In evolution, bacteria have produced nutrition for communities of living organisms through photosynthesis and chemosynthesis. Other significances both ecological and evolutionary includes: they are decomposers of ecosystems (they decay dead organisms to release elements needed by other living organisms), the metabolic processes of some bacteria produced the first oxygen gas in the atmosphere, they aid in atmospheric nitrogen fixation and also as ecological decomposers by cleaning environment and releasing elements needed by other organisms from dead decaying matter.
In symbiosis, parasites obtain nutrients and nourishment and harm their hosts, while they get nourishment and nutrients and neither do they harm nor benefit their hosts. On the other hand, mutualists benefit their hosts.
Sexual reproduction is advantageous in that it results in variation e.g offsprings of human can have traits from all the four grand parents. Asexual reproduction, on the other hand, is advantageous because it results in the in production of great numbers of offsprings hence high survival chances of a given species.
In mitosis process, one nucleus divides into two identical nuclei while meiosis is the process by which one nucleus with two copies of each chromosome divides into four nuclei with one copy of each chromosome. ...Download file to see next pagesRead More

...some food materials as more significant than others do (Schonfield 2011). In the presence of the significantly treasured food materials, squirrels will prefer the food handling behavior and assume the vigilance for some time. At such points, the squirrel takes a risk of danger from predators, but prefers to take a worthy risk. The gray squirrel exhibits diurnal activity and this translates to the fact that these squirrels devote their dawns and dusks trying to find edible materials. Its natural adaptations present it with the capacity to easy movement from tree to tree (Parker and Nilon 2008). The gray squirrel does not present high levels of selection but settles on the available food materials. Although relatively...

It is a high-income city due to its proximity to Washington, D.C. where many federal agencies and offices are located. Its population is only about 147,000 which translate to a population density of approximately 9,400 people per square mile. Its total area is 15.4 square miles (15.2 sq. miles of land and 0.2 sq. miles of water); Alexandria is a very historic place because of the key role it played during the American Civil War. Alexandria was declared an Eco-City in 2008, which means its inhabitants have promised to use the...

...in New York where skyscrapers proliferate just like mushrooms in a rainy season. Seen this way, the level of sacrifice that is poured in by the couple is too much to think about and do. They were living against the norm but they persisted for a cause. It is very humbling to realize that their struggle is not directed towards personal achievement but a witnessing: it was the intention of Beavan and his wife to prove to the world that every person can do something, in his own simple ways, to control the exacerbation of the ecological domain and to mitigate the effects of global warming and climate change. By and large, what makes the documentary more convincing is that they gave up everything to become full-pledged...

...Part What are some environmental impacts seen in rich nations (like our own) A. In rich countries, the populated areas are influenced mostly by production of energy which is advancing at a faster pace. The reason behind lower impacts is that the rich countries take advantage of the deforestation, intensified farming and other factors occurring in the poor nations. What are some environmental impacts seen in poor nations A. The poor nations suffer from climate change, depletion of ozone, deforestation and increase in agriculture which leads to several other problems such as salinity water pollution. The problems get severe is the population is high. Your answers should have been different to the questions above. Why... What are some...

...Introduction to Ecology Warm air has the capability of containing more moisture than cool air hence the less dense air which is low in atmosphere would rise, expand and then cool at 100C for every 1000m as observed by Molles (2009). The cooled air loses the ability to hold any more moisture and condenses to water droplets forming clouds. On the other hand, when it descends, the air warms and dries. The heat from the sun is distributed unevenly across the surface of the earth with tropical and equatorial regions receiving more solar than the polar and mid-latitude regions. Near the equator, the incoming sunlight tends to be vertically inclined to the ground causing greater heating than near the poles where the inclination...

...Social Ecology The passage criticizes the arguments of Holmes Rolston about conserving the environment and responding to the population growth. The author, Robin Attfield contends that preserving the environment is right. However, he differs with arguments of Holmes Rolston on the best way to preserve the ecosystem. Holmes holds that conserving ecosystem should take the first priority over the interest of humans (Attfield 292-297). Holmes feels that people should starve, raise limited children, and preserve vast lands for the natural reserves. In addition, he human beings should not take the first priority over the natural ecosystem (Attfield 292). The arguments of Holmes favor natural ecosystems. However, the author of...

Bacteria
...Bacteria Bacteria Bacteria pathogeni is the process through which bacteria cause the development of diseases on their hosts. Bacteria have different structures that influence their pathogenicity. The three structures that affect the process include the tissue fluid, which helps in their multiplication. Additionally, the flagella help the bacteria in their movements, and the fimbriae that attach them to their hosts. Flagella are the structures made of proteins that look like tails. They allow the bacteria to swim when the motor features in the plasma membrane spin them. They help the bacteria to move away...

Change is a “constant process” happening in an ecosystem caused by natural forces, which include climatic changes,...

There are dangerous bacteria that can make you sick and then there are a number of helpful bacteria that actually contribute to keeping you healthy. There is one particular bacterium, properly called, Vibrio fischeri. This bacterium is defined as a “heterotrophic gram-negative bacteria” that is commonly found in temperate and subtropical waters. In appearance it has an oblong shape with flagella on either end that help it to propel themselves along through their environment. Despite the fact, that their natural habitat is water it is actually inside or on the...
