Lydia was bitten by a fire ant. The bite hurt and itched, but wasn't very bad and cleared up quickly. A few months later, she was bitten by a second fire ant. This time, the bite rapidly swelled, became very red and hot, and she developed itchy patches all over her body. Why were her symptoms so much worse the second time she was bit?

A Lydia was not allergic to the first type of fire ant but she must have been bitten by a different type of fire ant that she was allergic to.

B Lydia was always allergic but the first time the ant was very small.

C When Lydia was bitten the first time, her body created antibodies and memory cells against the venom and the second exposure elicited a stronger reaction.

D When Lydia was bitten the first time she had not yet developed the antibodies in her Thymus.

Answers

Answer 1
The answer is c because the first time she is bitten her body is experiencing it for this first time so the antibodies would be enough for it to go away. The second time will affect her even more since it will give a stronger reaction.
Answer 2
After reading that I think C would be the best choice

Manage oxygenation and ventilation according to protocols for PARDS
Correct hypoxemia with ventilation strategies and PEEP
Consider hypercapnia, as indicated

Answers

Continuous positive airway pressure (CPAP), bi-level airway pressure (BiPAP), proportional-assist breathing, and a high-flow nasal cannula are used to treat this lung tissue condition.

Pulmonary edema is a disorder caused by an accumulation of fluid in the lungs. This fluid accumulates in the lungs' many air sacs, making breathing harder. In most situations, pulmonary edema is caused by cardiac issues. However, fluid can accumulate in the lung for a variety of causes. These include pneumonia, exposure to certain chemicals, drugs, chest wall damage, and going to or exercising in high elevations.

Acute pulmonary edema (acute pulmonary edema) is a medical issue that needed rapid attention. Pulmonary edema is sometimes fatal. Prompt therapy may be beneficial. Treatment for pulmonary edema varies depending on the cause, but usually includes more oxygen and drugs.

What term is defined as the state of balanced health and well being?

Answers

Wellness term is defined as the state of balanced health and well being

The World Health Organization (WHO) defines health as "a full condition of physical, mental, and social well-being, rather than only the absence of sickness or disability." A person in good physical health are likely to have optimal body functions and processes. There are several sorts of well-being, including such mental well-being, physical well-being, economic well-being, and emotional well-being. The many types of well-being are frequently intertwined. Greater physical well-being, for example, is related to improved emotional well-being (e.g., by lowering or quitting an addiction).

Another example is that stronger economic well-being (having more income) is connected with better emotional well-being, even under difficult conditions like the COVID-19 epidemic.

Well-being is important in ethics since what we should do depends, at least in part, on whether it would make someone's life better or worse. There are no additional values except well-being, according to welfarism.

The urinary bladder is a strong muscular organ that stores the urine until it can be excreted via the (__________)

Answers

Answer:

There are air filters to purify the air and water filters to clean the water. Well, the kidneys are like a filtering system, too. They contain nephrons, which filter waste from the blood in two stages. First, nephrons take waste as well as needed materials out of blood. Then, the materials the body needs (like water and glucose) are returned to the blood and wastes are eliminated from the body. This is one way the kidneys maintain homeostasis. The kidneys also regulate the amount of water in the body. The amount of water the kidneys return to the blood depends on the conditions inside and outside of the body. This is another way the excretory system maintains homeostasis. For example, you will make more urine on a cool day when you have drunk a lot of water than you will on a hot day when you've hardly had anything to drink.

How do hormones turn on genes?

Answers

Hormones turn on genes by binding to receptors on the surface of a cell or inside of a cell. This binding activates a signaling pathway that triggers gene expression. This gene expression can cause changes in the cell such as cell growth, differentiation, and metabolism.  

The binding of a hormone to its receptor creates a complex that  then binds to specific DNA regions called hormone response elements. These binding sites act as promoters for genes, allowing for the transcription of the gene. Hormone receptors can also bind to other transcription factors, which can further enhance the transcription of the gene.

This process of hormone binding to receptors and resulting gene expression is tightly regulated by negative feedback loops, which help ensure that hormones are only released when needed and in the correct amounts.
