DNA is an acid that contains resources needed for development and function of every living thing, EVERY LIVING THING. even bacteria and viruses have DNA. without DNA there would be no life.
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.
A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
Answer:
its 9 for the first one
Explanation:
look at the other ones they all contain a pattern of having half the amount
Prokaryotes do not have a nucleus, are smaller, and reproduce quickly
eukaryotespecially have a nucleus and are larger/more complex
