More likely the answer A if it not im sorry
<h2>
short definition:</h2>
<u><em> a species is a population or groups of populations that can potentially interbreed freely within and among themselves.</em></u>
<u><em /></u>
<em><u> Subspecies, are subgroups within a species that have different traits </u></em>
<h2>
long definition</h2>
<em><u>A species is a group of organisms that (in the case of sexually reproducing organisms) can freely interbreed, producing fertile offspring. This definition has its problems, but overall, it encompasses the meaning of the word “species” in biology.</u></em>
<em><u></u></em>
<em><u>A subspecies is, as the name implies, a smaller population within a species that share a particular common trait. Usually a sub species is at least partially genetically isolated from it’s parent species, so that interbreeding is less likely to occur. Most often a sub species is physically separated from the rest of the species, and may have some specific physical differences from the rest of the species. However, they are still able to interbreed with members of the parent population.</u></em>
It is answer B, that is what I think it is
Answer:
Scientists believe that plate tectonics is an example of an internal force that changes the Earth’s crust.
Plate tectonics is a theory that describes the motion of seven large plates, and many other smaller plates of the Earth's lithosphere. When they collide they can make mountains or we can feel their motion as earthquakes. Their motion is responsible for the continental shift and it made our continents look the way they look today.
Answer:
50-64
Explanation:
China is the nation with the largest population in the world, and that has been the case throughout all of the written history, and probably even before that. The country had very large birthrates, which was leading to rapid growth to the population. Because of that, there was even a law that restricted the families as to how many children they can have. Because of that law, the population of China started to gradually age, so the percentage of the younger age groups has been declining, while the percentage of the older age groups has been on the rise. This has led to the age group of 50-64 to account for 120 million people in China, a percentage that has grown almost twice compared to several decades prior to that.
