Answer: Clostridium botulinium
Explanation:
An anaerobic bacteria is an organism which does not require oxygen for it's survival. It may not survive or die in the presence of oxygen. These bacteria are used for the process of fermentation for the preparation of beverage and dairy products.
Clostridium botulinium is the example of the anaerobic bacteria. It is found in soil or marine environment in the form of spores. This bacteria is rod shaped. It forms the spores when the conditions for survival is poor. It causes a disease called as botulism.
The mode of evolution that is represented by this example is
called coevolution. Coevolution is the process in which two independent species
influence the evolution of each other. This process involves natural selection.
There is nothing working as a forcing agent. Since this orchid named bumblebee
orchid is totally dependent on a single species named bumblebee for its
pollination and this evolution process, so this process is called coevolution. Various
other organisms also follow this method of pollination to continue their cycle
of evolution.
A phospholipid is composed of two fatty acids, a glycerol unit, a phosphate group and a polar molecule. The phosphate group and polar head region of the molecule is hydrophillic (attracted to water), while the fatty acid tail is hydrophobic (repelled by water). When placed in water, phospholipids will orient themselves into a bilayer in which the nonpolar tail region faces the inner area of the bilayer. The polar head region faces outward and interacts with the water.
Phospholipids are a major component of cell membranes, which enclose and protect the cytoplasm and other contents of a cell. Phospholipids are also a major component of myelin, a fatty substance that is important for insulating nerves and speeding up electrical impulses in the brain. It is the high composition of myelinated nerve fibers that causes white matter in the brain to appear white.
Steroids and Waxes

Steroids have a carbon backbone that consists of four fused ring-like structures. Steroids include cholesterol, sex hormones (progesterone, estrogen, and testosterone) produced by gonads and cortisone.
Waxes are composed of an ester of a long-chain alcohol and a fatty acid. Many plants have leaves and fruits with wax coatings to help prevent water loss. Some animals also have wax-coated fur or feathers to repel water. Unlike most waxes, ear wax is composed of phospholipids and esters of cholesterol.
