Pioneer species are often hardy plants with Adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration.
Answer: The Americas
Explanation:
Scientists use DNA to track the migration of humans across the planet. After a group migrates away from their ancestral homeland, any mutations that occur are not mixed with those left in the ancestral population. Therefore, DNA samples taken from __the Americas__ would have the most unique mutations, representing the most recent population to migrate to a new area.
The process by which food is grown/produced, then eventually consumed.
The answer would be birds flying to South and hibernation of some animals like chipmunks and bears.
Every year, many migratory birds would migrate to the South before the winter season comes. Another sign of seasonal changes, some animals would hibernate during the winter and wake up when the spring season comes.
Answer:
B) gravity, lichens and moss, tree roots
Explanation:
In this mountainous area of Canada, weathering of rocks occur due to the force of gravity which increases the speed of rolling rocks and causes weathering of rocks into small pieces. These rocks have hard surfaces so only moss and lichens grow on these surfaces. The reason behind the growth of moss and lichens is that they have not specialized root system like plants. Lichens also helps in the weathering of these rocks by secreting chemicals.
