Food contains organic molecules such as ; energy is released when cells break down this molecule.

The correct answer will be-glucose molecules

Explanation:

The food contains all the molecules which provide the energy to the cell through the process of slow oxidation called cellular respiration.  The respiration provides energy to the cell by breaking down the food particles which provides the substrate like glucose and proteins.

The glucose is used as the major substrate as the cellular respiration breaks down the glucose molecule through glycolysis which is followed by the Citric acid cycle and electron transport chain.

Thus, glucose molecules are the correct answer.

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 !
