Answer:
Los órganos homólogos, análogos y rudimentarios o también llamados vestigiales, se diferencian significativamente por su función, estructura, apariencia y origen. ... Mientras que los rudimentarios o vestigiales son aquellos que no poseen función alguna ya que se ha perdido con la evolución.
Explanation:
The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.
In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.
A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.
Ecosystem
Ecosystem refers to the community made up of all the living organisms (biotic component), their physical environment and all their interactions in a given space.
The biotic and abiotic components of the ecosystem are linked with the help of energy flows and nutrient cycles.
Answer:
The pumping of the heart involves the alternate contraction and relaxation of the chambers of the heart. The upper chambers of the heart are called at atria and the lower chambers of the heart are called ventricles.
The statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
<h3>What do you mean by Biodiversity?</h3>
Biodiversity may be defined as the sum total of all the living organisms living in a particular ecosystem.
As the number of species increases, biodiversity also increases because both are directly proportional to one another.
While the species enhancement negatively impacts the sustainability of the environment.
Therefore, the statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
