Which is a shorter process - (circle one) selective breeding or natural selection?
andrey2020 [161]

Answer:

Selective breeding.

Explanation:

Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.

Why do you think scientists want to be able to forecast space weather?
DiKsa [7]

Answer:

Scientists would most likely want to forecast space weather in order to know if it is safe for not only to lift off into outer space, but to be able to help astronauts in any case of emergency if something were to happen in the future.

Such as debris of small rocks that could pass by, so then astronauts would have to stay in the shuttle. To be protected from it.

In any case, scientists want to forecast the weather in outer space in order to protect astronauts, from any incoming dangers.
