Answer:
The statement '<em>the genetic material of the original cell is divided among the new cells</em>' describes how cells are produced in meiosis process.
<u>Explanation: </u>
<em>In meiosis a single cell is divided into twice to form four cells and it contains the original half amount of 'genetic information'.</em> In meiosis, the two cells are called daughter cells are produced, and each identical cells to the parent cell meiosis are produced four haploid cells and mitosis are produced two diploid cells.
<em>The meiosis cell division is to reduces the number of 'chromosomes' in the parent cell by its half portion and also they produce four gamete cells.</em> In this process they required to produce 'eggs and sperm' cells for the sexual reproduction .It is the main aim to make a daughter cells with same half so many 'chromosomes' as the starting cell.
Answer:
Phenotypic changes:
When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.
It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.
Evolutionary processes:
It's natural selection that allows the fittest organism to survive. As in the case of the mutants
Answer:
B. . The process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be
used for cell functions.
Yes, Only bacteria can convert molecular nitrogen, into a form which can be utilized by other living beings such as plants. The nitrogen fixed by the bacteria, by this process, become available to the plants, which uptakes it, for their own growth, and is also accumulated in their seeds. Further, leguminous plants have nitrogen-fixing bacteria associated with them in synergy. They provide the plant with additional nitrogen, and in exchange obtain nutrients from the plant, for their growth and division.
