constant it is important to make sure that the same surrounding are used for the experiment. Surface area. The surface area of the beta vulgaris is another important factor as the greater the surface area of the beta vulgaris‚ the greater the concentration of pigment molecules the beta vulgaris will hold. It is therefore important that all the pieces of beta vulgaris used be of the same length and diameter. Light intensity. It is important that the investigation is carried out in the same light intensity

moschata)‚ beet (Beta vulgaris)‚ and pepper (Capsicum annuum) are all dicot plants‚ which mean that they have two seed leaves inside the seed coat. When they are placed in an environment and are watered with solutions of different acidic and alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic‚ increases the growth of roots during the germination process of Cacurbita moschata‚ Beta vulgaris‚ and Capsicum annuum

The Effect of Microwave Radiation on the Respiration Rate of Phaseolus vulgaris Aerobic Celluar Respiration is a process that is carried out by most living organisms. The process is a series of chemical reactions that occur within the mitochondrial matrix and cristae of eukaryotic cells. Following the anaerobic process of glycolysis‚ partially broken down sugar molecules enter the matrix of the mitochondria where they are further reduced by oxygen. In the process‚ a small amount of ATP is created

THE EFFECT OF SALINE ON BEAN GERMINATION AUTHOR: Erik Motyka Lab-partner: MWCC Biology I-109 Professor: Dr. Atryzek ABSTRACT: The response of Phaseolus vulgaris to increased levels of saline solution at germination and seedling growth was investigated. Seeds were germinated in paper towels placed in plastic Ziploc bags with varying concentrations of saline solution and incubated at 25°C. At the end of 14 days the seeds

dermatology is primarily dedicated to the study and treatment of disorders of the skin‚ but sometimes will also treat cosmetic issues of the hair‚ scalp‚ and nails (Dermatology). A dermatologist may be known to treat disorders and diseases such as acne vulgaris‚ psoriasis‚ eczema‚ alopecia‚ rosacea‚ and impetigo‚ just to name a few (Pitman 120‚ 123-124). Dermatologists can be either surgical‚ medical‚ or both. Some therapies performed by dermatologists include: cryosurgery to remove warts‚ laser therapy
