I think we all can agree, water and land are badly polluted. To stop pollution, more community service, more trash cans and recycling bins, and more laws. As water and land collide (think about the beach) more pollution from the waster is washing up to shore, trash including, soda cans, water bottles, paper, silicone, and even beached animals. Not only does water pollute the land but the land pollutes the water. Including, beach toys, towels, drinks, cellphones, and many more...
The correct answer is C. This part is called the epithelium.
It is the muscular coat which consists of inner circular and outer longitudinal smooth muscle. Its main work is peristalsis.
To propel urine. The outer layer is the mucosa which has transitional epithelium that continuos with the lining of the renal pelvis and also the urinary bladder.
This layer of its work is to secrete mucus which protects and coats the surface of the cells.
No, they're probably thinking that you are a player. btw is this Ella Hicks!?
Answer:
Speciation didn't occur over the past 10,000 years
Explanation:
We conclude this, since the two populations could mate (if speciation occurred, there would be no reprodution).
For example, in allopatric speciation which occurs as a result of geographic isolation, the part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed (reproduction between them) which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
