25 points what is the state of michigan doing to fix the problem of purple loosestrifes? (invasive species) i need a source( from where did you get the answer)

The purple loosestirfes are a beautiful wild plant. They are native of Eurasia, more specifically Macedonia, and they have been brought by accident in North America. Once there, this plant managed to spread out very quickly in the wetlands, rapidly overtaking the territory of the native species. The problem became very serious, especially in Michigan, so the scientists from the universities started to make projects in order to stop this invasive species from destroying the local flora and even fauna. The biggest steps made have been by releasing natural enemies of this plant where it has spread out. The natural enemies are all insects, and they have selectively been released to be only harmful tot he purple loosestrife, but not the other plants. The effects have been good, as the insects managed to reduce the density of this invasive species by a lot, opening up space for the native species to thrive again.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
