Asthma is a chronic disease of the lung that has been increasing at an alarming rate in industrialized countries around the world over the last few decades. Although considerable progress has been made in our understanding of the underlying pathogenesis of the disease, the exact causes of the increasing prevalence are unknown. Studies suggest that most asthma develops in early childhood and that environmental factors present early in life may be crucial in the development of disease. One potential explanation for the recent epidemic referred to as the "hygiene hypothesis" postulates that factors that have resulted in a reduction in exposure to microbial products and/or infections in the western world may be contributing to this rise in disease prevalence. As early life influences are known to play an important role in establishment of asthma, studies have focused on the interface between mother and child that occurs during gestation and through breastfeeding. In this regard, the body of evidence regarding the relationship between breastfeeding and asthma indicates benefit but with the potential for risk. While providing population-level protection from infections and atopy in infancy and early childhood, breastfeeding might also pose an increased risk of atopic asthma among children with asthmatic mothers.
B. Because it is a dominant trait
The options attached to the question above are given below:
A. The balance of ions inside a cell will be disrupted and proteins could leak out because the phospholipid bilayer forms the cell membrane.
B. Energy storage will be disrupted because the phospholipid bilayer is responsible for storing energy in the body.
C. Chemical messages could not be sent to different parts of the body because the phospholipid bilayer forms hormones.
D. A person would be vulnerable to disease because the phospholipid bilayer helps to fight infections in the body.
ANSWER
The correct option is A.
The phospholipid bilayer is found in all cell membranes. It functions by providing a critical barrier which signifies the boundary of cells and allow only specific particles to pass into the cells. Damage to the phospholipid bilayer result in disturbance of the ions that are inside the cells, the proteins and other components of the cell could also leak out. Beside these, particles, that are normally prevented from entering into the cells can easily gain entrance into the cells.
Distribution of sunlight. Why is an organism's niche like a person's occupation? An organism can "make a living" and survive in its niche. a natural phenomenon that maintains Earth's temperature range.
