The correct answer is option A, that is, a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom.
Carbohydrates are the main source of diet, they provide energy to the body, mainly via glucose, a basic sugar, which is a part of the starch and an ingredient in various staple foods.
The carbohydrates can be signified by the stoichiometric formula, that is, (CH2O)n. It can be also be stated that the ratio of the carbon to hydrogen to oxygen is 1: 2: 1 in the molecules of carbohydrates. Carbohydrates are further categorized into three sub-kinds, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the simple sugars, for example, glucose.
Hi,
By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.
Option c) is the correct option above.
<span>c) Fossils give information about the time period in which organisms lived in the past.

Well, ask yourself, "Do I try hard enough?" "Was it the best I could do?" And well if the answer is yes, then you have nothing to stress out about too much. Maybe talk to your teacher and ask for extra credit. Get tutoring. Talk to a guidance counselor. If none of that helps, well then you're just not the best at the subject, but just try your best. In the future, you won't even remember about all those grades! Coming from a 6th grader, the beginning of the year was super hard. I'm not the best at math, but I'm very good at Language Arts. Everyone has their own weaknesses and strengths. Don't worry about it.
