Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water, "light", and sunthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP).
Answer:
o determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. ... With absolute age dating, you get a real age in actual years

Social media help in addressing substance abuse through awareness and sensitization are going on to make know of the harm and danger in substance abuse.
<h3>What is social media?</h3>
Social media are online platforms that allows the user to create, write or display content and share with viewers and it also helps to access information and participate in many social networking.
Socal media campaigns have been done on television programs and other social media platforms to prevent the illicit use of drug by young and old people. This is because most young people visit the online platforms more and awareness and sensitization are going on to make know of the harm and danger in substance abuse.
Therefore, media help in addressing substance abuse through awareness and sensitization are going on to make know of the harm and danger in substance abuse.

The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.
<h3>How to calculate amount of landscaping plants?</h3>
just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
<h3>How to calculate the spacing between plants?</h3>
If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).
With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
