All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.
In crossing over, the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined...
- independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations- there are two possibilities of arrangement for the chromosome pair at the metaphase plate
- the principle of independent assortment determines that multiple (more than 2) individual characteristics assort independently and two distinct traits may have equal chances of occuring together
- the chromosome pairs form haploid cells which are randomized arrangements of homologous chromosomes.

Incomplete question. The remaining part of the question read;
Put the processes in order to describe the interaction between these two systems.
- Then Blood is pumped through the circulatory system to deliver nutrients to other organs.
- Digestive processes break nutrients down in the mouth, stomach, and small intestine.
- Nutrients are ingested at the mouth. Nutrients enter the capillaries of the circulatory system.
- Nutrients diffuse through the villi of the small intestine.
<u>Explanation:</u>
<u><em>The correct order of processes:</em></u>
- Nutrients are ingested at the mouth.
- Digestive processes break nutrients down in the mouth, stomach, and small intestine.
- Nutrients diffuse through the villi of the small intestine.
- Nutrients enter the capillaries of the circulatory system.
- Then, Blood is pumped through the circulatory system to deliver nutrients to other organs.
So, the first sequence begins when nutrients from the food we eat enter the mouth. Our digestive system begins to work as we chew the food using our teeth. When the food is swallowed into the stomach the digestive process continues until nutrients contained in the food are then diffused or absorbed by the Villi; a part of our small intestine, to be used by other body organs. Then, Blood is pumped through the circulatory system to deliver nutrients to other organs.
