Ascientist is studying the biodiversity of an ecosystem that has a cool climate. the scientist counts the number and types of organisms in a 5 foot by 5 foot area. she finds that the ecosystem has very low biodiversity. another scientist studies the same ecosystem. he counts the number and types of organisms in a 1,000 foot by 1,000 foot area and finds that the ecosystem has high biodiversity. what  likely  caused these different results? the scientist who found high biodiversity observed fewer niches. the scientist who found high biodiversity observed more plants than animals. the scientist who found low biodiversity studied the ecosystem on cold days. the scientist who found low biodiversity studied too small of an area.

The answer is the last option: "The scientist who found low biodiversity studied too small of an area."

Explanation:

To asses the biodiversity of an ecosystem, the area that you sample has to be representative of it. The scientist should sample more plots (areas) in order to record all (or most) of the species that can be found in the ecosystem. Additionally, it is necessary to sample all different types of areas within the ecosystem. Different types of areas have different microclimates; therefore, different species are associated with different types of areas or microclimates.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.

explanation:

its temperature is increasing. this causes molecular vibrations to increase.
