The answer is that the criteria of classification change with the improved understanding of organisms around us. During the time of Aristotle, not much was known about the living organisms. So, he classified them as he observed. Plants were classified into herbs, shrubs and trees; very much like what’s taught to a second grade student. Animals as Enaima and Anaima based on the presence or absence of RBCs. After him, Carolus Linnaeus tried his hand over classification. He came up with the 2 kingdom classification: Plants and Animals. He considered only a set of morphological and physiological criteria to decide the kingdom to which an organism belongs. It includes presence of cell wall, mode of nutrition, contractile vacuole, locomotion and others. Based on these criteria, he included widely differing organisms into a single kingdom, for example, fungi, bacteria, algae, and higher plants were included into plant kingdom just because they have cell wall as a common aspect. Then came, Ernst Haeckel, who came with a third kingdom of Protista to include unicellular organisms. Copeland gave a 4 kingdom classification segregating unicellular organisms into 2 separate kingdoms based on their nuclear structure. R.H. Whittaker came next introducing the most accepted 5 kingdom classification system. You should understand one thing that man’s knowledge of classifying organisms improved with the improving technologies available to him, which he exploited to very effective extent. Carl Woese gave the 6 kingdom classification and 3 domain system based on the 16S rRNA sequence.
Our understanding of organisms around us is improving day by day and the system of classification will also change further in pace with the improvement in technology.
I hope this helps! :D]

Because of symptoms and age, we would consider some diagnosis of bronchitis due to RSV infection, pneumonia because of Haemophilus influenza infections, and pertussis infection including apnea. Here I can say the answer is pneumonia due to infection of Haemophilus influenza.
The kind of treatment we can give depending on my diagnosis are; high dosage of oral erythromycin to clear the infection bacteria, supportive therapies in hospital in order to maintain blood oxygen levels and in open airways, low dosage of erythromycin which is given intravenously to clear the infection of bacteria which I can say it is the best treatment.
Some of the treatment for the infant to diminish such infection chances are MMR vaccines, toxin antiserum DTaP vaccine, influenza shot which I can recommend for the infant.
The best reason I can say about these conditions and symptoms are associated with pneumonia whereby we can say the low dose of erythromycin which is given intravenously is effective. The best prophylactic treatment is influenza shots.
Hydrogen atoms are compressed
together by the enormous gravitational force
of the sun, causing them to fuse int a helium atom (which is heavier than
hydrogen), subatomic particles and enormous
release of atomic energy. The attached
picture shows the sequence of the main reaction
at the core of the sun.
Answer:
Humans an hunt second-order consumers.
Answer:
Photosynthesis doesn't occur at night. When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. ... the rate of photosynthesis is higher than the rate of respiration. there is a net release of oxygen and a net uptake of carbon dioxide.
