Organic farming methods enable farmers and gardeners to prepare soil in such a way that nitrogen is added naturally through nitrogen-fixing bacteria rather than nitrogen having to be added through a synthetic fertilizer. This method of growing crops saves farmers money and alleviates the problems associated with fertilizer runoff
Farmers and gardeners should use other methods to provide crops with the nitrogen they need.
Algal blooms are due to the accumulation of algae, generally Cynabobacteria and Dinoflagellates, that grow due to excess nutrients in water.
If good algae grow, they do not accumulate in the waterbodies.
Diatom Algae are good algae.
Therefore if Diatoms are grown instead of Cyanobacteria and Dinoflagellates, there would be no accumulation and no problem of algal blooms.
Answer:
PS:Can I be brainliest.
Have a nice day
Explanation:
Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged.
C. Africa
Africa’s projected population graph has the greatest distance between its beginning and ending height on the graph out of all the continents.
The organism that Michelle is studying can best be classified into the domain EUKARYA.
The three domain classification system was introduce by a scientist named Carl Woese. The classification system categorizes all living organisms into three basic domains, which are: archaea, bacteria and eukarya. The archaea and the bacteria groups represent the prokaryotes while the eurkarya group represent the eukaryotes. Eukaryotic organisms are divided into plants and animals. The eukaryotic plants, even though they are multi cellular like animals have some features, which distinguish them from the animals, these include: ability to produce their own food and inability to move around their environment.
Because of the property of paleomagnetism, iron rich rocks show the location of magnetic poles at the time of their formation.
Paleomagnetism is concerned with the study of materials that have a record of the earth's magnetic field due to the content of magnetizable material within them. As iron is easily magnetized, materials with a high iron content are likely to indicate the nature of the magnetic field of the earth when they are formed.
