Beta Fish Analysis

The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

Osmosis took place in the egg under a variety of conditions because the membrane of the egg has tiny openings where water can pass through from high to low concentrations. On day one, it was a hypotonic solution because the higher concentration of water in the vinegar moved to the smaller concentration in the egg. This means the egg was filled with water, which resulted in the eggs increase in size. On day three, the hypotonic solution occurred because the corn syrup had a lower concentration of water than the egg. That means the egg released water into the corn syrup, which resulted in the eggs decrease in size. On day four, the egg was placed in water which resulted in an isotonic solution where the concentrations become even. This

In Graph III, in general the results showed that both the fish in our group and by the class standard had something go wrong as for the warm fish, oxygen consumption should have remained stable over periods

Once the experiment was concluded, aged water was slowly added to the temperature- stressed fish in order to raise the temperature of its water. This helped to return its environment back to normal conditions.

13. Which of the following is not an expected response in a fish to a drop in water temperature?

We placed 50 mL of vinegar, tap water, seawater into three respective beakers. 50 mL of seltzer water was placed into a jar with a lid

The containers were plastic and 18 by 15 by 6 centimeters long. Prior to the experiment being performed, the crickets had spent a week in these residencies. Along with the crickets in the plastic containers, there was wet pieces of paper towel and a slice of carrot.

A male Betta is to be placed on the opposite side of the bowl, so that they can see each other but no contact. The fish were observed for two minutes. After the two minutes passed, the barrier was lifted and observations were recorded for one minute before the male was removed from the bowl. This was then repeated with the female Betta. These two constitute one trial. There was a total of three trials, so both the male and female were in the primary bowl thrice

Radish farms along the Nelson river had a recent lack of growth of their radishes. A landfill and a salt storage facility had recently opened along the river near the farms. Samples from the river were taken and used to grow radishes to see what caused the lack of growth. The salt storage facility had leaked into the river, causing samples B and D not grow.

The whole purpose of this lab is to see how the planaria behave in certain environmental changes and how they can regenerated themselves. The experiments all involved the planaria and placing them in a petri dish with spring water. For each of the taxes, different ways was used to see how they response. For thigmotaxis, a pipet is use to touch the planaria in different spot to see how they would response to it. For phototaxis, a flashlight and a smartphone light was used. For the phone light, there was two different power, low and high. For chemotaxis, liver was used so the planaria can used their eyespots to locate the food. And for rhoetaxis, a pipet was used to make some water current and placing the planaria in the dish to see what their

The water is a medium dark color. The fish is still moving. The plants looked chewed up.

I took the sample pond water from the library pond (Central Michigan University), thinking well during mock rock this year I want to know really what I am swimming in. So I took a jar then scooped it up from the muskiest part of the pond. After collecting the sample we placed the sample in a glass jar in the Biology lab at Mid Michigan Community College by a window and then it was sealed with oxygen holes. We would be checking on the sample once a week for lasting six weeks, just incase we

In order to uncover the conditions which allow for the exploitation of fish in the lagoon, I will examine the issue with a
