6. Why can't water be used to dissolve the
caffeine found in coffee and tea?
Alcohol is used to extract caffeine
Tea's chief component is cellulose, which is not soluble in water. Caffeine is water soluble, but so are tannins and gallic acid, which have been established during the heating process of tea leaves. The latter two components can be converted to insoluble in water calcium salts.
What is solubility?The maximum amount of a substance that will dissolve in a given amount of solvent at a given temperature is defined as solubility.
Solubility is a property of a specific solute-solvent combination, and the solubilities of different substances vary greatly.
It is one of the critical parameters for achieving the desired drug concentration in systemic circulation for the desired (anticipated) pharmacological response.
Caffeine is more soluble in nonpolar methylene chloride than in water, so it will migrate to the methylene chloride layer (known as the organic layer). Because the organic layer is denser than water, it will be at the bottom.
Thus, water can not be used to dissolve the caffeine found in coffee and tea.

What term is used to describe the state at which a solute moves down its concentration gradient
through the plasma membrane and becomes evenly distributed in the cytosol?
Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.
What is Diffusion?Diffusion is the type of net movement of particles from an area of higher concentration to an area of lower concentration. It is driven by the gradient in Gibbs free energy or chemical potential.
This occurs through the semi-permeable membrane like the plasma membrane. Diffusion of small molecules and macromolecules such as proteins in aqueous solutions plays an important role in microorganisms, plants and animals.
Few examples of Diffusion are:
Perfume is sprayed in one part of the room so that it can spread easily so that we can feel its smell everywhere. A drop of food coloring spread throughout the water in a glass, the whole glass will be colored.Thus, Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.

8. A wise old wizard once told me that when your muscles use ATP they are really using light
energy. What did the wise wizard mean?
Answer: in humans, we don't use light energy to make ATP but in plants however, they create ATP in a proccess called photosynthesis, this process requires light to be absorbed twice, once in each photosystem, and it makes ATP. In fact, it's called photophosphorylation because it involves using light energy (photo) to make ATP from ADP (phosphorylation)

True or False
Answer:
True
Explanation:
Minerals are prone to destruction by different elements such as oxygen, heat, and acids treatment. The given statement is true. On treatment with these elements, minerals loose their properties.
What are minerals?
Minerals are the naturally occurring inorganic elements or compounds which posses an orderly internal structure and characteristics with the specific chemical composition, crystal form, and properties such as physical properties and chemical properties. Minerals differ from the rocks, which are the naturally occurring solids that are composed of one or more types of minerals.
Minerals show properties which can be lost by the treatment with different elements. Minerals have been found to be prone to destruction by the elements such as oxygen, heat, and acids. Minerals undergo chemical and physical change on treatment with these elements and form different products which show different characteristics than the parent minerals.
