planet and that it is the reason why Earth is not going to be able to sustain us for much longer. Many people believe, however, that the population of the human race isn’t the reason for Earth’s decline in resources. It is, in fact, us. We, as a species, are solely responsible for Earth’s sudden decline in sustainability. It is not how many of us there are, it is how we live and how we produce, consume and waste our many resources. One of the biggest issues in todays world has a lot to do with…

1. The movie Life on Earth focused on how fossils are glimpses of a distant past because they explain how life evolved on earth. They also used a Cladogram to explain the cladistic relationship between a number of species. The first organism with a nucleus lived one and a half million years ago. An animal with a braincase and a beginning of a backbone appeared 500 million years ago. Amniotes were split into two main lineages. One is identified by a hole that evolved in the skull behind the eye…

conservation crime because it affects the aquatic life which can have potential negative effects on us and the environment in the future. The illegal animal trade is a second conservation crime because endangered species are hunted and killed. For example, the black-market trade of species like killing Hawksbill sea…

of the environment(Thompson). Diversity allows for a better ecosystem that improves the world and human life. “Land races have much more genetic diversity” which allows for the different species to adapt better to the world around them(Thompson). Cloning will take away what the diversity does to save the species and continue the evolution of survival in the…

the lice have infested themselves deeper in into the skin. Once you have obtained the hair sample, place it on a slide with the sample down, and proceed to examine it under the microscope (Cellophane Tape Method, 2013). 2) Another situation and species where a cellophane test would be useful is when trying to determine if a horse has pinworms. A louse examination is different…

natural selection by using the finches. The many species of finches all came from one common ancestor. Overtime, they needed to change to survive, so they did. This created many different species of finches. Many people are strong believers that Darwin was wrong and that natural selection is non existent. But, his theory was proven to be one hundred percent true by the Grants who worked to prove this theory for decades. For example, there are thirteen species of finches living in the Galapagos…

overwhelming in size. The Grand Canyon is a 277 mile long and 18 mile deep canyon in Arizona. The Grand Canyon has stood as one of nature’s most impressive sights for many years. The Grand Canyon has many important species of animals. There are 355 bird species, 89 animal species, and 59 reptile species. 6 types of rattle snake roam the canyon. One type is famous for its pinkish color. Park administrators stress the fact that pollution must be stopped in order to preserve all the types of…

An individual within a population with an advantageous trait is more likely to survive than the individual without that trait. This means the species without the advantageous trait have a higher chance of dying and will most likely reduce in number. If the trait is heritable, the individual with the trait will produce offspring with that trait and actively grow in number since the trait allows them to better survive in their environment. This is natural selection. Natural selection is the force…

Introduction Squirrels are small rodents commonly known across the United States. There are over 200 squirrels species. They belong in the genius Scieridae(1). There size is varies from 5 inches to 3 feet long. The commonly known squirrel in Kansas is either the Eastern Fox Squirrel, its recorded size varies from 18-28 inches. The genus name for the Easter Fox Squirrel is Sciurus Niger(2). Animal activity can be measured in the observation of animals in a certain location. The Activity can…

and experiments. For example, they take animals’ blood samples to check their level of nutrition, for disease or even parasites, and they tag animals in order to track them in the wild. Many zoologists and wildlife biologists study specific species. For example,such as evolution and animals behavior (ADD HERE AN EXAMPLE OF A SPECIFIC FIELD). Fieldwork can require zoologist and wildlife biologists to travel to remote locations anywhere in the world…
