Controversy exists over whether biodiversity issues have negative impacts on the ecosystem and environment. While some well-intentioned people believe that the environment would not be affected by biodiversity (biological diversity) problems, I hold onto the view that biodiversity issues strongly influence ecosystems in that they not only effect on the land, but also will create significant challenges for the air and the water resources. Biodiversity is commonly defined as the variety of all…

Immune System(Remove) What does immune system means? The immune system is the one of necessity system in the body. It helps the body defend against every foreign body that causes disease for body. The immune system is getting stronger and stronger while it destroys disease. It takes experience from disease which it is destroyed. The immune system is defined as “the system that protects your body from diseases and infections” in Merriam-Webster dictionary. In other words, the immune system…

The external features of a lion help them survive in their habitat. Both females and males have a golden tan color that help them camouflage to their surroundings. However, there does exist a white variant which appears once in awhile in some lions. There is a huge external difference that separates males and females which is the male's mane. The mane is large and bushy, and it stretches all the way from the neck to the beginning of its back. It also gets darker as the lion ages. The lion has…

Chapter One: The author grew up in Kenya, a place which developed his love of nature and all the flora and fauna within it and provided a chance for that love to grow. His parents were both passionate naturalists, especially his father. He was taught to love fossils because of his parents love for them. Because of being raised in the wild, he has always been drawn to it. When he was younger, he would sell bones to museums. This job helped him to prepare for his future specialty in…

receptor. Both of these are members of receptor tyrosine kinase (RTK) class II. The primary and unique effects of the hormone take place through IGF1R, which, when activated, triggers a chemical sequence called the AKT pathway. This process, revolving around a protein called AKT, has significant effects on the life and death of the cell. iii. A chemical resemblance to insulin also allows IGF-1 to active the insulin receptor. This protein triggers a process that ultimately causes a cell to take…

with the knowledge that 35 of 5,513 known mammal species have gone extinct since 1900, we can calculate that mammal species have gone extinct at the rate of 28 faster than it should have. If one factors in the numbers of animals extinct in nature, vertebrates (such as birds, reptiles, amphibians and fish), one finds that the extinction rate of the 20th century is 53 times higher than the baseline extinction rate. But the numbers I have given is only in a smaller scale that allows people better…

Species Extinction: A Pathway to the Sixth Extinction We have all played a game of Jenga, each player removes one block per turn and either the tower will remain upright, or it will all tumble down. This Hasbro game is an exceptional example of the sixth extinction. Simply imagine each block as a different species. Humans are on top while other species like rhinos, polar bears and lions are on the bottom. If one is removed off of the bottom there is a possibility of all of them toppling over,…

Order Hymenoptera, the third-largest order of insects, comprises the sawflies, wasps, bees, and ants. Over 150,000 species are recognized (Janke 2), with many more remaining to be described. Many factors have led to this order’s success, through the development of wings, their immense range of behavioral adaptation, and namely: their highly complex ways of self-defense, mainly those of the biochemical and morphological nature. From the famous “cow-killer” to the range of stings of the Vespidae,…

As a federal agency, NINDS must heed federal legislative mandates and statutory provisions liming the use of funds on NIH awards. Considering NIH is funded by tax dollars, many of the limitations are not surprising: anti-lobbying, limitation of use of funds for promotion of legalization of controlled substances, etc. and some appear to be dictated by policy such as gun control, restrictions on abortions, and restriction on distribution of sterile needles. The apparently less impactful…

The debate to be evaluated at hand is one that included two renown figures who are well respected in their fields of study. Involved in this meticulous debate was the mechanical engineer and science educator Dr. Bill Nye, along with Christian fundamentalist and young earth creationist Dr. Ken Ham. Dr. Ham believes that creation is a viable model of origins in today’s modern scientific era. Young earth creationist and professor of Biomimetic and Engineering at University of Bristol Stuart Burgess…
