Can packed cells and fresh frozen plasma be transfused at the same time?
yes
What is the clonal selection theory as it applies to B cells?
1. An antigen presenting cell presents antigen on Class II MHC to a Helper T cell activating it 2. At the same time a B cell that has taken up and degraded the same pathogen displays antigen on its class II 3. The activated helper T cell binds to the B cell releasing cytokines and activating it 4. The activated B cell proliferates and differentiates into: 1) memory B cells 2) antibody-secreting plasma cells that produce antibodies specific for the pathogen
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
Are neurons and nerve cells different name for the same thing?
True
How does the plasma membrane of the cell compare with the membrane in the U-shape?
Angiotensin is activated by a renal enzyme called
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.
Can packed cells and fresh frozen plasma be transfused at the same time?
yes
Where is plasma the fourth state of matter found?
plasma is found in stars. the only naturally occurring plasma on Earth is lightning. it is not to be confused with the plasma in your blood however, as these are not the same thing. plasma screen TVs use plasma the same way as fluorescent lights, but this is not naturally occurring plasma.
What correctly identify components that are the same in both plant cells and bacterial cells?
Cytoplasm, DNA, plasma membrane, ribosomes
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.

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! :)
How do animals and plants relate to plant cells and animal cells?
Because they are the same thing
