A Living Organism shows a high degree of organization. Millions of atoms and molecules are arranged in an orderly and complex way to composed of one cell produce a living organism or many cells. This needs a lot of energy. Also, a constant supply of energy is needed to maintain a living organism. Thus, obtaining and using energy.

• organ transplants,

• invitro fertilization (IVF) which helps infertile couples to have children.

• production of hybrid crop plants and
larm animals with desirable qualities.

• the use of biological pesticides instead of chemical ones in the control of agricultural pests

• the use ot naturally occurring bacteria toclean up oil spills and toxic chemicals (and possibly in the near future radioactive uranium wastes as well).

• production of single cell protein (SCP) by micro-organisms (this may save millions of people rom dying of protein deficiency).

• using genetically engineered microbes to manutacture, at low cost, substances which were difficult to produce such as insulin and interferon;

• using hybridoma technology to produce antibiotic

Currently, scientists are working on many important biological issues that affect our lives these range from ways of dealing with the world's exponential population growth and its demands to a cure for AlDS (Acquired Immune Deiciency Syndrome).

Exciting research is also going on in the field of genetic engineering which has opened up vast possibilities-such as being able to nd human beings of genetic diseases as well as brnnging out only their best qualities
