Meiotic nondisjunction could be a result of . See Section 13.3 (Page) . Steps of meiosis: 1. Interphase (Before meiosis begins): Uncondensed chromosomes replicate in parent cell. Meiosis I (homologous chromosomes separate): 2. Early prophase I: Chromosomes condense, spindle apparatus forms. Pairing of homologous chromosomes. 3. Late prophase I: Chiasmata (crossover points) visible. 4. Metaphase I: Movement of bivalents to metaphase plate is complete. 5. Anaphase I: Homologs separate and begin moving to opposite poles of the spindle apparatus. 6. Telophase I (Before Meiosis II begins): Homologs finish moving to opposite poles. Cytokinesis: Cell divides; chromosome number is reduced. Meiosis II (sister chromatids separate): 7. Prophase II: Spindle apparatus reforms. 8. Metaphase II: Chromosomes are lined up at metaphase plate. 9. Anaphase II: Sister chromatids separate, begin moving to opposite poles. 10. Telophase II: Daughter chromosomes finish moving to opposite poles. Cytokinesis: Cell divides; chromosome number is unchanged.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

explanation:

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
