Explain what a carbohydrate is and give at least one example.

1- Monosaccharides: Simple sugars, the simplest carbohydrate form. In general, the basic molecular formula is (CH2O)n. Monosaccharide' function: a source of energy for organisms. Examples: Glucose, galactose, and fructose.

2- Disaccharides: consist of two monosaccharides joined together by a covalent bond. This bond is generally between the number 1 carbon of one monosaccharide and the number 4 carbon of the other molecule. Disaccharides' function: a nutritional source of monosaccharides. Examples: sucrose or table sugar, maltose, and lactose.

3- Polysaccharides: composed of thousands of monosaccharides. The addition of new monosaccharides could continue indefinitely making a huge molecule forming a long (and branched via the 6- carbon) chain of glucose molecules. This long chain is known as a polysaccharide. Polysaccharides' function: an easily accessible storage form of glucose. Examples: starch and glycogen.

Animals will lose energy because it is converted to heat

The fetus at this stage is curled up, almost doubled over, so remember to consider this as you draw the fetus the correct length
