy to heat it up.
but its also have the radiates/conducts away all of its heat so rapidly that it cools off much faster than anything else.
Q4.
If a swimming pool and lake full of water, both full of water at the same temperature were subjected to the same input of heat energy, the lake would certainly rise in temperature more quickly than the swimming pool. The heat capacity of an object depends both on its mass and its chemical composition. Because of its much larger mass, the lake full of water has a larger heat capacity than the swimming pool full of water.
