The mouth generally has a neutral pH close to 7. When salivary enzymes are swallowed and enter into the stomach, the enzymes will be activated by coenzymes in the stomach. Thus, option D is correct.
What happens when pH is too low in the stomach?
If the pH is too low in the stomach, it will denature the proteins that usually break down food. The major enzyme in the stomach is pepsin, which breaks down proteins in the food we eat. Therefore, the answer is the second statement, "Decrease in pH of the stomach will distort the active site of the enzyme pepsin, which affects its action.

a cell's membrane potential is maintained by the movement of ions into and out of the cell. A model showing the influence of membrane proteins on the movement of sodium and potassium ions across the plasma membrane is represented in Figure 1. Based on the model represented in Figure 1 which of the following outcomes will most likely result in a loss of protein x function?
Answer:
Increase in k+
Explanation:
It won’t leak out
The loss of protein x function would lead to an increase in intracellular potassium ion ( K+) concentration.
Protein X is a membrane protein which is a molecule that is attached to the cell membrane of a cell that helps in the control of ions into and out of the cell.
Depending on how these proteins are associated with the cell membrane, there are different types which include:
Integral membrane proteinsPeripheral membrane proteinsProtein X is an example of integral membrane protein because it's located inside the cell membrane.
From the diagram above, Protein X helps in the transport of potassium ion ( K+) out of the cell.
Therefore once there is loss in function of Protein X, potassium ion ( K+) will increase intracellularly.

All organic molecules contain carbon atoms that ultimately can be traced back in the food chain to carbon dioxide from the atmosphere.
What is food chain?A food chain is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.
Moreover, a food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
Hence, animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.

Explanation:
i took the test
The correct option is (B). Molecules of a compound.
What do you mean by molecules?A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Moreover, molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
Hence, the smallest particle of any substance which can exist independently and retain the physical and chemical properties of the substance, made up of one or different elements is a molecule.

Even though the Pacific and Antarctic Plates are among the largest, their widths can vary from a few hundred to thousands of kilometers.
What is the tectonic plates using the drop-down menus?Two tectonic plates colliding results in the formation of a convergent plate boundary. One of the convergent plates sliding down under the other is called subduction.
Where tectonic plates are subducting, deep trenches frequently occur, and subduction zones frequently experience earthquakes as well.
The earth's surface is made up of enormous rock slabs called tectonic plates. These plates shift positions periodically and travel slowly.
A significant slab of solid rock with an irregular shape is referred to as a tectonic plate, also known as a lithospheric plate, and it is often composed of both continental and oceanic lithosphere.
Therefore, A—pacific plate B—North American plate C—Eurasian plate D—Indian plate.
