Due to the fact that carbon is expelled as soon as it is absorbed, the resident time would be zero.
What is a healthy carbon cycle?The carbon cycle is essential to life on Earth. Because nature tends to keep carbon levels in balance, the amount of carbon that is naturally released from reservoirs equals the amount that is naturally absorbed by reservoirs. By maintaining this carbon balance, the planet can support life indefinitely.
Why is it important for the carbon cycle to remain balanced?The carbon cycle appears to sustain a balance over time that prevents all of the carbon on Earth from either entering the atmosphere (as is the case on Venus) or from being totally stored in rocks. The Earth's temperature is largely maintained by this equilibrium.

What is plant cells?Plant cell, the basic unit of all plants. Plant cells, like animal cells, are eukaryotic, meaning they have a membrane-bound nucleus and organelles. The following is a brief survey of some of the major characteristics of plant cells. For a more in-depth discussion of cells, see cell.
Unlike animal cells, plant cells have a cell wall surrounding the cell membrane. Although often perceived as an inactive product serving mainly mechanical and structural purposes, the cell wall actually has a multitude of functions upon which plant life depends. Plant cell walls are composed of cellulose, which sets them apart from other organisms with cell walls, such as bacteria (peptidoglycan) and fungi (chitin). Algal cell walls are similar to those of plants, and many contain specific polysaccharides that are useful for taxonomy.

how is energy lost in a food chain?
Answer:
90
Explanation:
Not all the energy is passed from one level of the food chain to the next. About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.
Answer:
Energy can be lost in a multitude of ways in a food chain. 90% of energy is usually lost either in the form of heat, through movement while using energy, or materials that are not entirely consumed by the consumer.
Explanation:
Only about 10% of energy is retained after a consumer eats a lower level on the food chain. Further explained, heat is released during respiration, which is essentially energy being lost.
Animals also have metabolism and growth, which require energy of their own. So, not all energy in a food chain can be retained for the animals to use.
Who demonstrated that dna is the genetic material of the t2 phage?
Classical experiments carried out by Hershey and Chase proved that the T2 phage's genetic makeup is DNA.
Because DNA seemed to be an inert molecule and because it is found in the nucleus, it was thought that since it is there it serves as phosphorus storage. Despite the fact that DNA had been known to biologists since 1869, many scientists at the time still believed that proteins carried the information for inheritance. In their experiments, Hershey and Chase demonstrated that while most of the protein in bacteriophages, which are made up of DNA and protein, does not enter the host bacterial cell when they infect bacteria, their DNA does. DNA is the hereditary material, as demonstrated by Hershey and Chase and subsequent discoveries.

During the cell cycle the cell divides its nucleus and chromosomes during what
During the cell cycle, the cell divides its nucleus and chromosomes during the stage known as mitosis.
What is the Cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The complete process of the cell cycle is divided into two phases. They are as follows:
Interphase.M-phase (Division phase).During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
Therefore, during the cell cycle, the cell divides its nucleus and chromosomes during the telophase stage of mitosis.

Which statement correctly describes the mesosphere? (1 point) O The Northern Lights are visible in this layer. Atmospheric changes in this layer cause weather at Earth's surface. O Commercial airplanes fly through this layer. O Meteors burn up in this layer to create shooting stars.
Answer:
Meteors burn up in this layer to create shooting stars.
Explanation:
The mesosphere is a layer of the Earth's atmosphere that is located between the stratosphere and the thermosphere. It is the layer where most meteors burn up upon entering the Earth's atmosphere, creating shooting stars. The mesosphere is located at an altitude of about 50 to 85 kilometers above the Earth's surface. The layer is relatively thin and has low temperatures, and thus, it does not have much weather-related activity. The Northern lights are visible in the thermosphere, not in the mesosphere. Commercial airplanes fly through the lower layers such as the stratosphere, not the mesosphere.

Apply evolutionary psychology to explain why a child might be afraid of snakes the first time she encounters one.
Evolutionary psychology suggests that certain fears, such as a fear of snakes, may be innate in humans because they were beneficial for survival in our evolutionary history. Snakes have been a potential danger for humans for thousands of years, and encountering a snake could mean getting bitten and potentially dying from venom. Therefore, it is reasonable that humans have evolved a fear of snakes as a survival mechanism.
When a child encounters a snake for the first time, her fear response might be triggered by innate, hard-wired mechanisms in the brain that have been passed down through generations. This fear response, often referred to as "preparedness," is thought to have evolved because it helped our ancestors survive in the wild. It is a way of protecting the child from potential harm.
In summary, a child might be afraid of snakes the first time she encounters one because of an innate fear response that has evolved through natural selection as a survival mechanism.

In chapter 4 of Animal Farm, the pigs use propaganda to control and manipulate the other animals. This propaganda controls the animals' thoughts, actions, and emotions, making them more subservient to the pigs' rule.
One example of propaganda is the use of slogans such as "Four legs good, two legs bad" and "Animal are comrades" which are repeated throughout the chapter. These slogans are used to simplify and unify the animal's thinking, making them easier to control.
Another example of propaganda is the use of rewriting history, in which the pigs alter the historical records of the farm to make it appear that the pigs were responsible for the farm's successes and the other animals were not. This is used to justify their increasing power and control over the farm.

Cell Size is Limited by Surface Area
The surface area to volume ratio restricts the size of a cell since a larger cell has less surface area in relation to its size (SA:V).
Cells have varied morphologies. Each cell type contributes differently to the proper functioning of our bodies, and these contributions are made possible by the shapes of the cells. Animal cells can be found in a wide variety of sizes and forms. The maximum size of a cell is determined by the surface area to volume ratio. A smaller cell is more efficient than a bigger cell at transporting goods, including waste products.
Since cells are minuscule, only a trained eye can see them. Despite the apparent logic of an organism consisting of a single large cell, our cells are specialised and perform certain functions within the body. Furthermore, a cell's ability to grow in size is constrained by physiological factors. A cell is exceedingly small on the scale, or in terms of size, relative to other items.
