Answer:
Ocean acidification: Ocean acidification refers to the decrease in the pH of ocean water.
The pH of ocean water decreases due to the increased in the carbondioxode emissions in the atmosphere because of the burning of fuels. This carbondioxode is dissolved in the ocean water and forms carbonic acid. This carbonic acid is responsible for increasing the pH of ocean water. In one and half century, there is 30% increase occurs in the acidity of ocean water.
Answer:
Haploid cells
Explanation:
When a cell undergoes mitosis, it duplicates its genetic material, separates the two sets, and then, via cytokinesis, splits into two genetically identical cells. meoisis is a reduction division that produces haploid cells. Haploid cells re essentially required in gametes. Thus, meoisis produces haploid cells.
maybe it's called osmosis?
