Answer;

-Crust and the upper most mantle

Explanation;

-The inside of the Earth is made up of three main layers, which are the crust, mantle and core. Compared to the mantle, the crust is very thin and brittle. The mantle is located below the crust and above the core of the Earth. The mantle layer of rock is approximately 2,900 kilometers thick.

-A tectonic plate (also called a lithospheric plate) is a massive, irregularly shaped slab of solid rock which move as cohesive, rigid bodies on the earth's surface. Tectonic plates have a large range of sizes and thicknesses.

-Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.

digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most like
horrorfan [7]

The most likely explanation to the statement that digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach is C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

The pH of the mouth is near neutral whereas the pH of the stomach is acidic due to the hydrochloric acid present in the stomach.

All enzymes, including the digestive enzymes, require a certain pH at which they are better able to function. If the pH is altered, then the shape of the enzyme changes, which affects the shape of the active site of the enzyme. As a result, the substrate is no longer able to fit in the active site.

Hence, those digestive enzymes that function in the mouth will not function in the stomach due to the altered pH.

Although a part of your question is missing, you might be referring to this question:

Digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most likely explanation?

A. Enzymes have only one active site. Once a substrate binds, that enzyme is no longer usable.

B. Enzymes are changed in a reaction. Enzymes made in the mouth are used up by the time they get to the stomach.

C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

D. There are no substrate molecules left when the enzyme reaches the stomach, so the enzyme stops working.

The nervous system is a complex system that is made up of nerves and nerve centers in different organisms that carries messages to and from the brain and the spinal cord to send them into various parts of the body.

It is primarily divided into-

1) CNS that is central nervous system ( made up of brain and spinal cord). The CNS is responsible for the voluntary functions of the body.

2) PNS that is peripheral nervous system ( possess cranial and spinal nerves arising from brain and spinal cord respectively). It controls the involuntary functions of the body.
