The ferric ions' cytochrome oxidase in the mitochondria makes a reversible chemical bond with cyanide. By preventing the conversion of oxygen to water, this essentially stops cellular respiration.
What is the role of cyanide in cellular respiration?Heme-containing proteins include Fe3+, which cyanide binds to. As a result, the electron transport chain's terminal cytochrome complex IV is inhibited.
Cyanide's blockade of complex IV depletes ATP, which leads to cell death.
Because the molecules are so small and can disperse quickly throughout the entire body, cyanide can kill so quickly by damaging all major organs and tissues in a short period of time.
Therefore, electron transport system is affected by cyanide in cellular respiration.

Explain how fitness can change the allele frequency of a population. PLZ no link
Answer:
Natural selection can cause microevolution (change in allele frequencies).
Explanation:
With fitness-increasing alleles becoming more common in the population.
Fitness can affect the survival and reproduction rates of individuals with different alleles, leading to differential contribution to the next generation and changes in the frequency of these alleles in the population.
What is fitness?Fitness is a measure of the reproductive success of an individual within a population. The fittest individuals are those that are most successful at passing their genes on to the next generation. When the environment changes, the selective pressures on a population also change. This can lead to changes in the relative fitness of different individuals, and thus changes in the allele frequencies of a population over time.
For example, if a population of birds lives on an island with small seeds, those birds with small beaks may be more fit than those with larger beaks. This is because they are better adapted to the environment and can more easily obtain food. Over time, the frequency of the small-beaked allele will increase in the population, while the frequency of the large-beaked allele will decrease.
Thus, fitness can drive changes in the allele frequency of a population over time by favoring those individuals with alleles that are better adapted to the environment.

Answer:
A close, interdependent relationship between two organisms is called SYMBIOSIS . There are three main types of symbiotic relationships. In MUTUALISM, both organisms benefit from the relationship. When one organism benefits but the other is harmed, their relationship is called PARASITISM. Occasionally, two organisms have a relationship where one organism benefits and the other is neither hurt nor helped. This type of relationship is called COMMENSALISM.
The type of relationship where one organism benefits and the other is neither hurt nor helped is called commensalism.
What is commensalism?In biology, commensalism is a connection between members of two different species in which one species uses the other for food or other purposes without causing the other any damage or gaining anything in return.
The commensal, or species that gains from the connection may take resources from the host species, which is unharmed, or find refuge, support, or means of movement. Frequently, a bigger host and a smaller commensal are in a commensal relationship.
The commensal species may exhibit significant morphological adaptation, whilst the host organism is virtually unaffected by the contact. Contrasting this connection with mutualism, which benefits both species,
A well-known illustration of a commensal is the remora (family Echineidae), a fish that travels in close proximity to sharks and other fish. Remoras have developed a flat, oval-sucking disc structure on top of their heads that cling to the bodies of their victims.
Remoras and pilot fishes both eat the leftover food from their hosts. Bird species like the magnificent egret (Ardea alba), which feeds on insects discovered by grazing animals or on soil creatures stirred up by plows, are other instances of commensals.
Therefore, this type of relationship is called commensalism.
