Piaget developed four universal stages of development. The first stage‚ the sensorimotor stage‚ occurs around 0-2 years. The second stage is the pre-operational stage‚ and lasts from approximately 2-7 years. The next stage is the concrete operations stage‚ which lasts from around 7-11 years. The final stage‚ formal operational thought‚ occurs around age 12 and lasts into adulthood (Mooney‚ 2013). In researching Piaget’s stage theory‚ and the corresponding characteristics‚ kindergarten children

Anti-cancer Drug Screening in Vitro Introduction: The incidences of cancer remain high despite advances in our understanding of cancer. Cancer is a class of diseases characterized by out of control cell growth. Normal cells are constantly subject to signals that control whether the cell should divide‚ differentiate into another cell or die. Cancer cells develop a degree of independence from these signals‚ which results in uncontrolled growth and proliferation. If this proliferation is allowed

Specific Objective: Carry out test for reducing sugar‚ non reducing sugar‚ starch ‚ protein and lipid. BIOCHEMICAL TESTS Reducing and non-Reducing Sugars Sugars can be classified as either reducing or non-reducing based on their ability to reduce copper(II) ions to copper (I) ions during the Benedict’s Test. Reducing sugar have contain free aldehyde or ketone group and have the ability to reduce copper(II) ions to copper (I) ions during the Benedict’s Test. All monosaccharides are reducing

Results In this experiment we used paper chromatography to determine the amount of chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta-carotene in a tube of blended leaf extract. We recorded our findings on the table labeled table 1. Table 1 shows the transmittance at each wavelength on a table from 400 to 720. The information on Figure 1 came from the leaf extract on the paper chromatography that we used; with the help of acetone we saw the spectrum and the differences of the different pigments
