Nonpoint source pollution is a greater hazard, because scientists are not able to identify a single location the pollution came from. It is harder to find a solution if they are unable to find the source.
Hope this helps!
have a great day.
Answer:
Prophase
Prometaphase
Metaphase
Anaphase
Cytokinesis and Telophase (Yes two answers)
Explanation:
Prophase is when the chromosomes condense
Prometaphase is when nuclear envelope dissolves
Metaphase, M for middle, meaning all chromosomes line up at middle
Anaphase, A for apart, meaning all chromosomes are taken apart in half
Telophase is the formation of 2 different nuclei, and Cytokinesis splits it
Answer:
Get the atoms to press together with pressure so that they fuse.
