Which is a function of the spinal cord? a. it the spine to provide structural support for the body. b. it allows the back to be flexible and move at different angles. c. it transmits information between different parts of the nervous system. d. it produces hormones to send chemical signals throughout the body.

The correct answer is option C which is the function of spinal cord is to transport information between different parts of the nervous system.

Nervous system has two parts:

Central nervous system includes brain and peripheral nervous system includes spinal cord.

Spinal cord receives nerve impulses from body and transport it to the brain.

It also receives orders in form of nerve impulses which are transported to receptors for response.

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 !

a physical change is being made.
