Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.
Answer:
Fungi and bacteria help other things such as wast and minerals break down and reproduce. They are very important role of organisms. Without them our grounds would be full of trash and non broken down minerals. Our lands would be toxic on the outside, and many animals would die. It isn't on the food chain because, nothing really eats it, because some are toxic, but we also need them for the environment and breaking down things.

<h3>Hi!</h3>
The correct answer is D. Decrease in soil fertility.
<h3>Explanation:</h3>
A particular crop has a particular need for certain nutrients, and contributes a certain set of nutrients in return to the soil. When the same crop is planted over and over the years, the certain set of nutrients required to sustain are used up, and an accumulation of particular nutrients not essential for that particular plant's growth piles up. This leads to poor growth and development of the plant due to nutrient deficiency - and the quality of a soil to sustain growth and agriculture of a plant is known as fertility, which in this case decreases.
