Plankton Activity Postlab, Questions And Answers

This value was 0.019589 and with this statistic we were able to look at our hypothesis again. We could successfully conclude that our null hypothesis of the urine having no effect on the mice was wrong. This is because of P-value is <0.05 and represents that are data was statistically

Our dependant variable in this experiment was the dissolved oxygen parts per million in each sample. We recorded this data on the white board back in our classroom, writing down the specific parts per million that we found in the water. The variables that were the same for all

According to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).

Eutrophication is the excessive nutrients in a lake or body of water, frequently due to runoff from the land, which causes a dense growth of a plant life and death of animal life from lack of oxygen. We tested for phosphate, nitrate, and dissolved oxygen. Phosphates and Nitrates are found in fertilizers, laundry detergents, and sewage treatments. Dissolved oxygen is microscopic bubbles of gaseous oxygen that are mixed in water and aailable to aquatic organisms for respiration. We found that there was a phosphate average of 0.1 parts per million (ppm).

Based on my observations I hypothesized that both Herbert Run and the Commons stream would have a high level of nitrate, conductivity, and turbidity. I hypothesized this because of traffic, liter, and the waste and pollution in both streams. For the Commons Stream, the Conductivity was 1086µS/cm. The turbidity was 0 FAU. Last, the Nitrate level for Commons was 0.08 ppm.

The χ2 value was 0.012858, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact reliable. In Trial 3, twelve isopods (60%) made the choices of hiding behind the sucrose sponge. The χ2 value was 0.00350342, df was 3 and hence the P value was in between

Environmental Science and Sustainability (SCI201 -1504A -07) Instructor: Trena Woolridge Unit 4- Discussion Board Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment.

The starting population of the experiment contained 100 organisms that had 10 different Dottus Variengatus phenotypes. A multicolored-city board was used to simulate the environment where these organisms lived. To perform the experiment, groups of three were formed. The first member had to act as a new predator of the population, the second member was assigned to randomly disperse the colored dots on the board, help keep count of the consumed dots, and collect materials at the end of the experiment. The third member had to collect the prey from the predator, and help keep count until 25 dots were collected.

Salinity Changes With Sheepshead Minnows Sheepshead minnows are one of the few fish that can survive in a big change in salinity and temperature. I would like to observe how long they can survive in a certain amount of salinity with small changes in salinity over time. I will slowly over five day period, take away salt from the sheepshead minnows tank. I will have twenty sheepshead minnows in all, ten in the tank having the salt removed and another ten in a tank with the same salinity as the water I found them in. This is important because we can learn how some animals adapt over time to live in different environments.

Quinn Nguyen Floating Leaf Disk Photosynthesis Lab Conclusion: Graph your results for all 3 trials on one graph. Label the graph, both axes, and provide a legend to distinguish each trial. What was the rate of photosynthesis for each variable? How many leaves floated per minute? Rate of photosynthesis (leaves/min) Spinach: (2-0)/25 = 0.08

In this ecosystem, the larger area will have a greater number of species, the smaller

Recently, butts have been all the rage. We easily see Kardashian butts, Bey Butts, JLo Butts, Minaj Butts everywhere. So, more butts the better, right? A friend just told me (let’s call him Gordon) about a sea worm with endless butts.

1. Bycatch is the marine life that is caught by commercial fishers due to their harmful fishing techniques that were not meant to be caught and are then thrown away. Their techniques include, but are not limited to trawling, long lines, and purse seine nets. 2. The article goes in depth on how one form of sea life, sea turtles, is greatly affected by commercial fishing.

Marine organisms are animals, plants, and other living things that live in the ocean. A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment. To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales.

A question that many wonder about is why is phytoplankton important? Plankton is revealed by ocean color and help show scientists where ocean currents provide nutrients for plant growth. They also help show where pollutants are poisoning the ocean preventing plant growth and where changes in the climate of the ocean are occurring. Plankton is also the foundation of the oceans food chain. As phytoplankton begin to grow and multiply, small fish eat them, then the larger animals begin to eat those smaller animals.
