It should be. the core if located there aha.
Answer:
d. are no older than 600 million years
Explanation:
Life on Earth appeared relatively early and in very hostile conditions, approximately 3.5 billion years ago, which is only 1 billion years after the formation of Earth. For the first multi-cellular animals to occur though, it took a very long time since life occurred, as the fossils suggest that they only appeared around 600 million years ago, whole 3.9 billion years later than the first uni-cellular lifeforms on Earth. Once the living organisms managed to get to a faze where they are multi-cellular, a real explosion in diversification of the living organisms occurred, and the evolution was rapid. Very soon complex organisms start to appear around the planet, eventually leading to the plants, fish, insects, sinapsids, dinosaurs, mammals, reptilians.
The earth was supposedly formed <span>by collisions in the same giant disc-shaped cloud of material that </span>formed<span> the Sun. Gravity slowly gathered all the gas and dust together into clusters that became asteroids and small early planets called planetesimals</span>
Answer: First trophic level
Explanation:
The autotrophs are the organisms which prepare their own food by the process of photosynthesis. The group of autotrophs includes the plants and some microbes. The trophic levels are the levels or steps in the energy pyramid which represents the increase in complexity of the organisms and the decrease in energy with the rise of the trophic level.
The autotrophs are included in the first level, as they are capable of producing their own food and exhibit highest energy in the energy pyramid. They are called as the producers.
Answer:
Both A & C would be your answer!
Explanation:
Most volcanos are located along divergent plate boundaries and convergent plate boundaries.
