With biology! i really appreciate it! you. questions 46 & 47

47. It is the biodiversity on Earth that allows (at the moment) for animals, plants and humans to share the planet- if one species is destroyed, several, maybe even hundreds more, may follow.

Biodiversity is important because certain organisms have economic value (such as rainforest plants being made into medicine), they have value to the ecosystem (think of their spot on a food web), and they are a source of natural beauty and recreation.

Sometimes diseases or insects can wipe out a food crop. Having avariety of plants helps prevent widespread dead plants.

Biodiversity is the representation of the millions of different species on the earth and the genetic diversity within these species. Biodiversity is important because humans depend on animals and other species to live and grow and much as animals and other species depend on humans to live and grow. It's important because it is based on the evolution of other species.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
