INTRODUCTION TO THE BACTERIAL CELL (EUBACTERIA)

Bacteria (singular: bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most habitats on the planet, growing in soil, water, acidic hot springs, radioactive waste, and deep in the Earth's crust, as well as in organic matter and the live bodies of plants and animals, providing outstanding examples of mutualism in the digestive tracts of humans, termites and cockroaches. Bacteria are microscopic living things that were among the first creatures to inhabit the earth. They can be found almost anywhere, and they come in all forms and shapes, some being harmful to other living things like man, while some are beneficial. People are often scared of being contaminated or infected by bacteria but the types of bacteria which are actually useful in maintaining health and preventing disease.

CLASSIFICATION OF BACTERIA

The classification of the invisible bacterial life. Bacterial classification is based on several major properties,

CLASSIFICATION OF BACTERIA BASED ON GRAM STAINING
This method of classification of bacteria was discovered by Hans Joachim Christian Gram 1883, a Danish Physician, while attempting to differentiate bacteria from human tissue by different staining methods. He noted differences in stain retention by bacteria due to

    Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its happiness so the snails with thinner shells will likely be targeted first and eventually eliminated.…

    I think that free earlobes is the dominant trait (Because none of the 20 people I surveyed had attached earlobes). I think that no hair on knuckles is the dominant trait (Because 75% of the people I that surveyed had it). I think that straight hair line is the dominant trait ( Because 75% of the people I that surveyed had it). I don't know whether straight hair or curly hair is the dominant trait (Because it was an even split). I think that no cleft chin is the dominant trait (Because 90% of the people I surveyed had it). I don't seem to exhibit any of the recessive traits shown here. I shared the same chin shape, earlobes and amount of hair on knuckles. I didn't exhibit any trait that was not exhibited in my parents. If an offspring exhibited a recessive trait that neither parent exhibited, it would mean that both parents carried it. I was surprised that none of the 20 people had attatched earlobes. Yes, It is possible that a recessive trait…

    What is it this creatures? First, we think about who named and looked out this creature “Bacteria”? And second, we think about when did “Bacteria” appear in our world? Third, we think about what is made of “Bacteria”? First, the word “Bacteria” is the plural of the New Latin “Bacterium” which is the latinisation of the βακτήριον (baktērion), the diminutive of βακτηρία (baktēria), meaning "staff, cane", because the first ones to be discovered were rod-shaped.Second, the ancestors of modern bacteria were single-cell microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. For about 3 billion years, all organisms were microscopic, and bacteria and archaea were the dominant forms of life. Although bacterial fossils exist, their lack of distinctive…
