haploid of chromosomes. This is because the chromosomes of a female and male sex cell merge when the female egg is fertilized and thus the new cell (formed through fertilization) will have a diploid of chromosomes from which to build upon as the new organism develops. DNA duplication is also confused as occurring in both Mitosis and Meiosis. In one regard‚ this assumption is correct. However‚ this correctness requires that a person specify at which stage of meiosis DNA duplication occurs. DNA duplication

Explain the statement: "Without autotrophic organisms‚ heterotrophic lofe would cease to exist." Without autotrophic organisms heterotrophic organisms would not be able to survive for two asic reasons. One is the fact that autotrophic organisms create most of the oxygen that heterotrophs breath. Whithout them‚ heterotrophs which need oxygen to survive would not live very long. The second reason

Z.B ‚Pan No. ALUPA2607A Why do we associate such visible movements with life? A possible answer is that we think of movement as a response to a change in the environment of the organism. The cat may be running because it has seen a mouse. Not only that‚ we also think of movement as an attempt by living organisms to use changes in their environment to their advantage. Plants grow out into the sunshine. Children try to get pleasure and fun out of swinging. Buffaloes chew cud to help break up

Organisms have complex and extraordinary tools for sensing their environments. These tools have been honed to enable them to efficiently navigate the world around them. As a result‚ each and every organism alive today is the product of natural selection. Over time‚ this acquired set of skills evolved into the five common senses; sight‚ smell‚ touch‚ hearing‚ and taste. Taste is one of the most valuable ways an organism can interact with its environment‚ since the ability to identify and process the

Analytical Brief - Cloning Cloning is the process of creating copies of DNA‚ cells‚ or organisms‚ in other words‚ it is the “creation of an organism that is an exact copy of another” (What is Cloning?). An early embryo cell is separated in a petri dish and injected into a surrogate mother. Through cloning‚ scientists are able to make an exact genetic copy of a living organism. The clone and the original are identical in every way. Clones are able to function and interact with other living things

All living things have evolved into three groups‚ or domains‚ of closely related organisms: Archaea‚ Bacteria‚ and Eukaryota. Archaea and Bacteria are small‚ simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic

living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce‚ that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process‚ whether asexual or sexual always involves an exchange in hereditary material from the parents so that the new organism may also be able to

However‚ genetically modified organisms and products awaken apprehension regarding their affect on people’s health and the environment. There are therefore laws that regulate the use and exposure of these organisms. In the European Union there was a five-year moratorium on the approval of new genetically modified crops‚ which ended in May 2004 when type Bt-11 corn was
