The esophagus, a tube that carries food to the stomach, is constantly being scraped as food travels through it. Why does the eso

phagus not deteriorate through a person’s lifetime? Cells can anabolize the food prior to entering the esophagus. Cells are constantly dividing and replacing old or damaged cells. Cells promote a fluid to build up along the esophagus to reduce friction. Cells build a type of protein called enzymes that act as an armor.

The esophagus does not deteriorate throughout a persons life due to cellular reproduction. When the cells are scraped off by the food, mitosis, or cellular division occurs resulting in two daughter cells from one which will eventually replace the missing cells.

Please someone do this, i hate biology :(

Answer:

C - Natural selection is causing larger bird beaks.

E - Because the seed hardness has increased the birds need bigger beaks to crack them.

R - This means the birds with larger beaks are not able to crack the seeds, this causes starvation and the birds that have small beaks die as a result. However, birds with larger beaks are able to crack the seeds and eat. Those birds can then reproduce and produce more birds with larger beaks. So the population of large bird beaks has increased, but the population of small bird beaks has decreased.

How do invasive species disrupt non-native ecosystems?
Sloan [31]
There are many ways they can disrupt their new environments.

They can often carry diseases or parasites that native species are unequipped for. A good example of this is cats being brought to Australia, a continent with no native felidae. Cats are one of the main carriers of toxoplasmosis and many species in Australia had not evolved alongside felidae and were relatively unequipped to handle these parasites if their immune system was vulnerable.


They can also cause issue simply because they are so different, and the animals and plants living I. These areas are simply unable to defend themselves or keep up as a result. Such as pigs (and other animals brought over by humans) eating dodo bird eggs (these birds roosted on the ground) and domestic cats overhunting for sport.

Hope this helps a bit! It's a pretty broad topic and definitely one worth researching even more
