Answer: A) Expose a sample to visible light.
Explanation: It is because in this manner the sample can be exposed to the full spectrum of light. By doing this the chlorophyll in the positive control is active and so is the DCPIP and in this, it should be reduced by the photosystem.

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.

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.

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)

What two molecules are produced during Photosynthesis?
Answer:
outputs Glucose, oxygen
Explanation:
Explanation:
photosynthesis requires sunlight, carbon dioxide and water as starting reactants (figure 5.5). After the process is complete, photosynthesis releases oxygen and produce carbohydrate molecule, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
During the process of photosynthesis, cell use carbon dioxide and energy from the sun to make sugar molecules and oxygen.
