Introduction Transpiration is a process which is similar to the evaporation. Water is lost at the surface of the plant such as leaves‚ stems‚ roots and flowers in the form of water vapor. It creates a pulling. Force which causes continuous upward movement of water and mineral salts and this force is called transpiration pull. Apart from to water‚ gas like carbon dioxides from the air can also pass through by the pore of the surface of the plants for photosynthesis. But in this experiment‚ we

In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment

Economic development’s effect on demography Demographic behaviour is a measure of a combination of figures in which indicates how a country’s or region’s population is distributed. The effect of demographic behaviour is that it reflects a country’s stage of economic development to a great extent‚ allowing indication of how far along the Demographic Transition Model (and hence how developed) they are. One measurement of a country’s demographics are by measuring the birth rate (how many live babies

The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

ASU BIO 100 Exam 4 Practice Questions 1. Because of evolutionary descent‚ many species share characteristics with other species to which they are related. Indeed‚ according to evolutionary theory‚ all living species are descended from some common ancestor in the ancient past. What evidence supports this conclusion that ALL living species are related to each other? Shared traits in the fossil record; Genetic Code; DNA Structure of all living organisms 2. For some time‚ Russian prisons have been

b 1 Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally

Hypothesis 1: It was hypothesized that the growth and seed pod production in the standard plants would increase when less competitors were present and that growth would be more affected by competition than seed pod production would be. The data in Figure 1 and Figure 2 support this hypothesis; the standard plant grew the most when it was in a container alone and‚ on average‚ produced more seeds when no competitors were present (Figure 1). Though growth and seed pod production had similar trends

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica
