Humans use their respiratory system to inhale oxygen and exhale carbon dioxide. It also allows people to talk, laugh, and sing.

Major organs involved include the nose and mouth, nasal passages, trachea, bronchi (singular: bronchus), lungs, alveoli, and diaphragm.

The respiratory system has a close relationship with the circulatory system, oxygenating blood for tissues to survive and expelling carbon dioxide as waste.

Which of the following did you include in your response? Check all of the boxes that apply. Women have two X chromosomes. Recess
Bond [772]

All of the statements are true.

The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.

Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.

In this mode of inheritance, the morbid allele behaves like a recessive trait.

Women heterozygotes are not affected but can transmit the disease; they are said to be conductive of the disease.

The disease is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)
