Answer:
substitution is the Answer
Answer:
mamals and birds
Explanation:
The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Different animals have bones that appear very similar in form or function and seem to be related.
Examples
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.
The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.
Graphs attached
Answer:
Graph D
Explanation:
Primary succession is when a population arises from an environment that was previously entirely devoid of any living things.
Therefore, the number of living things would start at 0. Once a pioneer species colonizes the area, it makes the soil more fertile. This makes it a more suitable environment for other species to grow. Over time, the number of species increases as the community becomes more complex, until it reaches its peak and plateaus at its final composition, which is called the climax community.
This is represented by Graph D
The correct answer would be: B. I hope this helped!
