Small living organismsWater dropletsMetals and metallic objectsNon-magnetic objectsWhat are magnetic fields?A magnet or an electric current will be surrounded by a magnetic field, a type of physical phenomenon. They are formed by charges or magnetic dipoles, which can have an effect on other adjacent objects. Magnetic dipoles are commonly found in magnets. Magnetic field lines, which lie perpendicular to the direction of the magnetic force, are commonly used to represent the magnitude and direction of the magnetic field.
Electric motors, generators, MRI equipment and particle accelerators are some examples of practical uses of magnetic fields. They are also used for data storage in gadgets such as credit cards and hard disks. Additionally, magnetic fields have a significant effect on the behavior of a variety of natural phenomena, including compass needles.

7. What is a solvent? What is a solute? What is the difference between the two?
8. What are substances that release hydrogen ions called? What about more hydroxide ions?
9. What is the measure of H+ in a solution called? What is the value for water? What numbers are acidic and which ones are basic? You live in a one story house made entirely of redwood. What color would the stairs be?
Answer:
8. An Acid and a Base.
7. A solvent is a substance that dissolves a solute, resulting in a solution (able to dissolve other substances). A solute is the dissolved matter in a solution. The key difference between solvent and solute is that the solute is the one to be dissolved while, the solvent is responsible for dissolving it.
6. Homogeneous solutions are solutions with uniform composition and properties throughout the solution. Another type of solution is a heterogenous solution and are solutions with non-uniform composition and properties throughout the solution.
5. A mixture is composed of two or more substance, but they are not chemically combined.
Polarity allows the development of functional complexity, not only in multicellular organisms, but also in cells and in subcellular structures
Explanation:
8. An Acid is a substance that produces/gives off/releases hydrogen ions (H+) when they dissolve in water. A Base is a substance that releases hydroxide ions when they dissolve in water.

Explanation:
After swimming in the pool for 2 hours, your friend starts to complain because his fingers and toes are wrinkled. Use the concept of osmosis to explain why. Be sure to include the following in your explanation: The terms hypotonic, isotonic, and/or hypertonic (as well as what they mean) • The overall direction of water movement and reason why • How the movement of water causes his fingers and toes to change • A picture if necessary
Answer:
Explanation:
Osmosis is the spontaneous movement of molecules from low concentration to high concentration. The finger is hypertonic to the swimming pool, which means that it has a higher osmotic pressure. The pool is hypotonic to the finger, which means it has a lower osmotic pressure. Because osmosis goes from low to high concentration, water will seep into the finger, causing it to swell and become wrinkly. This balances out the concentration on both sides of the semipermeable membrane (skin on the finger) and makes them isotonic, meaning they have the same concentration.
