"PRODUCERS" are always found at the base of a food chain.
Oil and natural gas were created by the squeezing of Plankton over millions of years. Oil & Gas were formed (over millions of years) from organic matter like plankton, plants and other life forms. Over time, sand, sediment and rock buried the organic matter and it eventually formed large quantities of fuels.
Answer:
E. By presence of paired homologous chromosomes in the meiotic cell.
Explanation:
Differences between Mitotic Prophase and Prophase 1 of Meiosis:
- The prophase of mitosis is relatively shorter than prophase 1 of meiosis.
- Prophase of mitosis is characterized by the disintegration of the nuclear membrane and the movement of the duplicated centrioles towards the two poles of the cell.
- Prophase 1 of meiosis is relatively longer and involves a number of consecutive events that do not occur in the mitotic prophase.
- Prophase 1 of meiosis involves the disintegration of the nuclear membrane as well. But the most important event of this phase is the pairing of homologous chromosomes through a connection called a synapse. This is called chiasmata formation. Homologous chromosomes pair up in form of tetrads and exchange segments with each other. This process is called crossing over and it is crucial in the production of genetically varied daughter cells.
(D). Evolution is a process where the individuals with the strongest traits for survival in there given environment are able to reproduce more effectively and those traits are inherited by offspring. This is constantly happening to species at different rates based on environmental pressures.
