Causes of Variation. Variation is a result that leads to a difference or deviation (for example‚ structure‚ form‚ function) from the recognised norm or standard. It is a modification in structure‚ form or function in an organism‚ deviating from other organisms of the same species or group. There are two types of variation: interspecific variation and intraspecific variation. Interspecific variation is when one species differs from another like mammals differ from fish. These differences are explained

Over the past few centuries scientists have been trying to answer the question: what was the origin of life? There have been a number of scientists who have produces a number of plausible theories. The currently most excepted theory is Oparin’s theory‚ which states that the "origin of life on Earth was in nonliving chemical substances which spontaneously formed in Earth’s early atmosphere and combined to make more complex chemicals until living cells were formed. " This maybe a possibility because

understanding of how these types of regeneration occur. During their trials‚ Child and Morgan were able to determine many factors that play a role in the success or failure of regeneration in flatworms. Their main goal‚ however‚ was to find how the organisms encode the information that specifies what part should be regenerated. Even with their extensive research we still don’t have an exact answer to

MONERA • • • • • There are many different kinds of bacteria‚ but all of them belong to the kingdom Monera. A thousand bacteria can sit side by side in just 1 tiny millimeter. Despite their small size‚ bacteria are the most abundant of any organisms on Earth. Bacteria often get a bad reputation because they usually cause illness. Some bacteria doesn’t cause any harm‚ however some are beneficial.

that living organisms share a universal genetic code? -When scientists say that living organisms share a universal genetic code‚ they mean that they share similar amino acids in their genetic sequence‚ to a certain extent. There are changes in the code but they are still similar to a point. How does a universal genetic code relate to the hypotheses about the origin of life on Earth? -A universal genetic code applies to the hypotheses about the origin of life because even though organisms are physically

According to many sources and credited opinions genetically engineering is scientifically dangerous and wrong. Genetic engineering is basically swapping‚ switching and getting rid of certain genes before creating a problemless child. Considering the parents choose to engineer their child the process would include extensive processes to inquiry the child’s natural genes. The many time consuming expensive tests would need to be done to make it possible to know which genes would be faulty in the child

I. Title Laboratory 11. Animal Behavior II. Purpose The purpose of the animal behavior lab was to understand the concept of distributing organisms in a resource gradient. This lab was also made to help us differentiate between kinesis and taxis. After completing the animal behavior lab‚ we should be able to describe aspects of animal behavior as far as its orientation behavior‚ agonistic behavior‚ dominance display‚ and the way it mates or who it chooses to mate with. We should also understand
