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:
Plants use sunlight to convert CO2 and H20 to Glucose and Oxygen
Explanation:
Photosynthesis is the process in which Plants absorb sunlight via the pigment chlorophyll to convert CO2 and Water to Glucose and Oxygen
The molten material moving in the mantle due to circulation moves the lithospheric plates
The principle is that adenine is always paired to thymine; and cytosine is always paired to guanine. In this particular sequence:
<span>3'-cgcatgtagcga-5'
The complementary leading strand will be:
5'-GCGTACATCGCT-3'</span>
Answer:
ATP molecules
Explanation:
Density centrifugation is a method that separates components of a sample on the basis of their density or density gradient.
During centrifugation the sample will be layered according to their density and that is the principle of density centrifugation.
When centrifuging a sample containing homogenized cells. ATP molecules will be found at the top of the centrifugation gradient due to having a lighter density compared to the rest of the molecules.
