Answer:
the first organism on the food chain
Explanation:
Answer:
In anaerobic respiration, one molecule of glucose is broken down into two molecules of ethanol (in yeast) or lactic acid (in muscle cells) with a net gain of two molecules of ATP (adenosine triphosphate).
Two molecules of carbon dioxide are released as the byproduct.
It helps in regenerating the NAD⁺ lost in the process of glycolysis.
The overall process is termed as fermentation.
Lactic acid fermentation is catalyzed by the enzyme lactate dehydrogenase and alcohol (ethanol) fermentation is a two-step process which is catalyzed by pyruvate decarboxylase and alcohol dehydrogenase.
Answer: True
Ocean water is saline. The salt in the ocean comes from rocks on land. The rain falls on the rocks erodes the rocks . The rain being acidic in nature due to the presence of carbonic acid creates ions, or electronically charged atomic particles. These ions are carried away by the streams of rivers and ultimately to oceans. The two of the most abundant ions produced by this process are sodium and chloride. These make up 90% of dissolved ions in the ocean. The concentration of the salt in seawater is about 35 parts per thousand. In other words about 3.5 percent of the weight of seawater comes from the dissolved salts.
