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.
Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.
Tiktaalik roseae was discovered in sediments on Ellesmere Island in Nunavut, Artic Canada (Ahlberg and Clack, 2006). The sediments it was found in are from what is known as the Fram Formation, which is thought to be deposits of lowland streams (Murphy, 2005). hope it helps
