This chemical was a white insecticide that caught national attention‚ aided to urge the passage of legislation to regulate lethal chemicals and fueled potential environmental activism in VA. This chemical outburst

1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.

A vast area of the North Pacific Ocean‚ often referred to as the “Great Pacific Garbage Vortex” is an area heavily concentrated in marine debris such as plastic and various other chemicals leaching into marine ecosystems and creating detrimental environmental and health impacts. The garage patch is divided into an Eastern patch located off the coast of California and a Western patch found off the coast of Japan‚ that work collaboratively to spin the marine debris. The North Pacific Subtropical Convergence
