Answers

Invasive species can either replace an organism from the ecosystem food web or replace it.  

Explanation:

  • Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.

When is the microscope not useful?

Answers

The microscope isn't useful when you are trying to see a large object, or an object that doesn't have major detail. The main use of a microscope is to see things that the human eye cannot. For example, you try to see the structures of an ant. You can see an ant with your eyes alone, but you cannot see it very well without a microscope.

Metaphase: Chromosomes align at the equator of the cell and spindle fibers attach to each sister chromatid.

Anaphase: Spindle fibers pull the sister chromatids away from each other to the opposite sides of the cell.

Telophase: New separate nuclear membranes form around the different sets of chromosomes and the chromosomes unwind, the spindle fibers start breaking down and and the cell begins to pinch together to separate into two new cells.
