the enzyme pepsin breaks down proteins from food into peptides and originates from cells lining the stomach. what mechanism prevents pepsin from digesting the stomach's own cells?
Pepsin is a proteolytic enzyme that is synthesized & secreted by the chief cells in the stomach lining (specifically, the fundus & body of the stomach). Pepsin functions by breaking down proteins in food into smaller peptides that can be further digested & absorbed in the small intestine.
Pepsin can digest proteins, which begs the issue of how it is kept from also eating the stomach's own cells. The elaborate design of the stomach's lining and the defence systems hold the key to the solution to this query.
The presence of a thick coating of mucus that covers the mucosa's surface is one of the main defences against pepsin's digestion of the stomach lining.
Pepsin is physically prevented from getting into touch with the stomach's epithelial cells by this layer of mucus. The mucus layer serves as a physical barrier, but it also contains bicarbonate ions that aid in neutralising any acids that may come into touch with the epithelial cells.

the tympanic membrane connects to three tiny bones that, in turn, transmit the vibrations to the ____.
The tympanic membrane connects to three tiny bones (the malleus, incus, and stapes) that, in turn, transmit the vibrations to the cochlea.
The cochlea is a spiral-shaped organ located in the inner ear of humans and other vertebrates that plays a crucial role in hearing. It is filled with fluid and contains thousands of tiny hair cells that are responsible for converting sound waves into electrical signals that the brain can interpret as sound.
When sound waves enter the ear canal, they cause the eardrum to vibrate. These vibrations are transmitted through the bones of the middle ear to the cochlea, where they cause the fluid inside to move. This movement stimulates the hair cells, which then generate electrical signals that are sent to the brain via the auditory nerve.
The cochlea is divided into three sections: the scala vestibuli, the scala media, and the scala tympani. The scala media is where the hair cells are located, and it is separated from the scala vestibuli and the scala tympani by a thin membrane called the basilar membrane.

how can secondary succession contribute to the carbon cycle?
Secondary succession is a natural process of ecological recovery that occurs after a disturbance, such as a fire or a clear-cutting. During secondary succession, new plants and animals colonize the area, and the soil gradually becomes richer in nutrients. As the plants grow, they absorb carbon dioxide (CO2) from the atmosphere during photosynthesis and store the carbon in their tissues.
As the plants die and decompose, the carbon in their tissues is released back into the atmosphere as carbon dioxide or is stored in the soil. This process contributes to the carbon cycle by cycling carbon through the biotic and abiotic components of the ecosystem.
In addition, secondary succession can also lead to the establishment of new forests, which are important carbon sinks. Forests absorb and store large amounts of carbon dioxide from the atmosphere, helping to mitigate the impacts of climate change.
Overall, secondary succession plays an important role in the carbon cycle by facilitating the growth and storage of plants, which helps to regulate the levels of carbon dioxide in the atmosphere.

how do heart valves ensure one-way blood flow through the heart? why do you think one-way flow is important? how do the heart sounds audible with a stethoscope relate to heart valve action?
Blood flow through the heart is kept to one direction thanks to heart valves. The tricuspid, mitral, pulmonic, and aortic valves are the four valves in the heart.
These valves prevent blood from flowing backward by opening and closing in response to variations in pressure inside the heart chambers. Blood must constantly one-way flow in the proper direction in order for circulation to be effective, hence one-way flow is necessary to achieve this.
When the heart valves are closing when the sounds-audible are created, they are related to heart valve activity and may be heard using a stethoscope. On the beginning of systole, the mitral and tricuspid valves close, resulting in the first heart sound (S1), and the second heart sound (S2) is produced by the contraction of the pulmonary (S2).
