A trophic web is an interaction between different organisms in which energy transference occurs. 1) food chain, 2) autotroph, 3) heterotroph, 4) trophic level, 5) herbivore, 6) carnivore, 7) omnivore, 8) detritivore, 9) food web, 10) biomass.
What is a trophic web?
The trophic web is the interaction between different organisms involving the transference of energy when some of them feed on the other ones.
Organisms occupy different trophic levels in the web. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heterotrophs-: herbivores and carnivores.The last links are the decomposers that degrade organic matter from dead organisms.A trophic web is composed of different food chains. Several food chains interconnected create a trophic web (food web).
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

A hurricane blows across a caribbean island. the storm flattens trees, drowns or washes away a large number of plants and animals. as a result of the storm, carrying capacity of the island is temporarily reduced for many of the island species
Answers
Answer:
The storm is a density-independent limiting factor, because population size and density do not alter the storm's effect
Explanation:
The system parameter that has the potential to significantly alter the output factor is referred to simply as the limiting factor.
The density-independent main limitation could be an earthquake, thunderstorm, flood, or storm. These natural disasters can destroy all animals, regardless of population size.
Whatever the population size, the storm is a density-independent limitation force that will wipe all plants and animals.
As a result, it is a density major limitation since it has an impact on population growth. By reducing the range of animals and plants that are found there, these causes also limit the area's biodiversity.
But over time, the both plant as well as animal populations that survived increase once more and support the formation of a comparable ecosystem in the region.

How will changes in arterial PO2 impact ventilation?
Answers
The minute ventilation increases as PaO2 decreases. Regarding PaCO2, it is mediated over a few seconds by peripheral chemoreceptors. arterial oxygenation, unlike PaCO2, has little impact on cerebral chemoreceptors.
What clinical importance does PO2 have?The partial pressure of oxygen, or PO2, measures how much dissolved oxygen gas is present in the blood. It essentially assesses how well the lungs are able to draw oxygen from the air into the bloodstream. Increased pO2 levels are related to: increased oxygen content of the air being breathed.
The patient is well oxygenated if pO2 and SaO2 values are normal or slightly increased; To identify whether acidosis or alkalosis is present, take note of the pH level. A pH of 7.35 and a pH of >7.45 suggest acidosis and alkalosis, respectively.

Inactive X chromosome in cells with The Lyon hypothesis states that in cells with multiple X chromosomes, all but one are inactivated during mammalian embryogenesis. This happens by chance early in mammalian embryonic development , but in some extraembryonic mammals in marsupials and some placental mammals where the sperm X chromosome is always inactivated.

Barr bodies can be seen in interphase nuclei as dark blobs in contact with the nuclear envelope. Barr bodies are found in neutrophils at the edge of the nucleus.

The size of proteins what is the approximate molecular weight of a protein with 682 amino acid residues in a single polypeptide chain?
Answers
The Molecular weight of a 682 amino acid-long protein would be around 75kDa.
How can you determine a protein's molecular weight from an amino acid?When the amino acid sequence of a protein is known, we may roughly calculate the protein's molecular weight by multiplying the average molecular weight of the amino acids by the total amount of amino acids that make up the protein. An amino acid's molecular weight is typically 110 Daltons (Da). The total of the products of the number of picomoles of each amino acid multiplied by the associated molecular weight will give you the concentration of peptide or protein in the original sample.Given the number of amino acids that make up a protein, a common method to determine its molecular weight is to multiply that number by the typical weight of a 110Da amino acid.So the MW of a 682aa-long protein would be around 75kDa.

Answers
The best example of diffusion in plants is the transport of carbon dioxide and oxygen through the stomata. In Animals glucose and oxygen are necessary for the normal functioning of cells, therefore these substance reaches the cells through the blood and diffuses out from the blood into the cells.
How does oxygen from the lungs get into the bloodstream?The lungs have tiny sac-like structures known as alveoli at the end of each bronchiole. Alveoli is the point where the gas exchange takes place, oxygen is delivered to the lungs and the carbon dioxide is eliminated from the bloodstream to the lungs and out of the body.

Most autotrophs use a process called photosynthesis to make their food while the heterotrophs do not.
Autotrophs produce food for themselves using photosynthesis, but they also produce enough to sustain other forms of life. These three groups provide all of the food that the majority of other creatures create. Autotrophs are the "producers," starting the food chains that sustain all life. The "Food Chains and Food Webs" idea will cover food chains.
As heterotrophs are unable to produce their own food, they must consume it or absorb it. Heterotrophs are also referred to as consumers because of this. All types of animals, fungi, as well as numerous protists and bacteria, are consumers.
They might eat other heterotrophs, autotrophs, or organic compounds produced by other creatures. The diversity of heterotrophs is enormous, and they can seem far more fascinating than producers.
