Answer:
All carbohydrates have the general formula Cn(H2O)n
Explanation:
The basic unit of carbohydrates-monosaccharides have the formula C
nH
2nO
n while the basic general formula of carbohydrates is Cm(H2O)n .
Monosaccharides are basic units (components) of carbohydrates. Those are simple sugars such as glucose, fructose, galactose. Two monosaccharides can join together via glycosylic bond and make disaccharides. Some of the disaccharides are: sucrose (glucose + fructose), lactose (galactose + glucose), maltose (glucose + glucose).
Disaccharides can be broken down to monosaccharides by an enzyme called a disaccharidase.
Longer chains of monosaccharides form oligosaccharides (usually as glycolipids ) and polysaccharides (starch, glycogen,cellulose, chitin).
Carbohyrates are important biomolecules included in metabolism, energy storage, they are also structural components, have role in immune response, as coenzymes etc.
Answer:2
Explanation:cytokinesis is the division of cytoplasm which occurs after cell division
Fossil records provide evidence of natural selection because one can see what species and what type of species (specifically what type of special trait the species had) reproduced and lived for longer.
For example, we have 5 different fossils of the same animal;
1. Lived about 45 years; had long legs that made it run faster - 5 offspring
2. Lived about 8 years; had short and stubby legs, was very slow - 0 offspring
3. Lived about 67 years; had long legs that made it run faster and a good nose - 8 offspring
4. Lived about 40 years; had a good nose and normal legs - 6 offspring
From all of that information you can see that the prefered trait was having longer legs and a good nose survived and reproduced multiple time, you can also see that the organism that had short legs did not survive for long and did not reproduce.
