Explanation:
Answer:
- Glacial deposits and scratches in the bedrock from an ice sheet match in distant regions
- Fossils of marsupials were originally the same across South America and Australia
- Cratons match across the edges of continents
Explanation:
South America, Africa, Antarctica, and Australia were all once part of one super-continent. This super-continent has been named Gondwanaland. As the geological processes got more intensive though and Gondwanaland separated into smaller land masses, continents, which we now know as the continents on the Southern Hemisphere. There are numerous clues that confirm that these continents were once connected. Some of the clues are the matching cratons on the edges of the continents, the glacial deposits and scratches in the bedrock are also matching, lot of fossilized flora and fauna from the same species have been found in several of these continents, the marsupials in South America and Australia etc.
<span>Scientists have become concerned about deforestation due to its rapid increase in the last decade wherein more and more species are declining due to their habitat and food sources being destroyed. Taxonomists who study primarily in plant and animal groups are also concerned at how this will affect specific species of flora and fauna in effected areas.</span>
Answer:
Members of a city planning committee want to designate over 100 hectares of greenspace in the city limits as protected, natural areas. One committee member, a biologist, tries to convince the other committee members to implement a plan that maximizes biodiversity in the greenspace while reducing the likelihood of invasion by a nonnative species.
