Answer:
The Answer is Small Intestine
Explanation:
A small intestine is attached to the stomach and goes all the way to the anus. Despite it's name it is not really small. It was average size. 20 feet long and about one inch thick in diameter. However, the size can greatly vary in some people from as small as 10 feet to as large as 34 feet.
As our food passes through the small intestine, small fibers start to absorb as much nutrients and minerals it can from the food.
Along with humans it is found in every four-limbed animal and is particular large in herbivors.
DNA replication needs to occur because existing cells divide to produce new ones . It needs to be copied before cell division so each new cell created can receive a new full set of “instructions”
Answer:
Plants take nitrogen from the soil by absorption through their roots as amino acids, nitrate ions, nitrite ions, or ammonium ions. Plants do not get their nitrogen directly from the air. ... Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea.
Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.
