Una ambulancia que esta a ( 10,04km) del hospital hace sonar su sirena. Calcula el tiempo que tardará en oír la sirena un doctor que se encuentra en la puerta de urgencias del hospital. Recuerde que la velocidad del sonido en aire es de 340 m/s

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

a physical change is being made.
