Answer:
(b). All carbohydrates have the general formula 
Explanation:
Carbohydrates, more commonly known as sugars, are made up of carbon, oxygen, and hydrogen atoms. As mono-saccharide is known as the smallest unit of a carbohydrate . Two monosaccharides make up a disaccharide, and many monosaccharides make up a polysaccharide. Disaccharides and polysaccharides can be hydrolyzed back into the individual monosaccharide units.
As we know that the carbohydrate is always represented as
,
where n is any number between three and eight.
Hence, the option (b) is incorrect.
Plasma has a neutral charge, as well as the same amount of protons and electrons put together. if the question has only one answer then it is plasma.
Salt makes the freezing point of water decrease, so it would freeze at a warmer temperature than regular water
<span>The independent variable is the one that researchers directly change. Here, the students will deliberately change the temperature, so the independent variable will be temperature in degrees. The dependent variable is the one that researchers measure as the outcome of the experiment. Here, the students will measure the time it takes until the water is gone (evaporated), so the dependent variable will be time, in units of seconds or minutes or hours.</span>
