Answer:
The essential factor to increase the number of cells in a growing organism is that each and every cell has a complete copy of DNA.
Explanation:
The development and growth of an organism is based on the multiplication of its tissue cells. Cell multiplication in somatic cells occurs through mitosis, a process that allows obtaining<u> two identical daughter cells from a progenitor cell</u>.
DNA contains all the genetic information belonging to a living organism. In the process of mitosis, the DNA of each cell must be replicated so that each daughter cell has a complete copy of the original DNA. This ensures that each cell resulting from mitosis has the same structure and function as the original cell.
The other options are not correct because:
- <em>The </em><u><em>size of the cell is important</em></u><em>, since each cell has defined characteristics, according to the tissue it must form.
</em>
- <u><em>Each and every cell needs to have a complete DNA</em></u><em>.
</em>
- <em>In somatic cells, </em><u><em>DNA does not vary from one cell to another</em></u><em>.</em>
Answer:
The correct answer is - Altimeter.
Explanation:
An altimeter is a sensor that is present in the new Fitbit. Altimeter measures changes in air pressure or barometric pressure. This sensor is used to count floors and use each 10 feet elevation as one floor.
Altimeter shows reading by the pressure of the air and every time the air pressure increases altitude is decreases and if air pressure decreases there is an elevation in altitude from sea level.
D. ATP (Adenosine TRIphosphate) has one more phosphate group and is higher in energy than ADP (Adenosine DIphosphate). TRI means three, DI means two, so the names of the molecules tell you there's one more phosphate in ATP than in ADP.
That extra phosphate makes ATP higher in energy (when the cell uses that energy to do something - contract a muscle fiber, for instance - the ATP's extra energy is used and it gets converted to ADP).
Answer:
Cretaceous
Explanation:
From what has been examined so far, there are evidence that at the end of the Cretaceous period a very large asteroid or comet stuck the Earth. The impact was where modern day Yucatan is located, and it released such an enormous energy that it managed to change the face of the Earth. The explosion itself managed to kill off pretty much everything nearby, but there was also a very hot wave that circled the whole planet. Enormous amounts of dust and ashes were released into the atmosphere that blocked the Sun, and the volcanoes all over the globe were triggered. This caused major climate and environmental changes, leading to a mass extinction, with the most noticeable victims being the dinosaurs.
