Invasive Species: Asian Carp Asian carps are different species of fish that originated in many parts of Eurasia. There are 4 different types of Asian carps‚ but the silver carp and bighead carp are mostly found in the Mississippi River drainage basin and Illinois River. The silver and bighead carp first came to North America from China in 1973. Being filter feeders‚ they were imported to remove algae and suspended matter‚ ultimately trying to improve water qualities in aquaculture ponds. However

Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

Module Three: Lab Questions Your first lab link can be found at What is Positive Parenting? A written transcript is also available for this lab. How is positive parenting different from negative parenting? Which do you think is more effective? Why? it’s easy to distinguish negative from positive parenting because parents that use negative parenting skills are usually shouting and yelling and saying a few if you do that again you will get whatever‚ I think positive parenting is more effective

Endangered species are those considered to be at risk of extinction‚ meaning that there are so few left of their kind that they could disappear from the planet altogether. Endangered species are threatened by factors such as habitat loss‚ hunting‚ disease and climate change‚ and usually‚ endangered species‚ have a declining population or a very limited range. The current rate of extinction is thought to be far greater than the expected natural rate‚ with many species going extinct before they have

A lab experiment is a method of research that enables the researcher to control the environment. It is a way of doing a research in a controlled environment on a certain behaviour which will have a cause and effect. It is done in a controlled environment so that extraneous variables are prevented from affecting the results. Behaviourists use lab experiments because they are interested in a cause and effect of certain behaviours. The aim is to control all relevant variables except for one key variable

Biodiversity has been on the decline over the past century and the background rate has been mostly accelerated by the humans. Considerable damage has already been done. Possible solutions have been discussed and categorising species according to how in danger they are is one of those solutions. Below are some of the threatened organisms in different continents around the world. TABLE OF CONTENTS Africa Mammals Birds Reptiles Amphibians Fishes Asia Mammals Birds Reptiles

3/22/2013 Lab 1- The scientific method In this lab I am learning about the steps of the scientific method and how it can be applied to daily life. In my first exercise I analyzed data presented to me in a table (table 2) on fish population in relation to the amount of dissolved oxygen ( ppm ) in the water. The patterns indicate that when more dissolved oxygen (ppm) is present in the water‚ the number of fish observed increases. In developing a hypothesis for this theory‚ I have decided that if
