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).

Why does the reporter have a tube up his nose? why does the reporter have a tube up his nose? to replace the salts and other ion
Helga [31]
The correct answer is to accurately measure core temperature.
The tube seen entering the reporter's nose is a thermistor which is used to measure the core temperature of the body with very high levels of accuracy. The tube reaches the esophagus, which is one of the most preferred locations for measuring the core temperature.
The core body temperature is the operating temperature of the human body and it refers to the temperature of the deeper structures of the body instead of the peripheral tissues. 
The esophagus is close to the left ventricle of the heart, it has a deep body location and a quick response to any changes in the body temperature.

tatuchka [14]
The best option is D. Based on scientific evidence about algal bloom, it would be best to evacuate all humans from the area around the lake. Algal bloom is caused by excess nutrients in the lake. This occurrence is linked to the death of fishes, plants, mammals and birds. Also. it has been said to cause human illnesses. Thus, to avoid this, it would be best to stay away from the lake with algal bloom.
