The digestive and excretory systems project explaining macromolecules in the body

Our digestive system has the ability to convert macromolecules into micromolecules.

Explanation:

Our digestive system has the ability to convert macromolecules into micromolecules with the help of certain enzymes. Carbohydrate is a macromolecule which is converted into glucose molecule with the help of saliva which is an enzyme present in the mouth, protein is also a macromolecule that is converted into amino acid so that our body cells can absorb it and fats are also macromolecules which can be converted into fatty acids with the help of digestive system. The cells produced waste materials such as carbondioxide gas and nitrogenous material which can be excreted through excretory system such as lungs and urinary bladder.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
