Animals digestive systems have evolved a lot over a long period of time to adapt to be able to digest the required diet for survival
Humans have adapted by making medicine to fight off deadly viruses and we use many plants to help fight off these illnesses.
Plants are genetically modified to taste and look better for consumers
Viruses copy it's DNA in a host cell to reproduce
Plants use photosynthesis to create oxygen and energy in the form of sugar
Different animals have different circulatory systems, open and closed circulation is very different. In open circulation there are no veins and blood comes in direct contact with the organs where closed circulation has veins to conduct the blood.
Algae are autotrophs and they produce their own "food". They do not have a digestive system.
Oxygen produced by the plants is inhaled by humans, and the carbon dioxide exhaled is consumed by the plants
Different animals have different respiratory systems. Fish and mammals breathe differently. Fish breathe through their gills, us humans use our lungs
Humans select desired traits and only breed for those traits so that those traits will be bred consistently within a species. this will lead to different diversity within the species that is domesticated and wild.
Offspring recieve the genes from their parents who survived to mate. These characteristics were passed on because natural selection allowed for them to continue to exist.
Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.

With prenatal testing it is now possible to see how your baby is coming along, weather it is healthy or not and how it may come out. For example you can test for genetic disorders such as down syndrome.

Natural selection is the idea of survival of the fittest. The animals that can get food to nourish themselves to survive and reproduce will pass their genes onto the next generation.

Plants and animals make adaptations to be able to survive in their given habitat.
