Without using the scientific method, it would be much harder to determine a factor that could cause your experiment to fail. By sticking to only one of the methods you could easily destroy your experiment without the background search needed or the materials planned out.
Answer: White blood cells form to fight off cell infections.
Explanation:
1. Your body produces white blood cells which fight against infected cells, depends on what type of cell it is and how infected it is.
2. The immune response to a viral infection is primarily generated by a type of white blood cell called lymphocytes; cells that are mostly localized in ‘lymphoid tissues’ such as the lymph nodes or tonsils. However, the number of lymphocytes that can recognize and react against any individual type of virus is initially very small. This is particularly true for a novel virus such as SARS-CoV-2, which people have never encountered before. In order to produce an effective immune response, the small number of lymphocytes that can recognize a virus must become more abundant. Even though lymphocytes proliferate quickly it still takes several days before there are sufficient cells available to fight back against the infection. During this period the virus may also be spreading rapidly, so there is a race between the virus and the immune system that may determine the final outcome, in terms of recovery.
Answer:
Coombs reagent is an antiserum with antibodies that bind to the human <u>antibodies attached on the surface of the erythrocytes.</u>
Explanation:
Coombs test is a blood test used in immunology and immunohematology. It is of two types: direct and indirect.
The Coombs reagent is an antiserum, containing antibodies.
The direct Coombs test detects the antibodies present on the surface of the erythrocytes.
In this test, when the Coombs reagent is reacted with the blood to be tested, <u>the antibodies in the Coombs reagent binds to the antibodies attached on the surface of the erythrocytes in the test blood and cause agglutination.</u>

Xylem is a specialized tissue in vascular plants that is primarily responsible for the distribution of water and nutrients from roots to stems and leaves. The xylem also provides mechanical support and storage to the plant.
Phloem is a specialized tissue in vascular plants that is primarily responsible for the distribution of food nutrients such as glucose (sugar) and amino acids from the leaves to various parts of the plant
