The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter.
- If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid.
- If particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid.
- If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas.
Answer: The Dust Bowl was caused by several economic and agricultural factors, including federal land policies, changes in regional weather, farm economics and other cultural factors. After the Civil War, a series of federal land acts coaxed pioneers westward by incentivizing farming in the Great Plains.
Explanation:
1) Manifest Destiny: The US Government wanted settlers to move onto the Plains as they needed the land to be settled and farmed and for communities and towns to grow up and expand. This was needed if the USA was to be a rich and successful country. The government therefore promoted the idea of Manifest Destiny.
The type of control is described by the response of the operon when no regulatory protein is extant. In the case of negative regulator, the genes in the operon are distinct unless they are switched off by a repressor protein. Therefore the operon will be turned on essential (the genes will be prcise) when the repressor in inactived. In the case of positive control, the genes are distinct only when an active regulator protein, an activator, is present, Thus the operon will be turned off when the positive regulatory protein is missing or inactivated.
Answer: The correct answer is option 3) The amount of matter within the system remains the same and 5) The cycle has a well-defined starting and stopping point.
A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.
In a closed system, the cycle has a well-defined starting and stopping point.
Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 1) and 5)
