Fish and coral have a symbiotic relationship, where fish benefit from the shelter and food provided by the coral, and coral benefits from the waste removal and nutrient delivery provided by the fish.
A symbiotic relationship is a type of interaction between two or more species where both species benefit from the association. This can take various forms, such as mutualism, where both species receive benefits; commensalism, where one species benefits and the other is not affected; and parasitism, where one species benefits at the expense of the other.
Examples of symbiotic relationships include the relationship between bees and flowers, where bees collect nectar and pollen and pollinate the flowers, and the relationship between cattle and cattle egrets, where cattle stir up insects while grazing, making them easier for the birds to catch. The diversity of life on Earth is largely dependent on symbiotic relationships, and they play an important role in maintaining the balance of ecosystems.

Answer: 1- Carried on cargo crates
2- Transported in or on ship
4- Hidden inside produce or meat
5- Carried on clothing or in luggage
6- Intentionally introduced by humans
A species introduce into the new ecosystem is the non-native species. This species will affect the life cycle of the native species both positively or negatively. Positively: The new species may be more productive and compatible for mating with the native species.
Negativity: The new species may interfere with the life cycle of native species. Such species may compete for resources with the native species.
The species may be transferred to the new ecosystem by carried on cargo crates, transported in or on ship, hidden inside produce or meat, carried on clothing or in luggage, and intentionally introduce by humans for their own benefit and use.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Basically there are four processes that takes place under "MEIOSIS". And they are :
In prophase, chromosomes become visible and crossing-over occurs, then nucleolus disappears and the meiotic spindle forms, then the nuclear envelope disappears.The duplicated homologous chromosomes pair, and crossing-over (the physical exchange of chromosome parts) occurs.
Metaphase process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During metaphase, the cell's chromosomes align themselves in the middle of the cell.
Anaphase I begins when the two chromosomes of each bivalent separate and start moving toward opposite poles of the cell as a result of the action of the spindle.
In telophase a homologous chromosome pairs reach the poles of the cell, nuclear envelopes form around them, and cytokinesis follows to produce two cells. After cytokinesis, each of the two progeny cells has a nucleus with a haploid set of replicated chromosomes.
A vaccine is known to be the biological preparation that are known to provide acquired active immunity to a body against a particular disease. It consists of agents that is similar to disease causing microorganism, it is often made up of weakened, killed form of microbes or its toxin or its surface protein.
Vaccination is the treatment which makes body stronger against a particular disease. It helps body to fight against infection by making antibodies against pathogen.
The steps of vaccination are:
A weakened or dead form of the pathogen is injected into the body
The pathogen is not strong enough to cause disease but its presence in the body signals the body to protect itself against the pathogen
White blood cells produce antibodies that destroy the pathogen
Pathogens enter the body and the body can remember the pathogen using memory cells, destroying the pathogen
Vaccination may be defined as a process through which a dead or inactivated form of a pathogen is injected into the body for the purpose of stimulating the immune system.
Pathogens may be defined as those microorganisms which are responsible for the causation of diseases.
The correct order of the steps for the vaccination is given below:
Therefore, it is well described above.
