Answer/Explanation:
The difference between chromosomes and chromatids
During mitosis, the cell replicates its DNA and passes it onto two daughter cells.
After DNA replication, a chromosome is made up of two identical sister chromatids. When these are separated, they are divided into the two daughter cells so that each contains the genetic material.
When the chromatids are joined together in replicated DNA, they are called chromatids and form the chromosome. When they are divided and separated into two daughter cells, the sister chromatids are called chromosomes again.
Body goes through mitosis
The cells in your body go through mitosis when you need to grow. They divide to form new cells to increase the size of tissues. Mitosis also replaces damaged cells to repair tissues.

Answer:
Emphysema is the gradual destruction of the alveoli, while asthma is a sensitivity to irritants that causes the airway to constrict.
Explanation:
Both "emphysema" and "asthma" are conditions of the lungs. However, they differ in many things.
<em>Emphysema is the gradual destruction of the alveoli</em> caused by an<em> exposure to irritants in the air for a long period of time.</em> This condition starts with a <u>shortness of breath.</u> People may not know they have an emphysema until later in life.
Asthma is the constriction of the airways due to<em> irritants</em> and <em>allergens</em>. Allergens may include<em> pollen, pet dander, dust mites, cold air, etc. </em>A person with asthma has a<em> wheezing sound</em> in the lungs. This is more common in children.
