Answer:
In a hypotonic solution, an animal cell will fill with too much water and lyse, or burst open. However, plant cells need more water than animal cells, and will not burst in a hypotonic solution due to their thick cell walls; hypotonic solutions are ideal for plant cells.
Explanation:
Please mark me Brainliest!
The presence of a rigid cell wall in plant cells allows them to withstand the pressure changes that occur in a hypotonic solution, whereas animal cells without a cell wall are vulnerable to lysis. This difference highlights the importance of understanding the unique features and responses of different cell types to changes in their environment.
Animal cells and plant cells are two types of eukaryotic cells with different structures and functions. One major difference between these two cell types is the presence of a rigid cell wall in plant cells but not in animal cells. In a hypotonic solution, which has a lower concentration of solutes compared to the concentration inside the cell, both plant and animal cells will experience changes in their volume and shape. However, the responses of these two types of cells to a hypotonic solution differ due to their structural differences.
When placed in a hypotonic solution, animal cells and plant cells will both experience a net movement of water into the cell. This is because water will move from an area of high concentration (outside the cell) to an area of low concentration (inside the cell) in an attempt to balance the concentration on both sides of the cell membrane.
In animal cells, the influx of water will cause the cell to swell and potentially burst (lysis) due to the lack of a rigid cell wall to maintain its shape. As water enters the cell, the volume of the cytoplasm increases, and the cell membrane stretches until it can no longer contain the excess water. This bursting of the cell can cause damage to surrounding tissues and can ultimately lead to cell death.
In contrast, plant cells have a cell wall that provides structural support and prevents them from bursting in a hypotonic solution. The influx of water will cause the plant cell to swell, but the cell wall will prevent it from bursting. Instead, the increased pressure on the cell wall causes the plant cell to become turgid, which is important for maintaining the structural integrity of the plant. The turgor pressure also helps to maintain the shape of the plant and allows it to stand upright.
However, if the plant cell is exposed to a hypotonic solution for an extended period, the excessive swelling and turgor pressure can become detrimental. The continuous influx of water can cause the cell to reach its maximum capacity, and the pressure can damage the cell wall, ultimately leading to the wilting of the plant.

With the exception of a few viruses, the majority of living things employ RNA to carry out the genetic instructions recorded in DNA.
However, it has long been believed by many who study the origins of life that RNA was the original genetic material. The DNA's linear nucleotide sequence contains the genetic information.
A hydrogen bond between the G-C and A-T base pairs holds the two complementary strands of nucleotides that make up each DNA molecule's double helix together. Since RNA appears to have been the earliest molecule involved in heredity, it had all the necessary mechanisms for storing and expressing genetic information before DNA even appeared on the scene.

true/false: competitive inhibition binds to a remote area on the enzyme and changes the conformation of the substrate-binding pocket while allosteric inhibition binds directly to the active site and prevents any other molecules from binding.
False. Cutthroat hindrance ties straightforwardly to the dynamic site of a chemical and rivals the substrate for restricting, consequently keeping the substrate from framing a complex with the catalyst.
This kind of restraint brings about an adjustment of the substrate-restricting pocket, and hence, the conformity of the protein.
Allosteric restraint, then again, doesn't tie to the dynamic site, yet to a distant region on the catalyst, known as the allosteric site. The limiting of the allosteric inhibitor changes the conformity of the compound, prompting a change in the fondness of the substrate-restricting pocket, to such an extent that the substrate is less inclined to tie. Allosteric restraint can likewise influence the movement of different chemicals in a similar metabolic pathway.

what is the most important factor in determining if a terrestrial planet has liquid surface water?
Answer:
The most important parameter for Earth-like life is the presence of liquid water, which directly depends on pressure and temperature. Temperature is key both because of its influence on liquid water and because it can be directly estimated from orbital and climate models of exoplanetary systems.
Explanation:
The search for habitable worlds beyond our solar system is a major focus of modern astronomy. One key factor in the search for habitable planets is the presence of liquid surface water, which is a necessary condition for life as we know it. There are several factors that can determine whether a terrestrial planet has liquid surface water.
The most important factor in determining whether a terrestrial planet has liquid surface water is the distance of the planet from its parent star, or its "habitable zone." The habitable zone is the region around a star where conditions are just right for liquid surface water to exist. If a planet is too close to its star, it will be too hot for liquid water to exist, while if it is too far away, it will be too cold.
Other factors that can affect the presence of liquid surface water on a terrestrial planet include its size, mass, and composition. For example, if a planet is too small or has too little mass, it may not have enough gravity to retain an atmosphere, which is necessary for the formation and maintenance of liquid surface water. Similarly, if a planet is too massive, its atmosphere may be too thick, causing a runaway greenhouse effect that can lead to the evaporation of any liquid water.
The composition of a planet can also affect the presence of liquid surface water. Planets with a large amount of water in their interiors may be more likely to have liquid surface water, as the water can be released through volcanic activity or other processes. In addition, the presence of a magnetic field can help to protect a planet's atmosphere from the solar wind, which can strip away atmospheric gases and cause the loss of liquid water.
In summary, while there are several factors that can determine whether a terrestrial planet has liquid surface water, the most important factor is the distance of the planet from its parent star, or its habitable zone. By considering these and other factors, astronomers can search for habitable worlds beyond our solar system and increase our understanding of the potential for life in the universe.

We do not know what the primary cause of cancer is at this time. Here option D is the correct answer.
Cancer is a complex disease that can result from a combination of genetic and environmental factors. While exposure to carcinogens in the environment and the aging process can contribute to the development of cancer, it is not accurate to say that these factors are the main cause of cancer.
DNA replication is a crucial process that occurs in all cells, and when it no longer works properly, it can lead to the development of cancer. However, it is also not accurate to say that DNA replication no longer working properly is the main cause of cancer.
There is still much that is not understood about the causes of cancer, and scientists and medical researchers are actively working to uncover the underlying mechanisms that lead to this disease.

How does ATP store and release energy ?
By transferring a phosphate group to another molecule, ATP is able to fuel cellular operations (a process called phosphorylation).
Certain enzymes are responsible for carrying out this transfer, which connects the cellular processes that need energy to the release of energy from ATP.
When the cell needs energy, ATP can be taken out and utilised to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. Similar to this, plants use ATP molecules to store the energy they obtain from light during photosynthesis.
The pyrophosphate bond, which is located between ATP's final two phosphate groups, is where this chemical energy is kept. The third phosphate group is broken down by ATP when the cells require energy to carry out any task, releasing a significant quantity of energy that was previously bound in the third and second phosphate group's link.

avian influenza ha binds more tightly to 2,3-linked sialic acid. why are humans less susceptible to infection by avian influenza than they are to human adapted flu viruses?
Humans less susceptible to infection by avian influenza because human-adapted influenza viruses bind more tightly to the 2,6-linked sialic acid that is present on the surface of cells in the human respiratory tract.
Avian influenza viruses bind more tightly to 2,3-linked sialic acid, which is a type of sugar molecule that is present on the surface of cells in the respiratory tract of birds. This tight binding to 2,3-linked sialic acid is one of the reasons why avian influenza viruses are able to infect birds so effectively.
When an avian influenza virus infects a human, it may not bind as tightly to the 2,6-linked sialic acid on human cells as it would to the 2,3-linked sialic acid on bird cells. As a result, the virus may not be able to replicate as efficiently in human cells and may not cause as severe an illness as a human-adapted influenza virus would.
It is important to note that some avian influenza viruses can cause serious illness in humans and that the severity of illness can vary depending on the specific strain of avian influenza virus and the health of the person who is infected. For this reason, it is important to take precautions to prevent the spread of avian influenza viruses, such as avoiding close contact with infected birds, washing your hands frequently, and wearing protective clothing when handling poultry.
