change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes we added a) 3.5 ml buffer b) 0.5 ml ONPG (substrate) c) 0.5 ml of the dilution that was incubated with the buffer (enzyme) Then we allowed the reactions to proceed for the 19 seconds‚ which we used in activity 2 for the pH7. Then we stopped it with 0.5 ml sodium carbonate. Then put it in the sec 20 to determine

All minerals have four properties: 1. All minerals are naturally occurring 2. All minerals are inorganic (that means non-living) 3. A different chemical formula can be written for each mineral and that formula is constant for that mineral. ex. Galena is PbS- that is it has one lead atom (Pb) and one sulfur (S) atom in each molecule. 4. Most minerals have an unique crystalline shape given the right growing conditions (like in a cave). Compounds are substances that has two or

Mineral and Water Function Minerals are a vital part of the body in many aspects. The functions of minerals vary by the mineral. Some minerals help in developing bone structures such as calcium‚ other assist in energy regulation‚ and some even assist with genetics. The amount of these minerals that the body needs also varies depending on the mineral. There are two types of minerals‚ major minerals and trace elements. We find the minerals that our bodies need from animals and plants‚ the amount of

Vitamin C also known as ascorbic acid is vital to our body. It can strengthen our body to resist against infection. It is known that deficiency of vitamin C can cause scurvy. Vitamin C is present in various fruits. Since vitamin C is a reducing agent‚ it can be deactivated by a wide range of oxidizing agents including atmospheric oxygen. Therefore‚ precautions are needed to prevent or minimize the degradation of vitamin C during sample preparation. The ascorbic acid exists in two forms which

Minerals Among Us Venture outside on any particular day‚ look down along the traversed path and select a rock‚ any rock‚ call it Exhibit A. Observe it for a moment. How fantastic would it be‚ to positively identify it? To know that by observing certain properties of this rock‚ it can be said with confidence‚ that this particular rock has calcite‚ halite‚ mica‚ quartz or any specific mineral. Well‚ “because the atomic structure of a mineral species is always the same‚ most of its physical properties

discovered in 1852 by a mineralogist by the name of John P. Calcite. Calcite is a carbonate mineral that is usually white or colorless‚ but can have variety of colors due to impurities. It is one of the world’s most important minerals and is the most common. Calcite is one of the softest minerals and can be found in sedimentary and metamorphic rocks. Calcite has more practical uses than most other minerals. This mineral can be found in limestone and marble which is makes up most of the Earth’s crust. The
