A private reptile breeding facility near the Everglades was destroyed by Hurricane Andrew in 1992. This event contributed to the
Angelina_Jolie [31]

Answer:

Claim:

The increase in the population of the Burmese python in Everglades is affecting the ecosystem of said area. They are an invasive species.

Evidence:

From 1994 to 2007, the Burmese python population increased from a small number below 50 species to more than 250 by 2007. As the Burmese population increased, the mammals' population in Everglades decreased significantly and even had extincted some species. For example, from 1993 to 1999, there were 64 white-tailed deer and five red foxes, and grey foxes. Between 2003 and 2011, there were 24 white-tailed deers and 0 foxes. Overall, there is a decrease in all mammals.

Reasoning:

The increasing number of Burmese Pythons due to the release of them by pet owners and due to the destructions of a private reptile breeding facility left a high number of pythons in the wild. As a consequence, these pythons ate other animals producing an imbalance in the Everglades ecosystem. Owing to its large number and how they are harming the ecosystem, they are considered an invasive species.

Explanation:

After analyzing the information, the claim is that the increasing population of pythons harms the Everglades' ecosystem.

The evidence that supports the claim is present in the graphics, where we can see how the population of this reptile grew over the years, and the mammals' population decreased. There is specific information about the reduction in the number of mammals in the area, such as the raccoon, foxes, rabbits, etc.

After presenting the evidence, the reasoning that we can make is that the pythons are killing the other animals in Everglades. Also, we can see that they are not a native species from the area since they were released by pet owners and by a breeding facility by accident. The fact that they are harming the Everglades' ecosystem and that they are not native species makes them an invasive species.

the grand canyon was carved, separating what had once been a single population of squirrel into two seperate populations. what d
tatiyna

Answer:

They became different.

Explanation:

Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.

Why do scientist need a common system of measurement?
EastWind [94]
So when one scientist turns around and says the mass of an electron is 9.10938291×10^-31 kilograms we know what a kilogram is and so we don't get an answer that it's 32949 microsmiths as he invented his own measurement because he needed one.
