Answer:
Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.
Explanation:
Answer:
The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

The production of orchids by cutting is an example of.
The production of orchids by cutting is an example of vegetative propagation.
There are two methods of growing orchid trees i.e. through seed as well as from vegetative part. Most of the farmers grow orchids plants through vegetative propagation because it takes less time to reach maturity while on the other hand, growing orchids through seed takes more time.
So that's why the farmer prefers vegetative propagation as compared to seed so we can conclude that the production of orchids by cutting is an example of vegetative propagation.

Answer:
Desert
Explanation:
Deserts are very dry and rocky which is what Chaz is explaining
A type of biome that is very dry, with soil made mostly of sand and rock found in California is known as the desert.
What are biomes?Biomes has been considered as the higher level of organization than ecosystems. Biomes are land areas formed by the influence of climate, rainfall, and latitude. There are various kinds of biomes namely desert biome, prairie biome, savanna biome, tropical forest biome, deciduous forest biome, tundra biome, and mangrove forest biome.
The Mojave Desert is a desert that comprises parts of southern California and small parts of Northern California, southwestern Utah, southern Nevada, and northwestern Arizona, in the United States.
A desert is a biome which receives very little annual precipitation. As a result of this it exhibit very hot and dry climatic conditions. The soil generally losses it's fertility which may either become compact or remain in loose form due to erosion like sand. The plants exhibit fleshy leaves so as to prevent the loss of water through transpiration.
Therefore, A type of biome that is very dry, with soil made mostly of sand and rock found in California is known as the desert.

Choose all that apply. Which of the following is true in a comparison of your skin cells to your kidney cells?
1) conduct translation differently
2) contain different DNA
3) contain different chromosome
4) transcribe many different genes
5) conduct replication differently
6) have different transcription factors
7) contain different genes
Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".
The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.
What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

Answer:

Explanation:
the type of voltage-gated channel that possesses an inactivation gate that temporarily closes after the channel is active is the
The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.
In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).
Characteristically, this channel has two transmembrane voltage-dependent gates.When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.

Answer: If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will D. complete the cycle and divide. G1 checkpoint occurs between the G1 and S phase of the cell cycle. When the cell is grown sufficiently and produces all components of DNA replication it enters in the S phase.
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide.
What is cell cycle?The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.

What are some geological characteristics of glaciers in Glacier National Park?
Answer:
The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.
