Q:How to isolate the effects of inorganic salts on enzyme solubility: The effect of inorganic salts on the solubility of the enzyme was studied. The inorganic raw materials were pretreated with inorganic salts to separate the solid-liquid phase, and some of the lignin and hemicellulose were dissolved, and the sulfuric acid and the inorganic salt were added to the cotton Treatment, thereby improving the enzymatic hydrolysis efficiency. Using different amounts of sulfuric acid

Q:The lack of three major inorganic salts can cause symptoms in the plant: Potassium: Stable stem to promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry. In addition to these three types of inorganic salts, plants also require many types of inorganic salts.

Q:What is the difference between inorganic and inorganic salts?: Organic matter is defined as: all substances that are carbon-containing substances, organic substances other than carbon dioxide, carbonates, carbon monoxide, cyano substances, elemental carbon itself, etc. are generally used in the field of organic chemistry, including natural generation Of organic matter and synthetic organic matter (especially polymer-based organic matter)

Q:give me at least 5 substances: Inorganic Bases

Q:What is the inorganic salt in the egg: Eggs are rich in nutrients. It contains protein, fat, vitamins and inorganic salts, enzymes and so on. These nutrients on the body's growth and development, health and longevity have a great effect.

Q:The effect of inorganic salt medium and the difference with enrichment medium: The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.

Q:What is the composition of inorganic salts?: Inorganic salts are inorganic compounds in the salt, formerly known as minerals

Q:I need help with this: anything which contain carbon is organic. so enzyme is the odd one out.

Q:What are the disadvantages of inorganic salt deficiency and too much: The role of inorganic salts in plant life Plants require the most inorganic salts to be nitrogen-containing, phosphorus-containing and potassium-containing inorganic salts. These three types of inorganic salts have different effects in plant life. Lack of performance nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown. P: Promote the development of seedlings and the opening of flowers so that the fruit and seed are mature early. Lack of performance: the plant is particularly short, leaves were green, and purple. Potassium: Stable stem to promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry. In addition to these three types of inorganic salts, plants also require many types of inorganic salts. Among them, the demand for some inorganic salts is very small, but they are in the life of the plant also plays a very important role. For example, the lack of iron-containing inorganic salts, fruit trees will be yellow leaf disease; lack of boron-containing inorganic salts, rape will be "spent" (only flowering fruit)

Q:is sugar and salt organic or inorganic?: sugar is organic salt is not. Sugar is made from carbon that's why it's organic in compound
