Answer: All the given symptoms describes Pertussis.
Explanation:
Pertussis can also be defined as whooping cough or 100 day cough. It is respiratory disease which is highly contagious.
it is caused by the bacteria Bordetella pertussis. It is also known to be uncontrollable as this condition does not allows the person to breathe properly.
If recognized at early stage then antimicrobial like erythromycin can be used to treat it. The symptoms of this disease lasts for a long time and is not cured easily. Its initial stage includes cold, cough and running nose, same as common cold.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Answer:
it ends in the creation of oxygen from carbon dioxide
Explanation:
Photosynthesis occurs in two stages. The first, specifically luminous or photochemical, depends directly on the light received, the energy of the solar rays between the wavelengths corresponding to the violet, blue, orange and red light. This energy produces the excitation of electrons and causes the breakdown of water molecules, so that oxygen is released and the rest of the energy is transmitted, generating molecules of ATP (Adenosine triphosphate) and NADPH (Nicotinamide adenine dinucleotide phosphate ). These components are used in the next stage, which is known as the dark phase because it does not depend directly on light. This second stage develops in the stroma, the internal aqueous space of the chloroplast. There the energy in the form of ATP and NADPH produced in the photodependent phase is used to fix the carbon dioxide as organic carbon, by means of the Calvin cycle. This consists of a series of chemical reactions in which phosphoacylglycerides are produced with which the plant cell produces nutrients. The process resulted in a compound similar to sugar called glucose (C6 H12 O6).
The phenomenon of photosynthesis carried out by all the terrestrial and aquatic plants of the planet, and also the algae and some bacteria, resulting essential for life on Earth. By absorbing solar energy and carbon dioxide and returning oxygen and carbohydrates, the plant kingdom will become a fundamental part of the natural cycles of energy, carbon and oxygen.
