Answer:
Cell copies its genetic material during the S-phase of the interphase during cell cycle.
Explanation:
- Cell cycle is broadly divided into two phases ; the interphase and the M-phase.
- M-phase is the dividing phase during which the karyokinesis and cytokinesis takes place.
- Interphase is the phase during which the cell prepares itself for division.
- It is further divided into G1, S and G2 phase.
- During G1 phase the cell prepares for DNA replication and the replication complexes assemble.
- The next phase is S-phase during which the DNA replicates itself and the genetic material in the cell doubles.
- The Next phase is G2 phase during which the DNA is scanned by DNA tepair complexes and errors in the replicated DNA are edited and repaired.
- At the end of G2 phase the cell prepares to enter M-phase.
Answer:
4 meters a second
Explanation:
25 * 4 = 100 or vice versa 100 / 25 = 4
Answer: mode of reproduction
Explanation: Phylum pteridophyte are vascular plants this means they are plants that possess xylem and phloem tissues. Phylum pteridophyte reproduce and disperse by spores. The dominant phase in pteridophyte is sporophyte.
Phylum bryophyte lack true roots and they are non-vascular plants (no xylem and phloem tissues). They reproduce via gamates, the dominant reproductive phase in bryophyte is gametophyte.
Answer:
false
Explanation:
We know how the water cycle should work, but nature can not be predicted. The water cycle is changed daily based on droughts or flooding
