the seed is triggered by water to sprout‚ a process called germination begins. Germination refers to the sprouting of a fungal seed or‚ more commonly‚ an angiosperm or gymnosperm plant. The process ends when a shoot emerges from the seed. This lab tests whether the germination of a radish seed is affected by the amount of light it receives. One control group is set in a room that will have normal light conditions‚ while the other experimental group is placed in a dark room without light. Ten seeds

This lab tests the process of germination with various pH levels. The pH level of something is its measure of acidity or how basic it is‚ solutions with a pH of less than 7 are said to be acidic‚ and solutions with a pH greater than 7 are said to be basic. The tap water that was used to water our beans had a pH of 6. In this lab‚ we studied the process of germination (the process by which a plant grows from a seed). Certain environmental factors can cause or stop a seed’s germination‚ and these factors

Lab Questions: Are flame tests valuable for detecting metal ions present in a mixture of metal ions? Flame test may not be valuable for detecting individual metal ions present in a mixture of metal ions. Although each metal ion emits a different color of light‚ which corresponds to a certain wavelength of light‚ the

condition (listed from left to right in the table) ranged from: 19.6-59.2%‚ 11.8-76.0%‚ 25.0-92.3%‚ and 12.5-89.8%‚ respectively. From this‚ we can generally see how the data from each group is spread out across each ligation condition. Table 2. ANOVA test results. The p-value corresponding to the F-statistic is lower than 0.05‚ suggesting that one or more treatments are significantly different. We can see that the treatments that are significantly different are the 1:1 with stuffer and 2:1 without stuffer

Background In the Flame test lab we took a simple wire‚ looped it‚ and rinsed it in HCL (Hydrochloric Acid ). Then we dipped the wire in the different samples provided. The samples provided were Sodium‚Potassium‚Calcium‚ Barium‚ Strontium‚ Lithium ‚ and Copper II. Finally we put the wire loop into the flame of the bunsen burner. The flame erupted into many different colors for each specific sample. We then used the colors we recorded to find the two unknown samples given to us. But the question

Biochemistry Exam I Terminology Boiling point is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid. At this temperature the liquid phase changes into the gaseous phase (also a colligative property) Melting point is the temperature at which the solid and liquid phases are in equilibrium. At this temperature the solid state changes into a liquid phase (also a colligative property) Specific heat is the amount of energy (in joules or calories) needed

After conducting the trials for each beaker and each bag my hypothesis of each of the trials were correct. Every outcome I predicted occurred to each beaker and each bag. Beakers 1 and 2 decreased in mass while beaker 3 stayed constant. Beaker 4 actually increased in mass as well. Bags 1 and 2 increased in mass while bag 3 stayed the same. Bag 4 resulted in a decrease in mass. The results I got from this experiment do support what I predicted before the trials. Above you can see a specimen of an
