2. After planting the seed variety, select the level of ECB infestation that will be introduced into each chamber. 3. Allow the seeds to grow for 140 days. 4.
The molecular basis of the smooth (alleles: SS or Ss) and wrinkled (alleles: ss) pea seeds involves the gene that codes for the enzyme phosphorylase. Peas that inherited the genotype “ss” (wrinkled peas) have an inactive form of the enzyme. Peas that are Ss have smaller amounts of the enzyme than SS seeds (not necessarily true because it is
Findings intriguing, Kaffka , factors confound the results: soil types could be moisture or irrigation ,the variety of tomatoes Few rigorous studies that have compared organic conventional mixed results. No consistent evidence lead to more healthful foods. So Kaffka skeptical. B. Locally grown food, healthier food choices.
Biology Unit 6: Investigating tomato inhibitors on the germination of seeds Abstract The aim of this investigation is to investigate the effect of different germination inhibitors of tomato on seeds. A number of tomato seeds from tomatoes of the same variety were extracted and placed in a petri dish with cotton wool. With the use of tomato germination inhibitors like tomato juice, high level of sugar and gel coat, I was able to measure the percentage germination of the seeds. The results obtained showed that the gel coat that is found around each tomato seed and the tomato juice itself act as germination inhibitors resulting to the non-germination of the tomato seeds; agreeing with the experimental hypothesis. The t-test was used to show the statistical significance between the germination inhibitors and germination of seeds.
He named the resulting substance Penicillin, and 5 years later it became the first usable antibiotic. Penicillin is produced by a group of fungi of the Penicillium genus. Streptomycin was the next widely used antibiotic, developed from a soil dwelling bacterium. This antibiotic is very useful for treating streptococcus infections and is even effective against tuberculosis. Several more antibiotic were developed in the years following and many emerged in the 1950s and 1960s.
Innate behavior is an unlearned, inherited fixed action pattern, while learned behavior is not inherited but gradually ascertained throughout the life span of a species. Methods and Materials Seven experimental apparatus’ were constructed, like the one in figure 1. Two petri dishes were cut so as to be connected at one end then glued together on a small portion of wood blocking. The petri dishes simulate the testing environment and the connected end allows the specimens to move freely in between scenarios. First the phototaxis experiment was conducted by placing five Armadillidium vulgare in each side of the petri dish for a total of ten in the overall created environment.
HOW SUCROSE OF DIFFERENT CONCENTRATION AFFECT APPLE AND POTATO DURING OSMOSIS DATE OF EXPERIMENT: 14/11/2014 DUE DATE: TUE.25/11/2014 SUBJECT: BIOLOGY HL NAME: ANIMAM MADELIN NATALE ZINGISI Aim: (i) To determine the concentration of the sucrose solution that has the same water potential as that of the plant cells used. (ii) To compare the water potential of the potato and apple cells. The table.1 showing apple data Concentration of sucrose in Moles | Mass before(±0.002)g | Mass after(±0.004)g | Mass gained or Lost g | % change | Distilled water | 0.870 | 0.924 | 0.054 | 6.21% | 0.2 | 0.924 | 0.996 | 0.072 | 7.79% | 0.4 | 0.898 | 0.960 | 0.062 | 6.90% | 0.6 | 0.942 | 0.980 | 0.038 | 4.03% | 0.8 | 0.988 | 0.962 | -0.026 | -2.63% | 1.0 | 0.878 | 0.822 | -0.056 | -6.38% | Table .1 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Table 2.Potato Data and calculation | | | | | | | | | | | | | | | | | | | | | | | Conc of Sucrose in M | Mass before(±0.002)g | Mass after(±0.004)g | Mass gained or Lost g | % Change | 0 | 1.122 | 1.204 | 0.082 | 7.31% | | 0.2 | 1.215 | 1.216 | 0.001 | ± ± 0.08% | | 0.4 | 1.208 | 1.193 | -0.015 | ± ± -1.24% | | 0.6 | 1.201 | 1.123 | -0.078 | ± ± -6.49% | | 0.8 | 1.066 | 0.958 | -0.108 | ± ± -10.13% | | 1.0 | 1.151 | 0.965 | -0.186 | ± ± -16.16% | | | | | | | | | | | | | | | | | | | | | QUALITATIVE DATA and hypothesis In distilled water (0.0M), 0.2M, 0.4M; All the apples were floating while the potatoes were not. In the other concentrations of (0.6, 0.8, 1.0)M, all the chopped apples and the potatoes were floating. In distilled water, both the apple and potato cylinder was growing in size faster and this was because of higher water potential
Purpose and Hypothesis The purpose of this experiment is to discover mung bean plant growth habits in crowded, or no crowded areas. My hypothesis is that if there are a lot of mung beans in one cup, then the plants will not flourish (as well) due to the fact that they will be fighting for space, nutrients and sunlight. III. Materials 1. 4 paper cups 2.
It is found in dairy products, almonds, avocados, lima beans, peanuts, and seeds. Phenylalanine’s first written description of it was seen in the year 1879 by Schulze and Barbieri. Schulze and Barbieri proposed the empirical formula C9H11NO2. They identified it in yellow lupine seedlings. Three years later Erlenmeyer and Lipp were first to synthesize phenylalanine from phenlacetaldehyde, hydrogen
