Aquatic ecosystems that are composed of salt water are coral reefs, open ocean, and intertidal zones. Neritic zones also have salt water, but the salinity levels are very light. :)
The amount of dissolved salt present in the water is calculated in the terms of the practical salinity unit or PSU or ppt.
The salinity of the inter-tidal zone lies between 20-25 ppt whereas the salinity of the ocean lies between the 33-35 ppt. The salinity of the coral reefs lies between the 30-40 ppt.
The stream is the freshwater source which contains very less amount of salt and the neritic zone is the zone of the ocean in which sunlight can easily reach which contains low salt concentration.
Thus, the selected options are the correct answer.
Answer: Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
The enzyme influences the speed of change from substrate to product. Enzymes are released as substrates in a chemical reaction. An enzyme is a special kind of substrate in a chemical reaction.
