Answer:
Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well.

If a scientist is monitoring cytokinesis in a cell, then the scientist must be witnessing Anaphase
<h3>What
is cytokinesis ?</h3>
In biology, cytokinesis is the process through which a single cell physically divides into two. Cytokinesis, which occurs throughout embryonic development as well as tissue growth and repair in higher plants and animals, is the primary reproductive activity of unicellular organisms.
- Cytokinesis serves the following purposes The process aids in preserving the precision of cell division. where the descendant cells' cytoplasmic component is distributed uniformly. The method aids in giving the division more accuracy.

I would say B. mitosis because that is the process of building cells. Meiosis is also the process of building cells but only applies for sex cells.
Hope this helps(;
Answer:
Ultimately what makes each cell different despite the fact that they share the same set of DNA is regulation of gene expression, which regulates the expression of genes. In other words, it determines which genes are turned off and which are turned on in a cell. Gene expression can be regulated in many ways; it's mainly centered around molecules like transcription factors that have the ability to turn certain genes on and off and activators, which promote transcription of DNA.
The short answer to this question is cell differentiation. Differential gene expression results from the genes being regulated differently in each cell type, and differential gene expression leads to different cells.
In fact, from the very beginning of our lives, so to speak, when we're developing from a zygote into an embryo, the egg that makes up the zygote in fact already has a sequential program of gene regulation tat is carried out as cells divide, and this program makes the cell become different from each other in a coordinated fashion.
