40 POINTS!!!!!!The diagram above shows some of the components of the lymphatic system. The lymph node contains a large collection of cells, labeled A, through which the lymph flows. What is the function of this cluster of cells?
A. To remove pathogens from the lymph
B. To recover protein from the lymph
C. To pump the lymph through the lymph node
D. To transport oxygen to other lymph node cells
Answers
To remove pathogens from the lymph node is the function of cells labelled A.
What is Lymph node?
- A little bean-shaped structure that is part of the immunological system of the human body.
- Lymph nodes contain lymphocytes (white blood cells) that assist the body fight infection and sickness by filtering things that move through the lymphatic fluid.
- Hundreds of lymph nodes can be located all over the body.
- Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin.
- They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.
Hence the correct option is A.

The Correct Answer to this Question would MOST LIKELY be "To remove pathogens from the lymph" since Lymph is a liquid produced by the body full of white blood cells, the lymph node's job is to filter pathogens and impurities from the white blood cells.
In Other words, The only Option that seems Correct would be "A"
Hope this Helps at Least! :)

Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.
Final answer:
The substance produced by a chemical reaction in carbohydrates is energy. This reaction, known as metabolism, involves the breakdown of glucose into energy (adenosine triphosphate or ATP) and waste product (carbon dioxide). Carbohydrates are complex molecules comprised of carbon, hydrogen, and oxygen, and exist in forms that vary based on sugar unit quantity.
Explanation:
The substance produced by a chemical reaction in carbohydrates, specifically glucose (a simple carbohydrate), through a process called metabolism, is primarily energy. Glucose, with the chemical formula C6H12O6, is an essential source of energy for most living organisms. During cellular respiration, energy is released from glucose, and that energy is used to produce adenosine triphosphate (ATP), a compound critical for energy transfer within cells.
Another product of carbohydrates metabolism is carbon dioxide (CO2). This reaction can be represented as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy. With energy being utilised by the organism and carbon dioxide generally being expelled as a waste product.
It's important to note that carbohydrates are large biomolecules composed of carbon, hydrogen, and oxygen, and come in different forms — monosaccharides, disaccharides, oligosaccharides, and polysaccharides — which are classified based on the number of sugar units they contain.

Final answer:
The most serious health risk of anorexia nervosa is death. Anorexia nervosa is an eating disorder which causes extreme weight loss and can lead to serious health complications such as heart conditions, kidney failure, and electrolyte imbalance which can potentially cause death.
Explanation:
Among the given choices, the most serious health risk from anorexia nervosa is death. Anorexia nervosa is a psychological and potentially life-threatening eating disorder which causes people to obsess about weight and what they eat. It's characterized by a self-imposed starvation resulting in extreme weight loss. Additionally, anorexia causes such serious health problems like heart conditions, kidney failure and electrolyte imbalance which can ultimately lead to death. Therefore, while weight loss, low body temperature, and growth of fine body hair are all symptoms and consequences of anorexia nervosa, death is the most serious risk.
