One World Essay:

As I started the Essay, I was confident about my works. Since population growth subject was a common title for me, I didn't struggle too much. Until I got to the bibliography source part I was on the right track. After handing in, I founded that the bibliography wasn't in the right format. Besides the bibliography part, I was satisfied about what I worked on. By Studing the differences between human population growth and the animals, I could find the unlike changes for both of them. After researching the patterns of the populations, the majority workers in the systems were niche: Predators and Preys. I investigated the limiters of the actual populations combining Economists and Biologists thoughts. The examples are

1.Loss of Population due to predation
2.Parasite diseases creating disasters
3.Handiness of water and nutrition

Also, animal populations alternate over time due to births, deaths, and the distributions of individuals between separate populations. When resources are plentiful and environmental conditions appropriate, populations can increase rapidly. For humans successful agriculture revolutions and developed cultures tied can lead surges to population growths. All these information can be the issues of population growths within learning about these issues, we can all think again to appreciate our ancestors for developing cultures, populations, habitats etc.

Lab Report:

By determining and investigating the plant, Phillip and I needed more time and more efficient works. I regret the impetuous works we finished in a short time. The interval of this project was the main importance of ours but we didn’t use the time. I think that the behavioral and the structural adaptations among the plants caused a huge difference than my expectations were. I anticipated to discover the negatives and fatal situations of plants but...
Answering to the guiding question, some organisms need abiotic factors to survive, if not some will be dead soon and some won’t. They just can’t live in a dark side where there are no resources for them. The solution suggests that there were some symbiotic relationship between soils and the plant. One of them had mutualism which both of the factors benefit and one of them had parasitism.
By looking at others and ours, our plant needed more abiotic factors in-ordered to develop their structures. Since we didn't really care, the plant passed away however it doesn't mean we never appreciated it. The others used all kind of factors to save the plant but I don't think we did. And until then,I need to observe the appearances of both plants.
Everything got mixed up as soon someone added the bean into our plant.

As much as humble bees like to work, they have a new career but they aren’t just making honey; they are trained to tell the evidences of drugs and explosive materials. By being the sniffer bees, honeybee (Apis Mellifera) can be the solution for UK’s answer towards the “Combat National Security” investigating drugs and threats. Since Honey bees have precise and acute olfactory senses, they can be thought as sensitive creatures. By using this kind of techniques, the bees can associate odor with a prize. Many Britain scientists train this species to detect the odors. Odors if you haven’t notice are smells or reaction caused by chemical compounds. The developed technology that UK formed has been upgraded by Inscentinel Ltd, a company based at Rothamsted Research. The group studies potential applications such as detection of drugs and materials which are very explosive. According to their information, bees can detect the harms in airport and the military as well as detecting food quality control. Dr Nesbit, a scientists at Inscentinel Ltd responses that “Bees are at least as good as sniffer dogs but are cheaper and faster to train, and available in much larger numbers.”

While training the honey bees, scientists show them to learn and memories. They are loaded in the separate holders where they sit comfortably and exposed to an odor which passes over them in short pulses. When exposing, the bees are given a drop of sugar syrup which they stick their tongue out to receive, the experiment concludes the first term that it is a classical “Pavlovian” conditioning method. The whole training (two and eight rounds) completes in few hours and reflexes lasting for days. While the experiment occurs, scientists tell the proboscis of each bee sticking out to anticipate receiving rewards. The proboscis gives a “signal that the scientists use to determine successful conditioning.” When records come out, the scientists determine to find records. The detecting experiments last for 6 seconds. We now know that instead of sniffing wild dogs, we can use stinging calm bees instead.

Population Growth (Animals/ bit of Human)

As you know there are more species than you can count in 10 seconds. In ecosystem, there are varieties of species which are different sizes, different shapes, and is located in different positions etc. Animal populations alter over time because of births, fatal deaths, and scattering of individuals between separate populations. When there are plentiful resources and appropriate environmental conditions, populations can upsurge rapidly. Many abiotic causes can damage the environment for example drought, hurricane, floods etc often disturb population growth. Those non-living factors can limit the population to a lower level than before. The change of the population is now a problem and influence to the biosphere. In the animal living system, there are additional niche, for instance preys and predators. Predators must need to consume preys in-order to live, if the amounts of preys decrease than predators will die out. Including the factors in the ecosystem, the changes of the population occurs.

Human population/Animal Consumption

A) Stories of animal population growths/Decay and discussions…

In present, well known Economists disagree and points the mistakes from the biologists that didn't come true to justify their position. Economists recall that population can get up to “Market Forces” which will/can be a huge impact to the population in the future. The statement was genuine and persuasive to the audiences however this was the start of the controversial issues. On the other hand, Biologists say that “We have run out of resources in the past and have always found something else to replace them.” We have seen that economists are looking beyond the quality of life issue and the biologists are going in-depth towards the topic and the terms. These are the noticeable issues for all organisms must deal about. In addition, the number of animals living in domestic mutualism has increases throughout the Decades; large domestic animals are about 1.7 billion sheep and goats, 1.3 billion cows, and 0.3 billion horses, camels, and water buffalos. People in present are accompanied by a bunch of animal species including 10-11 billion chickens. Those companions support the ecosystem of living to perform a huge increase of population.
As the increase of population started there became additional outcomes and influences, as more people live in earth, there will be more Sunlight-Producer-1st, 2nd 3rd consumer-Decomposer cycle. People will have to consume more of other organisms, if it’s balanced it is quite well but if there isn’t plenty of nutrition then we will have no choice. Population is increase in the number of people who dwells at territories or state. If human disturbances of harsh treatment towards a certain species occur then a decrease of the organisms will happen. If human pollutes the ocean and the organisms in water die out, we won’t have any marine products to consume. It is lose-lose situation, to prevent this we should always care about the environment. When there is lose-lose situations, the culprits will directly be us since we are the causes to everything. Study declared today tells that deliberating the population growth would save animals and reduce greenhouse gas radiations by approximately 1/3 of the amount needed to avoid devastating climate change. In current, there are 6.9 billion people on the planet, and by 2050, the biosphere will contain 9 billion people. Human overpopulation is a major problem which will affect the animals because it leads directly to “deforestation, desertification, climate change, pollution and varieties of other problems that kill and relocate the wild lives,” not to mention the direct slaughter of animals for food.

The limiters of the actual populations combining Economists and Biologists thoughts are
1. Loss of Population due to predation
2. Parasite diseases creating disasters
3. Handiness of water and nutrition
Beyond disruptions could come in form of

1. Temperature causes
2. Disruption of species breeding, nesting
B) Story of Hominids/Human population growths
For almost all of that history, a tiny population was engaged in a subsistence lifestyle, including the old life styles and the hunting. The global population during the time was less than million people however the outcomes of the discoveries of crude tools, hunting tools or weapons, setting the techniques up and spreading them etc allowed prehistoric hominids to go beyond their environment, which was the starting session of increasing the population. About ten thousand years ago, hominids found primitive agriculture through the domestication of organism species and plant factors, also the ways of promoting the lands. Early cultural human system of carrying capacity made a population towards peoples’ view. These logical reasons resulted the population growth due to ancient agricultural system. Besides hunting and looking for nutrition, planting was one of the starts of developing the population of organisms.
Chart explaining the growth of human population
As I read through the information needed to write this 700minimum-1400 maximum one world essay, I’ve notice alters between human and animals. When I found the article, “Slowing Human Population Growth Would Save Animals,” I was exhausted due to the topic sentence commenting that increasing population is not the right thing to do. It can be a topic to consider about because by looking at the topic we can learn the mistakes we have made. This topic “Population Growth” can be connected to other topics, population growth or decay can be the effect of the causes what humans have done. Besides knowing the facts and global population, I’ve figured the situations where population growth can affect them.

Current Event 3 "How the Penguin changed its feathers"

How the Penguin changed its feathers

In a small region in Peru, paleontologist have discovered the importance of 36 million old ancient feather fossil followed by different color and pattern scheme, the paleontologist concluded as declaring, "the ancient fossils suggest that the feather of the primitive penguins weren't hardy as now it used to be." The ancient fossil was investigated and first discovered by a Peruvian student (Ali Altamirano) and was found in Paracas National Reserve on the Peruvian coast south of the capital "Lima".When researchers noticed that there was scaly smooth tissue protected/preserved on an exposed foot, they named/nicknamed it the specimen "Pedro," after a sleazy, scaly character from a Colombian soap opera. Rather than classical/modern penguins we usually see today, the ancient ones were colorful and contained reddish - brown and gray feathers. The name of the fossil species " Inkayacu Paracasensis" meant as the Water King of Paracas in the Quecha Language. The Inkayacu paracasensis skeleton suggests how primitive penguins adapted their surroundings.When paleontologists analyzed the creature's height, they estimated that it was nearly around 5 feet such as Emperor Penguin.

Besides preserved fossils of flippers and feathers there are additional fine patterns of color-producing nanostructures known as melanosomes that has to be kept. Patterns could be contrast with a vast database of melanosome structures for living birds.
Melanosomes are biological cell, is an organelle which contains a melanin. The shapes of the feathers and the flippers were close to what is seen in penguins today. However patterns of the fossilized melanosomes are less similar to today’s penguins but they are inclose touch with aquatic birds. Modern-day penguins have giant melanosomes that are broader than the ancient ones.In fact, today's penguins have bigger melanosomes than the ones found in all kinds of bird species.The fact that penguins initially adapted to their aquatic environment was by developing strong, feathers that were stacked to make stiff, and narrow flippers.

Scientists and paleontologists believe that alternation of color might have been a side effect of the shift in melanosome structure, or caused due to protective response to relatively recent predators such as leopard seals. One of the co-authors responses that "Insights into the color of extinct organisms can reveal clues to their ecology and behavior." "But most of all, I think it is simply just cool to get a look at the color of a remarkable extinct organism, such as a giant fossil penguin."
