N.S Exam Study Notes • Matter&Material • Matter-everything around you‚ it is anything made of atoms and molecules. It’s anything that has a mass. Matter is related to light and electromagnetic radiation. Usually found in a few forms and it has 5 states- (Solids‚Liquids‚Gases‚Plasmas‚Bose Einstein Condensates) • Mass- It is the amount of material in an object. It is the same on Earth or Mars. It is the amount of matter which an object contains. • Weight- It is how heavy something is. It is a

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

Kale-Apple Smoothie: Dark green veggies‚ which are a food group that includes leafy greens such as kale‚ spinach and dandelion greens‚ should make regular appearances in your diet. Kales are rich in phyto nutrients which could help protect against sun damage. Spinach is loaded beta-carotene and lutein which help improve skin elasticity. Strawberries: Berries not only rich in fiber but also packed with age-defying antioxidants‚ which

Commonly known as “Alugbati” here in the Philippines is a leafy-soft-stemmed vine vegetable that contains a lot of vitamins and minerals that somehow discovered and called‚ “a vegetable with a use”. In some foreign countries‚ it is called Malabar spinach‚ that contains vitamin A‚ vitamin C‚ iron‚ and calcium that can help a human body more productive and even healthier. I come up with an idea‚ that why don’t we try to innovate an ink that is economically available and that can be seen in our own

The effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights‚ one green and one a normal light‚ that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows

The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll The energy of the light is absorbed by chlorophyll and in turn supplies the plant with energy to transform carbon dioxide and water into oxygen and carbohydrates.

Chlorophyll is a green pigment found in almost all plants‚ algae‚ and cyanobacteria that are critical for in

water samples that were collected from the Pacific coast of Japan (unpublished results). Among the isolates‚ a novel‚ highly selective astaxanthin-producing marine bacterium‚ labeled strain (N-5)‚ was isolated based on its ability to produce orange pigment on NA plate after 2 days of cultivation at 30 °C. Strain N-5 formed colonies that were medium in size (1.0−2.0 mm in diameter)‚ circular‚ shiny‚ and orange (Figure 1B). Unless otherwise specified‚ all characteristics described hereafter are those
