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.
Answer:D. tapeworms live inside a goats body in a close relationship the goat.
Explanation:
In parasitic relationships,the parasite lives on the host and benefits from the host while causing harm to the host .the host does not benefit.the parasites are usually in close relationship with their host as their food source are substances of the host organisms.
The parasite may live in the host , these are called Endo-parasites.
The parasite may live outside the host, these are called ecto-parasite. In this example, the tapeworm is an endo-parasite that lives in the digestive tract of the goat. It absorbs digested food in the intestine through it's body surface.
In predator and prey relationship, the predator usually has to hunt for the prey and feed on it. It may kill it first or may not
