Question

A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the independent variable is The water The amount of salt in the water The temperature of water The number of plants in the water Saturated fatty acids differ from unsaturated acids in the regards Single hydrogen bonds vs double hydrogen bonds respectively double vs single hydrogen bonds respectively double hydrogen bonds vs triple hydrogen bonds respectively triple vs double hydrogen bonds respectively What are the products of photosynthesis? water and carbon dioxide glucose and water water and oxygen glucose and oxygen

Explanation / Answer

64) A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the independent variable is the amount of salt in the water. Salt water is water that contains a significant concentration of dissolved salts(mainly NaCl). The salt concentration is usually expressed in parts per thousand and the use of salt water increased at a much higher rate than freshwater use.

65) Saturated fatty acids differ from unsaturated fatty acids in regards the single hydrogen bond vs double hydrogen bonds respectivily.Hydrogenation adds hydrogens to unsaturated fats to reduce the number of double bonds and make fats more saturated and resistant to oxidation.Saturated fatty acids have no double bonds, but unsaturated fatty acids have one or more than one double bonds.

66) The products of photosynthesis are Glucose and Oxygen.Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy. This chemical energy is stored as sugars or glucose, which are synthesized from carbon dioxide and water. Oxygen is also released asproduct.

water+ carbondioxide= Glucose+ oxygen
