What are some things water will adhere to? and What are some things water will not adhere to?
Answers
Answer:
1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).
2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

What are the theory of cell ?
Answers
Answer:
that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
Explanation:
9. Most agricultural fields receive inputs of phosphorus, calcium, and magnesium, which are usually obtained by mining rocks containing those elements, grinding them up, and adding them
to fertilizers. Assess the likely impact of this practice on the demand for certain rocks and on soil dynamics with regards to both a) a nutrient cycle and b) a feedback loop.
Answers
This practice has a great impact on the demand of certain rocks.
There is great impact of this practice on the demand for certain rocks because they are necessary for the higher productivity of crops so their demand as well as price of that rock increases. This practice of adding of nutrients has good effects on soil dynamics as well as on nutrient cycle because these nutrients are not only use by the plants as well as by soil in order to maintain its structure.
A feedback loop is the part of a system in which some portion of the system's output is used as input for future operations. In this situation, the feedback loop is negative because all the materials are used from outside and the output can't be used in the system so we can conclude that this practice has a great impact on the demand of certain rocks.

Look at the diagram. Name organ 1.
Answers
Answer:
Organ 1: Stomach
Explanation:
The stomach holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a useable form. The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The large intestines are to absorb water and salts from the material that has not been digested as food and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption have already taken place. The small intestines have three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.

What is Cicero's philosophy of government?
Answers
Answer:
Cicero proposed that the ideal government "is formed by an equal balancing and blending" of monarchy, democracy, and aristocracy. In this "mixed state," he argued, royalty, the best men, and the common people all should have a role.
Answer:
Like Polybius, Cicero has suggested three types of government—royalty, aristocracy and democracy. But in each form of government there is the germ of corruption and instability and this leads to the fall of government. Only a mixed form of government is the proper guarantee of stability and corruption-free society.
