Answer:

its very important in our day to day life

Explanation:

the sun is our closest star and there are many theorys about it that need to be proven right or wrong

Understanding the Sun will help us better understand stellar life cycles and the origins of our solar system. The cost of the equipment needed to research the Sun is prohibitive. The Earth's distance from the Sun must also be considered, as well as how equipment must resist the Sun's intense heat.

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.

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:

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.

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.

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.

Explanation:

The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.

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)

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.

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.

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.
