Answer:
The correct answer is option d. "Humans share a deep evolutionary ancestry with other animals that can be seen in reappearing atavisms or body parts that no longer seem to have a function".
Explanation:
A vestigial organ or vestigial structure is an anatomical feature that no longer seems to have a function, but they used to serve a purpose in an ancient form of an organism in the past. Atavisms, are vestigial organs that seem to reappear after having been lost through evolutionary change. Charles Darwin's studies on the subject made him conclude that humans share a deep evolutionary ancestry with other animals that can be seen in reappearing atavisms or body parts that no longer seem to have a function. He published his studies on human vestigial organs and atavisms in his book "The Descent of Man, and Selection in Relation to Sex".
Answer:
An ecosystem that contains insects, water, algae, and birds all work together by feeding one-another.
Explanation:
Algae are typically found within water. Algae use carbon dioxide, converting water to organic matter and oxygen. They are important sources of dissolved oxygen in a water confine.
Now, since algae help water by oxygenating it, living things are able to drink the water.
..This helps the bird, since it <em>needs </em>to drink water. As all living things do.
