Biology An Overview
Is it possible to take DNA from living things that is already living on Earth and mix it creating new species and bacteria? Can we change DNA so that a type of organism can be different from others (can breathe in water, can survive in the cold, can withstand strong winds, can eat certain stuff, can be very powerful or fast.)
Genetic modification is already quite prolific - many of your fruits and vegetables have DNA from other species spliced into it. For example, there are tomatoes which have been genetically modified with genes from fish (specifically the winter flounder) to provide them greater resistance against frost. Genes from bacteria have been added to provide everything from pest resistance to greater nutritional value.

The nervous system includes both the Central nervous system and Peripheral nervous system. The central nervous system is made up of the brain and spinal cord, and the peripheral nervous system is made up of the Somatic and the Autonomic nervous systems.
The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. Wikipedia
The GI (gastrointestinal tract) is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.
The skeletal system is your body's central framework. It consists of bones and connective tissue, including cartilage, tendons, and ligaments. It's also called the musculoskeletal system.
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.
