Diapedesis is the movement of white blood cells through intact blood vessel walls into surrounding body tissue. It typically hap
liq [111]

Answer:

Cell adhesion molecules would help white blood cells to stick to the wall of the blood vessel, so they can permeate across the wall and go into the underlying injured tissue.

Explanation:

The cell adhesion molecules, also called CAMs, are a type of cell adhesion proteins on the cell's surface, they take part in the binding of other types of cells and work together with the extracellular matrix in the process of cell adhesion.  

Long story short, the protein helps cells stick together or to the surrounding tissues, thus helping on the maintenance of tissue structure and function. In fully grown mammals (including humans), CAMs play an important and key role in creating force and movement, thus assuring the organs are able to execute their function.

In their role as "molecular glue", CAMs are important participants in the cellular mechanisms of growth, contact inhibition, apoptosis and diapedesis, and when their behavior goes haywire, they are associated with afflictions going from frostbite to cancer.

Number the steps of the binary fission process in the correct order. . Step 1 Cell wall or membrane forms. 2. Step 2 Cell grows
vampirchik [111]
The answer is:
<span>Step 1 Genetic material duplicates.
</span>Step 2 Cell grows in size and other <span>organelles duplicate.
</span><span>Step 3 Cell wall or membrane forms.
</span>Step 4 Cells separate.

Binary fission is a type of cell division characteristic for prokaryotic cells. In this process, after the cell reaches its maximum size, the genetic material starts to duplicate. These two copies of genetic material are now connected to plasma membrane. The cell begins to grow in size and thus separate those two copies of genetic material. Other organelles are duplicated, too. Next, a new cell wall or cell membrane starts to grow in the middle of the cell leading to the separation of the cell.
