Basing our hypothesis off of this past experiment, I hypothesized that in the presence of ammonium nitrate we should see an increased germination rate of our spores from the Ceratopteris richardii. We grew 2 different cultures of the fern spores, one on a control petri dish and one in 1% NH4NO3, with 6 replicates. They were grown for 4 weeks and were put under sufficient lighting. All the data was compiled from all the replicates and after all the calculations we found that there was a significant difference in the spore germination rate. Less germinated in the presence of 1% ammonium nitrate compared to the spores not in the presence of ammonium nitrate.
Then, we performed an f-test and a t-test to determine if there was any germination difference between the treatments. We hypothesized that ammonium nitrate would promote spore germination because past research on Botrychium dissectum revealed that the presence of ammonium on the medium had a positive effect on spore germination (Melan & Whittier 1990). However, in our experiment, the highest germination was observed on the media lacking ammonium nitrate. We calculated a spore germination mean value of 115.83 on the control group compared to 56.33 on the experimental group. We concluded that ammonium nitrate inhibits C. richardii spore germination.
Question: How do different salinities affect a seeds ability to germinate? 2 pt Hypothesis: I hypothesize that the seeds in a lower salinity will germinate more. 2 points Prediction: If seeds are place in a bag with a lower salinity, then they are going to germinate more than those in a higher salinity solution. 2 points Materials: • • 60 red kidney beans solutions of 0.0% salt (tap water), 0.20% salt, 0.6.0% salt, 1.0% salt, 1.5% salt 5 paper napkins New package • • 5 plastic baggies with holes cut in them for
The results showed that the increasing of the density leads to a decrease in the biomass of plants and that the experimental groups are not much different than the control groups. This shows that an environment can work to stabilize itself without human interruptions. Plants can ensure they don’t overpopulate an area by self-thinning and species can survive with predators using the environment they were given. Introduction Competition for resources is seen in all species and environments around the world. Since the Earth’s natural resources are limited, it necessary for species of all kingdoms to fight in order to gain enough nutrients in order to not only live but thrive and go on to produce future generations.
Another important trend was the increasing mechanization of cranberry harvesting and could result in yields up to 20% greater than those obtained via dry harvesting. However, water-harvested berries should be shipped in box that contain only 1/3 bbl of berries because of the risk of damage and it also shorten the time berries stay in fresh. Receiving Plant No. 1 (RP1) RP1 received both fresh fruit and process fruit. The handling of process fruit at RP1 was highly mechanized in many ways.
I need to analyze the types of carbohydrates that I am consuming and make sure that the majority are whole grains and nutrient dense. Protein 14.6% of kCal’s from my intake came from protein and according to the AMDR’s range of 10-35%, my protein intake is on the low side. I have to consume more protein to decrease my disease risk. Some examples of food that I should add to my diet are legumes, fish and skinless poultry. With the help of the Intake Compared to DRI report I was able to identify the nutrients in which I was deficient in during my three day analysis.
This is the same with the orange juice. Sugar can affect plant growth too. Over expressing Arabidopsis in plants reduces growth in plants. Due to hypertonic states of different liquids, some juices and sodas can kill plants. This experiment will look at how soda, juice, and water will affect the growth of plants.
Fiber, also known as roughage, contains many properties that aid our digestion tract, and allow us to process waste products more efficiently. According to Nutrition.gov (2013) fiber can be found in many of our favorite foods including whole grains, vegetables, and fruits. There are two types of fiber, soluble and insoluble. Soluble fibers dissolve in water, and when digested, “form viscous solutions in the intestines” (Grosvenor & Smolin, 2006). “Fibers that cannot be digested by bacteria in the large intestines are called insoluble fibers because they do not dissolve in water.” (Grosvenor & Smolin, 2006) High fiber diets can produce many benefits, including higher nutrient absorption levels, and better waste output.
Consuming the proper amount of macronutrients in your diet is essential for proper health and growth of your body. Proteins are needed to keep the body growing properly and cell growth. Eating too little will cause slow development and eating too many, the body will store the protein as fat. Carbohydrates give the body energy, like eating a snickers bar full of nuts will give the body a boost of energy. Eating the proper amount of carbohydrates will help the body to not store an excess amount of fat.
Fruits and vegetables contain folate, which helps give you more energy and repairs cell damage caused by stress. Nuts and seeds. These contain vitamin E, which enhances your mood and boosts your immune system, as well as omega 3 fats that can help prevent surges in stress hormones. Foods high in magnesium. Too little magnesium in our diet can trigger headaches and fatigue.
