The most important factor that limits the size of a cell is the ability of the cell to transport materials efficiently into and out of the cell. In this case the size of a cell should have a particular form in order to export and import material.
Bioticas
Bioticas son seres vivientes que necesitan oxygeno o dioxido de carbono por whemplos seres humanos, plantas o bacterias.
Abioticas son seres que no son viviento que no necesita oxigeno como agua, el viento y precipitación
Medical assistance safeguards the process of birth. The process of giving birth poses serious risk to both mother and child. There are a number of complications that can occur during the process that can cause the death of both mother and infant.
Medical assistance reduces the risk and ensures a safe delivery by being on hand in the event that a complication may arise. The infant mortality rate and the number of mothers who die in childbirth have been significantly reduced because of medical assistance.
Answer:
Analogous structures
Explanation:
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.
Analogous structures are examples of convergent evolution, where two organisms separately have to solve the same evolutionary problem – such as staying hidden, flying, swimming, or conserving water – in similar ways. The result is similar body structures that developed independently.
In the case of analogous structures, the structures are not the same, and were not inherited from the same ancestor. But they look similar and serve a similar purpose.
For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.
