Producers, because according to food pyramid, only 10% of energy is passed onto the next layer, where the other 90 is passed off as heat, so there must be more producer in order to sustain the ecosystem.
Answer:
Answer is option A.
Vestigial features are fully developed and functional in one group of organisms but reduced and function less in a similar group.
Explanation:
- Vestigial structures are anatomical features such as cells, tissues or organs in an organism that are previously functional and performed some important functions in the organism but no longer serve any functions in the current form of the organism and become useless as a result of a large evolutionary change. Examples include the coccyx or the tailbone in humans, the pelvic bone of a snake, wisdom teeth in humans, nipples in human males, the wings of flightless birds such as kiwi, ostrich, etc.
- Homologous features are the features that are similar in different organisms having similar embryonic origin and development and are inherited from a common ancestor that also had that feature. Also, they might have different functions. An example is the presence of four limbs in tetrapods such as crocodiles, birds, etc.
- Analogous features are the features that are superficially similar in different organisms but had separate evolutionary origins i.e., different in origin, but similar in function. An example includes the wings on a fly, a moth, and a bird where the wings were developed independently as adaptations to perform the common function of flying.
- Polygenic features are the traits or features that are controlled by multiple genes that are located on the same or different chromosomes and are also affected by the environment. These features do not follow Mendel’s pattern of inheritance and are represented as a range of continuous variation. Examples of polygenic traits or features include skin color, height, hair color, eye color, etc. For example, there is wide variation in the human skin color (from light to dark) and height (short or tall or somewhere in between).
- Sympatry describes a species or a population that inhabit the same geographic region at the same time. In sympatric speciation, new species are evolved from a surviving ancestral species while both the species inhabit the same place at the same time i.e., in a single population, reproductive isolation occurs without geographic isolation.
Answer:
5 metros.
Explicación:
Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.
If a defibrillator manufacturer claims that its device terminates ventricular fibrillation on the first shock 95% of the time, you should: recognize that this does not mean it will save more lives.
<h3>Defibrillator </h3>
The purpose of defibrillators is to restore a normal heartbeat by shocking or sending an electric pulse to the heart. They are employed to stop or treat irregular heartbeats that are too slow or too fast, or arrhythmia. Defibrillators can also restart the heart's rhythm if it stops suddenly. Defibrillators operate differently depending on the type. People who are having cardiac arrest can be saved by using automated external defibrillators (AEDs), which are increasingly commonplace in many public areas. These gadgets can be used in an emergency by unskilled witnesses. People who have a high risk of developing a life-threatening arrhythmia may benefit from using other defibrillators to avoid sudden death.

Gene. A segment of a DNA molecule that codes for a particular protein and determines the traits of the individual. A gene is the basic unit of heredity in a living organism
