Sound waves cannot travel through a vacuum. This is because sound waves move by actually compressing molecules--therefore in a vacuum it would be impossible for sound to travel. This is also why no sound can be heard in space.

In most natural populations rapid exponential growth is unsustainable. As populations
adell [148]
Answer:
Carrying capacity is defined a the ability of the natural ecosystem to take care of the environment which does not necessarily cause the resistance in population increase.
Explanation:
The earth indeed has a mechanism of delivering changes to the system and keeping it intact but as the case of the rapid growth of population arises the mother nature sees this as an exponent of unsustainable growth as the resource used to sustain large populations is no longer available or are exhausted.
A population increase so does the carrying capacity and workload of the natural environment which at the time gets slow due either due to the man's artificial technology or the natural process like hurricane or earthquake itself.
But seeing the nature as providing possibilities for the existence of the societies throughout ages and hence trying to maintain its originality may break those activities that it considers resistance as several biotic factors like predators, disease, competition, and lack of food.

Relate sexual reproduction to evolutionary forces
kari74 [83]
Sexual production is a means of recreating more of a species. Once there is a gene change whether for the good or bad, and solely if the organism survives to reproduce its gene, then it will be passed on to its children and going further on until there is a large amount of a species with that specific gene. This species evolved. Evolution occurs because of gene changes.
