Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only one variable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

Answer: It is easier to prevent the degradation of old soil than it is to generate new soil.
The initial cell division of meiosis , known as meiosis I, divides the chromosomes into two cells. After this division, each cell receives a ploidy number of 2N.
<h3>What is the meiotic ploidy?</h3>
After meiosis II, there is no decrease in ploidy since both parent and daughter cells only have one copy of each meiosis. Each cell after mitosis has a chromatid for every homologous chromosome. Thus, each cell has enough DNA to make two copies of each chromosome.
Reductional division also occurs during the first meiotic stage, when a diploid parent cell divides into haploid daughter cells, resulting in a shift in ploidy. Meiosis II does not include a change in ploidy because it is an equational division.
