Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
Answer:
1. metaphase I
2. telophase II
3. anaphase I
4.prophase II
5. prophase I
6. anaphase II
7. telophase I
8. metaphase II
Explanation:
1. During _metaphase I________, pairs of homologous chromosomes align in the center of the cell.2. During _telophase II___, the separated chromatids elongate and (usually) cytokinesis occurs, formingfour genetically distinct haploid daughter cells.3. During _anaphase I_______, homologous chromosomes separate by moving with the spindle microtubulestoward the poles.4. During __prophase II______, a spindle apparatus forms and individual chromosomes (each composed ofsister chromatids) begin to move toward the center of the cell.5. During _prophase I_______, chiasmata form and crossing-over occurs.6. During _anaphase II_______, sister chromatids separate and move toward the poles.7. During __telophase I______, the separated chromosomes cluster at the poles of the spindle and cytokinesis occurs, forming two daughter cells, each with a haploid set of replicated chromosomes.8. During ___metaphase II_____, individual chromosomes (each composed of sister chromatids) align in the center of the cell.
The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.
