An antigen is any substance that triggers an immune response. This can include foreign macromolecules, or even harmless substances that the body identifies as foreign. Unnecessary immune responses to harmless antigens can lead to allergies or autoimmune diseases.
Any substance that triggers an immune response is known as an antigen. Antigens are usually foreign macromolecules that are recognized by the cells of the immune system. However, an individual's immune system may also identify harmless substances as antigens, leading to an immune response, such as in the case of allergies or autoimmunity.
In the case of allergies, an individual's immune system reacts to a harmless protein or substance, like pollen, thereby causing symptoms like sneezing or itchy, watery eyes. This is due to an overactive immune response, known as a hypersensitivity response, resulting in the synthesis of IgE antibodies that mediate the allergic reaction.
Autoimmune responses, on the other hand, occur when an individual's immune system mistakenly attacks the body's own cells, causing diseases like rheumatoid arthritis or systemic lupus erythematosus. These arise from a breakdown in tolerance, a process that usually suppresses immune responses to harmless macromolecules.

The difference between yearly and monthly budget is d. There is more uncertainty as you plan further ahead, so a yearly budget needs more room to account for unplanned expenses than a monthly budget does.
Budgets refer to detailed financial plans that outline an individual's or organization's income and expenses over a specific period, typically monthly or yearly. A budget serves as a roadmap for managing finances, helping to allocate funds to various categories such as housing, utilities, transportation, groceries, savings, entertainment, and more.
A yearly budget covers a longer time frame, making it more challenging to predict expenses accurately. Unplanned events, emergencies, or changes in financial situations can occur over a year, leading to greater uncertainty. Thus, a yearly budget should include more flexibility to accommodate unexpected costs and changes while a monthly budget can be more focused on short-term, known expenses.
