The respiratory disorder characterized by enlarged alveoli and pulmonary fibrosis is known as Emphysema.

Emphysema is a chronic lung condition that falls under the broader category of chronic obstructive pulmonary disease (COPD). It is primarily caused by long-term exposure to irritants, particularly cigarette smoke. Other risk factors include exposure to occupational dust and chemicals, air pollution, and genetic factors.

In emphysema, the walls of the alveoli, which are tiny air sacs in the lungs responsible for oxygen and carbon dioxide exchange, become damaged. This damage leads to the enlargement of the alveoli and the destruction of their inner walls. As a result, the surface area available for gas exchange is reduced, leading to impaired respiratory function.

Pulmonary fibrosis is another characteristic feature of emphysema. Fibrosis refers to the formation of excessive scar tissue in the lungs. In emphysema, the constant inflammation and tissue damage caused by irritants lead to the development of fibrosis. The scar tissue further contributes to the impairment of lung function by reducing the elasticity of the lungs and limiting their ability to expand and contract efficiently during breathing.

The combination of enlarged alveoli and pulmonary fibrosis in emphysema results in a progressive loss of lung function, leading to symptoms such as shortness of breath, coughing, wheezing, and fatigue. These symptoms typically worsen over time, and severe cases of emphysema can significantly impact a person's quality of life.

Early diagnosis and management of emphysema are crucial to slow down its progression and alleviate symptoms. Treatment approaches may include lifestyle changes, such as quitting smoking and avoiding exposure to irritants, as well as medications to relieve symptoms and improve lung function. In severe cases, surgical interventions like lung volume reduction surgery or lung transplantation may be considered.

In conclusion, emphysema is the respiratory disorder characterized by enlarged alveoli and pulmonary fibrosis. It is a chronic lung condition primarily caused by long-term exposure to irritants, leading to the destruction of alveolar walls, enlargement of alveoli, and the development of pulmonary fibrosis. Early diagnosis and appropriate management strategies are essential for individuals with emphysema to optimize their respiratory function and enhance their quality of life.

Atherosclerosis is a disorder that results from the inflammation, rupture, or erosion of atheromatous plaque in the coronary arteries due to presence of some heavy blockage materials that increase gradually.

As we know, Coronary arteries are the path that supply blood to the heart muscle. However, due to high cholesterol and high blood pressure, the inner wall of Coronary arteries becomes harder and blocks the passage of blood to the heart, which gradually causes the erosion of cell wall and tissue called as atheromatous plaque.

Therefore, the erosion will hurt the person, and the person will have internal burning or inflammation sensations. Thus, the eroded materials will collect in one place and block the passage of blood completely, and the person may die.

During meiosis, the diploid parent cell splits into four haploid daughter cells. The nondisjunction occurrence may result in the failure of homologous chromosomes or sister chromatids to split correctly. One daughter cell may receive two copies of a chromosome, while the other may receive none.

Nondisjunction occurs when chromosomes do not separate correctly during cell division. This may result in the daughter cells having an unusual number of chromosomes. In a cell undergoing meiosis that undergoes nondisjunction, daughter cells receive a different number of chromosomes. Nondisjunction can result in an abnormal number of sex chromosomes or autosomes. In humans, it may cause disorders like Down syndrome.

In normal diploid cells, there are 36 chromosomes. When the diploid cell goes through meiosis and undergoes one nondisjunction event, the daughter cells will receive an incorrect number of chromosomes. The nondisjunction event can cause the daughter cell to receive an extra chromosome or lose a chromosome.

In the given case, a daughter cell undergoing meiosis experiences one nondisjunction event. It means that there would be an error in chromosome separation. If the diploid cell has 36 chromosomes, then the daughter cell after nondisjunction would have an unusual number of chromosomes. Hence, we can't say how many chromosomes are present in this daughter cell.

The false statement regarding gymnosperms is that they produce two types of spores.

Gymnosperms are a group of plants that include conifers, cycads, and ginkgoes. They have several distinct characteristics. One of these characteristics is that they produce seeds, which is true according to option d.

However, gymnosperms do not produce two types of spores. This is a characteristic of ferns and other related plants, known as pteridophytes. Gymnosperms, on the other hand, produce only one type of spore, which develops into a gametophyte.

In gymnosperms, the male gametophyte produces pollen, which is transferred to the female cone or flower for fertilization. The fertilized egg then develops into a seed, which protects and nourishes the embryo. This is an adaptation that allows gymnosperms to reproduce successfully in a wide range of environments, including dry and cold areas.

In summary, gymnosperms do not produce two types of spores. They produce seeds and have a single type of spore that develops into a gametophyte.
