Answer 1

nodes

Viruses

fungi

histamine

B-cells

antigens

Fever

When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.

Answer 2

The question in incomplete and blanks are not clear in the question, so the complete question is as follows:

1. Lymph ______ are found throughout the body and are a signal of a disease, infection, or problem if they become and remain swollen for long periods of time.

2. ______ are pathogens that cannot be killed with antibiotics because they are non-living. They take over cellular organelles to replicate and spread.

3. Because they are also eukaryotes with their own cell membranes and membrane-bound organelles, ______ are often difficult to combat with medicines.

4. A cell signal called ______ is produced by mast cells. These molecules cause more fluid to spread to an infected area. _______ are the types of cells that produce antibodies.

5. All pathogens have unique identifying molecules on their surfaces called ______. Antibodies bind to these, and targeting the pathogen to be destroyed by the immune system.

6. ______ is a non-specific response to disease, in which the body temperature rises.

Answers:

1. Nodes

2. Virus

3. Viruses

4. Heparin, B Lymphocytes

5. Antigens

6. Fever

Step-by-step explanation:

1. Lymph nodes are lumps of tissues that consist of white blood cells and help to fight against infection-causing viruses and bacteria. Swollen lymph nodes are signal of several diseases such as cancer and HIV.

2. The Virus is the pathogens which are not killed by antibiotics because virus are present in non-living form and are activated only when coming in contact with a living body. That is why Virus depends on cellular organelles for its replication and spread over the living body.

3. Viruses have similar characteristics as eukaryotes such as cell membrane, RNA or DNA, a protein capsule, and membrane-bound organelles and are not able to combat with medicines and vaccines are used to prevent viral diseases.

4. Heparin is a signal released by mast cell. These molecules prevents clotting of blood and allow blood to flow to the area of infection or injury. B lymphocytes or B cells are specialized white blood cells that produce antibodies.

5. All pathogens have a different molecules at their surface called antigen. Antibodies present in body or introduced clinically bind with these antigens and kill or stop the growth of bacteria or pathogen.

6. Fever is one of the non-specific immune response in which body temperature rises with the invasion of pathogens.

Hence, the correct answers are:

1. Nodes

2. Virus

3. Viruses

4. Heparin, B Lymphocytes

5. Antigens

6. Fever
