The most appropriate unit for describing a 26 mile marathon run would be C. Kilometre. As kilometres can be easily utilized and converted to miles and vice-versa.
Answer:
Explanation:
The final component, or bottom plate, takes the form of an electrically grounded roll. In the corona treating system, the voltage buildup ionizes the air in the air gap, creating a corona, which will increase the surface .
Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the
phase,</em> - <em>the
phase,</em> - <em>the S phase; and</em>
- <em>the
phase</em>.
The phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of phase.
The correct option is b.
Answer:
Seismic waves, Outer, Mantle
Explanation:
P-waves vibrate longitudinally to the direction of propagation while S-waves vibrate vertically to direction of propagation. This is why S-waves are called shear waves while P-waves are compressional waves. S-waves are the main cause of destruction in an earthquake and are slower than P-waves.
The wave movement of P-waves allows them to pass through liquids and gases while S-waves cannot. Due to this differential phenomenon of these waves, the reflection of P –waves and S-waves after an earthquake – and as their vibrations are picked up by seismographs around the earth - enabled scientists to determine the properties of the layers of the earth’’s interior.
Answer:
Chloroplasts are what give plants their green color. The second major difference between plant and animal cells is the cell wall. While both plant and animal cells have a cell membrane, on plants have a cell wall.
