Below given are the answers :-

1. Lungs can be compared to balloons and the bronchioles as Y- tube. When the air is blown through the Y-tube, the balloons expands. This shows that the lungs (balloons) expand during inhalation.

2. Lungs can be featured as the " heart " of a living body. Uses of lungs are innumerable.

• Lungs help in respiration.

• Lungs help in increasing oxygen content in our body, which is necessary for our existence.

3. Answer is NO. It is not possible to work if only one lung is functioning. Both lungs play a minor difference role in the body.

1.

The device used to compare to the human lungs is " balloon ". It works once it is filled with air, can be oxygen or helium it would expand just as how diaphragm works in human lungs. And while removing the amount of air, it's the same process that goes along with the human lungs.

2.

Description about the feature of the lungs : -

The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel - lined sacks in which oxygen and carbon dioxide gas are exchanged.

3.

Yes, it would be possible to work if only one lung is functioning.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
