Answer:
Eutrophication
Explanation:
When a body water lies in close proximity to any agricultural land, there are high chance of it receiving nutrient from the surrounding land in rainy season. The rich nutrient run off from these land parcels, mixes with the water of existing water body and make it extremely rich in growth nutrients. The excess of nutrients causes uninterrupted growth of algae and lead to algal boom. Oxygen in such water bodies depletes at a fast rate due to the increased productivity thereby harming the water animals living in it.
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection
Explanation:
You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.
Gel electrophoresis is used in a device that compares the DNA of organisms to each other.
When gel electrophoresis is used, bands of DNA are pulled to polar ends, creating a line of bands of DNA varying in thickness. Some bands may attract more than others which then makes this line of DNA bands. This occurs with several samples of DNA used in a device with gel electrophoresis. The lines of bands that are the most similar are the ones that are the most related to each other. If the line of bands is identical to another line of bands, it is the same organism.
