What is the clonal selection theory as it applies to B cells?
The clonal selection theory explains how B cells produce antibodies in response to specific antigens. When a B cell encounters its specific antigen, it proliferates and differentiates into plasma cells that secrete antibodies. This theory underlies the adaptive immune response and the specificity of antibody production by B cells.
Can packed cells and fresh frozen plasma be transfused at the same time?
Yes, packed red blood cells and fresh frozen plasma can be transfused at the same time to a patient, especially in situations where both red cell support and plasma volume expansion are needed. It is important to follow specific protocols and guidelines for compatibility testing and administration.
What are long lived b cell clone members that do not become plasma cells but are capable of an immune response against the same antigen at a later time called?
Memory Cells
List the fluid compartments that could be defined as extracellular?
The extracellular fluid compartments include the interstitial fluid (found between cells) and the intravascular fluid (found within blood vessels).
What is the difference between cristae and mesosome?
Cristae are internal folds of the inner mitochondrial membrane that increase surface area for cellular respiration. Mesosomes are invaginations of the plasma membrane in prokaryotic cells that are involved in cellular processes like cell division and respiration. Mesosomes are not found in eukaryotic cells.
Is plasma and blood the same thing?
yes!!!!!!!!!!!!!!!!!!!!!!!!!! at least i think so
Where is the plasma membrane?
Plasma membrane is the same as "cell membrane" it's one of the four characteristics of all cells. So plasma membrane is found "coating" the outside of all cells.
Where is the plasma membrane found?
The cell membrane is the outer boundary of animal cells and plant cells, but plant cells also have a cell wall to protect their cells. The cell membrane and cell walls are the outer boundaries of cells.

Is plasma same as blood?
The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells.
How bad can one feel after plasma donation?
To make a plasma donation is the same as a blood donation. Red blood cells float in plasma, so they take the blood and seperate the plasma. So you might feel a bit dozy or weak after, but this isn't common.
What is acquired Immune Response?
The acquired immune response is also known as the specific immune response. This involves the presentation of micro organisms antigens by macrophages to T and B lymphocytes (T and B cells). T cells and B cells specific to these antigens will then go through clonal expansion (mass production) to help carry out a specific response that has been 'acquired' as a direct result or particular microorganisms antigens. T cells are divided into T helper and T killer, and B cells into memory cells and plasma cells. T helper cells aid B cells in their production and carrying out their functions. T killer cells kill infected cells (those containing viruses or bacteria, as detected by their presentation of antigen on MHC Class 1 receptor molecules on their surface). B cells differentiate into plasma cells and memory cells, plasma cells produce antibodies specific to the type or types of antigens detected. Memory cells have the ability to live for long amounts of time and quickly differentiate into plasma cells should the same antigens present at a later date, allowing a faster and more efficient immune response if infected again with the same microorganism. The acquired immune response usually takes 7-10 days after initial presentation of the antigens by macrophages - unless this is a secondary response, in which case the person should have already produced memory cells so can deal with the invading microorganisms faster and more efficiently. The innate (passive) immune system is responsible for initial responses, this is non specific and involves neutrophils largely.
Do humans have the same cells?
no they dont! they are their own thing! :)
Is plasma and cytoplasm same?
No, plasma and cytoplasm are not the same. Plasma refers to the liquid component of blood that carries blood cells, while cytoplasm is the gel-like substance found inside cells that contains organelles and where many cellular processes occur.
How do animals and plants relate to plant cells and animal cells?
Because they are the same thing
Do elephants and giant trees have big cells?
steven no they have the same cells. same as every thing it goes into each other
