Extinction is the ceasing of a species to exist on this Earth. A species officially becomes extinct when all of the species no longer exists. A species is to become certainly extinct when there is an extremely small number of it and it is unable to reproduce to create more of itself. Therefore‚ we say a species is in for certain extinction if it cannot reproduce itself. Extinctions occur at a great pace and species that we did not even know existed become extinct all the time. Scientists say that

Should Anyone Say Forever? Page 70 Chapter VI The Mystery of Fidelity The problem with commitments is not so much making them‚ but keeping them. Judging by human behavior‚ at least‚ that must be the harder part. So our subject matter for this chapter moves from commitment to the question of fidelity. First we will inquire into how fidelity and commitment are related‚ then we will analyze the components of fidelity‚ and finally we will attempt to situate human fidelity in its religious and theological

is impossible to say that fashion is not important. It is important anyway because everyone follows fashion. It concerns not only clothes‚ but the way do some things‚ the way we behave and so on. On the other hand‚ some people claim‚ that fashion is not important because it is constantly changing and rehashing all of the things that have already been done. Besides‚ people can judge you on fashion and your appearance and this is not a good idea. I strongly disagree with this point of view because

The Sixth Extinction According to the information given by Niles Eldredge‚ about 30‚000 species go extinct annually. The first five major extinctions that have happened in the past were due to natural causes. The first started with severe and sudden global cooling and lost 25% of families. The second happened near the end of the Devonian Period and may or may not have been the result of a global climate change of which 19% of families were lost. Evidence suggests that a bolide impact similar

De-Extinction is one of the hottest topics in the science world currently and it tops the lists of conservation and genetic scientists alike for next big project. Though this could be a great way to learn of past species and finally see them for ourselves‚ at what cost is a species revived? The idea of bringing back an extinct species‚ such as some type of dinosaur‚ comes with many questions that most find to be debatable. Conflicts arise from every aspect of this “new” animal including how it is

similarities between plant and animal cells are as follows: 1. Both are constructed from eukaryotic cells. 2. Both contain a defined nucleus. 3. Both have mitochondria. 4. Both have Golgi bodies. 5. Both are surrounded by a cell membrane. Three differences are: 1. Plants cells have a cell wall‚ whereas animal cells do not. 2. Animal cells have lysosomes‚ whereas plant cells do not. 3. Animal cells contain centrioles and a cytoskeleton‚ whereas most plants do not. Five

Plant and animal cells have several differences and similarities. For example‚ animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes. Animal Cell Plant Cell Cell wall Absent Present (formed of cellulose) Shape Round (irregular shape) Rectangular (fixed shape) Vacuole One or more small vacuoles (much smaller than plant cells).

of Animal and Plant Cells Instructions: 1. Set up light microscope for use. Handle with care. 2. Obtain a slide of animal cells and observe first under low-power (4X)‚ then under medium power (10X)‚ then finally switch to high-power (40X). 3. Make careful observations of the structure of the cells. 4. Draw what you see under high power on a sheet of paper. Place your drawing in a circle measuring 10-15 cm. Use only pencil‚ draw neat lines‚ do not shade. The title of the drawing should be beneath
