A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups
vitfil [10]

Answer:

geographical isolation

Explanation:

Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.

There are two mechanisms of reproductive isolation:

  • Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation,  geographical isolation and behavioral isolation.
  • Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.

<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>

Describe how greenhouse gases contribute to climate change
vladimir1956 [14]
Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earths conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

hydrosphere and biosphere

Explanation:

The spheres of the Earth are lithosphere, biosphere, atmosphere, hydrosphere etc. Hydrosphere refers to the collection of all the water bodies on the surface of the Earth e.g oceans, lakes, rivers etc. On the other hand, biosphere refers to the collection of life on Earth e.g plants, animals, microbes etc.

In this question, Water availability is said to impact plant growth and the animals who depend on plants for food. These water availability and the living organisms (plants and animals) it impacts are interactions between the HYDROSPHERE AND BIOSPHERE.
