The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The carbon cycle was initially discovered byJoseph Priestley and Antoine Lavoisier.
Carbon returns to the atmosphere and water by
Carbon moves from the atmosphere to plants.
Carbon moves from plants to animals.
Carbon moves from plants and animals to the ground.
Carbon moves from living things to the atmosphere.
Carbon moves from fossil fuels to the atmosphere when fuels are burned.
Carbon moves from the atmosphere to the oceans.

The tiger is native to Asia. Tiger is solitary and territorial animal, that it lives in forest and also in savanna. The tiger is the largest feline in the world. Male tigers have a weight between 100 and 306 kg and 220-330cm in longitude including the tail. The females, much smaller, have a weight of 85 – 167 kg. and a total logitude of 210-275 cm.
Most tigers have an orange coat and stripes varies from dark brownto black. The shape and number of stripes vary according to theirsex (if it is female the number of stripes is lower).
Nowadays, the biggest enemy of the tiger is the human, to take it fur and bones. Tiger bones have been used in traditional Oriental medicine,although today this practice has been prohibited in China. The illegal hunting to obtain the skin, and habitat destruction have reduced the wild tiger population.

An example of mutualism is the buterfly and a flower. The buterfly get food from the flower and the flower benefits from the buterfly because it help to reproduce.

Lyell wrote the Principles of Geology. Principles of Geology being an attempt to explain the former changes of the Earth’s surface. Published in three volumes in 1830–33. It established Lyell’s credentials as an important geological theorist and popularised the doctrine of uniformitarianism. The central argument in Principleswas that “the present is the key to the past”: that geological remains from the distant past can, and should, be explained by reference to geological processes now in operation.
Lyell’s interpretation of geologic change as the steady accumulation of minute changes over enormously long spans of time was also a central theme in the Principles, and a powerful influence on the young Charles Darwin, who was given Volume 1. Darwin found rock formations which gave him a revolutionary insight into the geological history of the island. Darwin received Volume 2, which rejected the idea of organic evolution, proposing “Centres of Creation” to explain diversity and territory of species.

The tools you’ll need to clone are:
- 3 diferent mammal of the same specie
- Petro dishes
- Sharp pipette
- Blunt pipette
- Chemical to stimulate cell division
- Remove a somatic cell of the mammal that you’ll be cloning and a egg cell from other mammal.
- Discard the nucleus from the egg cell.
- Transfer the somatic nucelus into the enucleated egg cell.
- Stimulate cell division
- Finaly, implant the embryo into the mother
Fold is when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of plastic deformation.
Two types of folds:
–Anticline: is a fold that is convex
–Syncline: is a fold that is concave
And in this picture we can see the differents parts of a fold
