What is the function of plasmodesmata in plant cells?
The passage between two cells. Water and nutrient passages, generally.
What proteins on surface of cells have carbohydrates attached to protein?
At the heart of the immune response is the ability to distinguish between "self" and "non-self." Every cell in your body carries the same set of distinctive surface proteins that distinguish you as "self." Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers; rather, your immune system coexists peaceably with your other body cells in a state known as self-tolerance. This set of unique markers on human cells is called the major histocompatibility complex (MHC). There are two classes: MHC Class I proteins, which are on all cells, and MHC Class II proteins, which are only on certain specialized cells.
What is the difference between T-cells and killer T-cells?
Cytotoxic T-cells are just a specialized subset of T-cells that express CD8 (a co-stimulatory molecule). In general, there are two types of T-cells, helper T-cells that express CD4 and cytotoxic T-cells that express CD8. As the name implies, cytotoxic T-cells have the role of killing any infected cells.
What happens to cells as organisms grow?
individual cells grows in size, but there are limits to the size that cells can reach. cells need a high ratio of surface area to volume in order to function. as a cell grows, that ratio decreases. when the cell divides into two smaller cells, the ratio of surface area to volume for each cell increases.
Cells are copied using excels copy function what happens yo the data in the copied cells?
the data of copied cells is distributed to the two daughter cells during prophase

Does the sum function compares the contents of two cells?
No. It is for adding up values.
When bacteria is divided into cells is called?
For reproduction, Bacteria undergo the process of binary fission. In this, the cell divides into two identical cells which makes them to function as two different cells from thereon.
Example of sum of 2 no's in predefined function?
You can use the Sum function. You can do it as a range of two cells, or list the two cells or put in two numbers literally, although that is not advisable. =SUM(A11:A12) =SUM(A11,A12) =SUM(43,148)

the data of copied cells is distributed to the two daughter cells during prophase
What role do surface markers play in blood typing?
Different proteins cause different blood types. A and B are two different proteins, as is M and N. O is the absence.
Which cells have the function of cell membrane in all cells?
no cell acts as a cell wall. cell walls are made of a two layers of lipids.
What is the function of the plasmodesmata in plants?
The passage between two cells. Water and nutrient passages, generally.
What two things limit the size of a cell?
2 things: Surface Area and Volume Surface: how much surface area (on the plasma membrane) determines how much nutrients the cell obtains, thus controlling how much the cell can grow. Volume: as the cell grows, the volume increases, and the cell's function stability decreases, thus weakening the cell and hindering the cells growth.
