Explain how a streamlined, smooth, nearly hairless body is a beneficial adaptation for marine animals.
lana66690 [7]

Most of the marine animals have a stream lined body, which means, they have a sharp and pointed at the front. The pointed front of the organism allow to cut the resistance of the water. In case, the body is not pointed at the front and it is blunt, the water current and flow would resist the movement of the organism further. So, for the locomotion purpose, it is important to have a streamlined body. Further smooth and hair less body also decrease the resistance during the movement in the water.

Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.

Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.
