A virus infects a lung cell and begins replication. The lung cell releases interferon into the extracellular environment where it can be picked up by other nearby cells. As a result, the other nearby cells slow down their protein-making machinery to slow down viral replication should they become infected. This is an example of what kind of communication
Answers
Answer: The options are not given but it is gotten from another websites and here are the options.
A.Cell-to-cell (membrane molecule) recognition
B. Cell junctions
C. Paracrine signaling
d. Synaptic signaling
The correct option is C.
Paracrine signaling.
Explanation:
This is because in paracrine signaling cell communicate with other near by cells through chemical Messengers. It is a form of cell to cell communication in which a cell produced signal and transfer it to other neighbouring cells whereby the neighbouring cells alter or change their behavior to counter the effect of the signal. From the question, the lung cells send signals to neighbouring cells and this alter their behavior by slowering down protein making machinery.

breathing in physical phenomenon. what movement does happen when a person breathe in?
Answers
When a person breathes in, the diaphragm contracts and the lungs expand, creating a vacuum that draws air into the lungs. The air is then circulated through the lungs, where oxygen is absorbed and carbon dioxide is released.
What should know about the body parts that functions when you breath-in?The diaphragm is a vital muscle in inhaling (breath-in) and exhaling, separates the chest cavity from the abdominal cavity.
When the diaphragm contracts, it flattens and moves down. This increases the space in the chest cavity, which causes the lungs to expand. The lungs are elastic, so they expand when the space around them increases.

Answer:
The term "weather" means the state of the atmosphere in a shorter period of time, while the term "climate" refers to how the atmosphere behaves in the long run.
Explanation:
When we talk about climate change, we are talking about long-term change.
"tTme" describes the way in which the atmosphere "behaves", which primarily means the effects that this "behavior" has on life. The biggest difference between climate and weather is that the term "weather" refers to extremely short-term changes in the atmosphere - so short that they are measured in minutes and months.

c. Postnatal development of the immune system in mice is affected by exposure to bacteria during a critical period immediately following birth.
d. Early exposure to one allergen does not affect later responses to other allergens, thereby demonstrating that immune responses are very specific.
e. Results from these studies support the hygiene hypothesis as it is used to explain the rising incidence of allergies and chronic inflammatory diseases in some human populations.
Answers
The conclusion that can be drawn from studies in rats about how endotoxin exposure after birth susceptibility to dust mite allergy in later life is early exposure to one allergen does not affect subsequent responses to other allergens, indicating that the immune response is highly specific.
The true choice is D.
Mites can cause allergies to the skin by using female mites entering and then burrowing under the skin and creating channels to lay eggs. After the eggs hatch, the mite larvae then move to the surface of the skin to grow. The mites, their eggs, and excrement make the skin itch as an allergic reaction of the body to the presence of mites.
The immune response is very specific, namely the immune system that your body forms after being exposed to certain foreign substances. So from this study, there was no significant relationship between the density of house dust mites and the degree of allergic rhinitis.

Explanation:
Hope this helps!!
Air masses can cause short-term heat waves, in which temperatures are higher than normal. Short-term periods of low precipitation can cause some areas, such as India, experience periods of heavy precipitation every year known as monsoon.
What are heat waves?Substantively, a heat wave is an ailment of high air temperature that is lethal to the human body when revealed.
It is defined quantifiable based on temperature thresholds more than a region in terms of the real temperature or deviation from normal.
The wavelength of infrared waves is long enough to cause molecules and atoms to vibrate.
As a result, whenever an object comes into contact with infrared waves, it generates heat due to atom vibrations. This is why infrared waves are referred to as heat waves.
A monsoon is a large-scale weather system characterized by a seasonal shift in wind direction over a specific region, which is usually coupled with a rise in atmospheric moisture and precipitation.
Thus, short-term heat waves can be caused by air masses, which cause temperatures to rise above normal. Short-term low precipitation can cause some areas, such as India, to experience annual periods of heavy precipitation known as monsoon.

Why does nitrogen fixation play a role In the nitrogen cycle
Answers
Nitrogen fixation is the process in which procaryotes take the atmospheric nitrogen (N₂) and use it to produce ammonia (NH₃). Ammonia can be used by plants as a nutrient that helps them grow properly.
The role the process plays is very important because it transforms the nitrogen of the air into usable nitrogen for the plants.
Nitrogen is a very important nutrient in nature and agriculture when in the absence or low in supply, the plants can't grow healthy.
If 13.6 L of nitrogen at 514 mm Hg are compressed to 500 mm Hg at constant temperature. What is the new volume?
Answers
Considering the Boyle's law, the new volume is 13.9808 L.
Boyle's lawBoyle's law establishes the relationship between the pressure and the volume of a gas when the temperature is constant, determining that the volume occupied by a given mass of gas at constant temperature is inversely proportional to the pressure.
This means that if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.
Boyle's law is expressed mathematically as:
P×V=k
Now it is possible to assume that you have a certain volume of gas V1 which is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and the following is true:
P1×V1=P2×V2
New volumeIn this case, you know:
P1= 514 mmHgV1= 13.6 LP2= 500 mmHgV2= ?Replacing in Boyle's law:
514 mmHg ×13.6 L= 500 mmHg ×V2
Solving:
(514 mmHg ×13.6 L)÷ 500 mmHg= V2
13.9808 L= V2
Finally, the new volume is 13.9808 L.

what is the resting phase of the cell cycle called?
A. Prometaphase
B. Mitosis
C. Interphase
Answers
The resting phase of the cell cycle is called interphase.
Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.
This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.
Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.
