Coli since it is a fact that these organism have some form of movement effected by amoeboid movement.Radish seeds grown in water acted as a control in this experiment since water have a near neutral pH of 7. However baking soda was the alkaline solution whereas vinegar served as the acidic solution. It was observed that seeds grown in baking soda solution demonstrated slow growth as compared to those grown in vinegar, a slightly acidic solution. This demonstrates that radish seeds may tolerate

Lactic acid and ethanol Fermentation. (microbiology)
The presence of CO2, released as the waste product is responsible for its foam like expansion as it forms bubbles in the dough. Ethanol, on the other hand evaporates from the dough completely after the bread is fully baked (Kratz, 2005). Ethanol fermentation that is carried out by yeast is employed for the production of nearly all beverages containing alcohol except for those produced by maceration of carbon. In addition, the production of wines and brandies is carried out by the process

Lab Report about primula
The pollen morphology of all species has been previously investigated, but there are no surveys related to the Primula vulgaris species have ever been found. This argument provides that only a close investigation of the Primula vulgaris would provide a better understanding of the reproductive biology of the species reproduction biology. With regard to this species, most of its flowering plants have been found to be hermaphrodite whereby they contain both the male and female reproductive organs.

Lab dispersal time
In this case, an earthworm is the facilitator species. The facilitator species activity has a substantial impact on the soil seed bank dynamics and hence on the possibility of plant recruitment in an ecosystem at large (Allessio, Thomas, & Simpson, 2012).Milkweed, buckthorn, sumac and burdock seeds have different morphological features; Milkweed (Asclepias spp.) seeds are shiny, silky seeds which have snow- white fluffs. They are contained in con-shaped seedpods which crack open when dry to

Lactase Enzyme Activity
Based on my knowledge of the effects of temperature and pH on the enzymatic activity of lactase, if the lactase used in today’s lab was extracted from human cells, I hypothesize that lactase enzyme activity will be optimal at temperature and pH of 400C and 8 respectively.
