Ans.

Cell cycle includes a series of events, which leads to DNA duplication, followed by formation of new cells from a parent cell. In humans and other higher organisms, cell cycle consists of four phases, G1 (gap 1), S phase (synthesis phase), G2 phase and M phase (either mitotic or meiotic phase), in which mistakes can occur.

During G1 phase, cell prepares itself to divide and makes proteins, required for DNA synthesis during S phase. Errors occur when cell cannot make sufficient proteins and other necessary raw materials.

During S phase, DNA replication takes place to gets divided into daughter cells. Errors during S phase includes mutations and loss of DNA integrity.

During G2 phase, cell gets prepared for mitotic or meiotic division. Errors that occurred during S phase are repaired during G2 phase. Mistakes in repairing those errors result in problems as they will pass to the new daughter cells through M phase.  

During M phase, separation of duplicated chromosomes into daughter cells occurs. Mistakes that can lead to errors during this phase include chromosomal abnormalities, such as polyploidy or enuploidy.

A gardener is installing several large flower beds. The flower beds will vary in length from 5 to 12 feet. Depending on the type
dezoksy [38]

The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.

<h3>How to calculate amount of landscaping plants?</h3>

 just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.

<h3>How to calculate the spacing between plants?</h3>

If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).

With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
