Chronic obstructive pulmonary disease (COPD) is the world's top cause of death for the greatest number of individuals, known for its chronic obstructive diseases, chronic bronchitis, and emphysema.
<h3>How genes impact on COPD?</h3>
- The precise causal process of COPD is still unknown, despite several attempts to discover biomarkers and pathways.
- In order to better understand the biological mechanism and network module underlying COPD, this study integrates information on biological interactions with information on gene expression.
- 49 genes were chosen using a sparse network-based technique from the peripheral blood mononuclear cell expression data of 136 participants, comprising 42 ex-smokers and 94 COPD patients.
- The findings indicate that these 49 genes may have an impact on COPD-related biological functions and molecular processes.

Answer:
The answer is option a.progesterone, c.estrogen and option d. human chorionic gonadotropin.
Explanation:
These hormones serve various functions.
I. Human chorionic gonadotropin: this signals the mother that pregnancy has occurred by maintaining the production of progesterone from the corpus luteum. This is what is detected during a pregnancy test.
ii. Progesterone maintains the pregnancy by supporting the lining of the uterus.
iii. estrogen stimulates the growth of the womb to accommodate the growing fetish.
B. I, II, III
