Rectal bleeding of bright red blood3. Having blood in the stool and makes it look dark4. Abdominal pain5. Fatigue6. Sudden weight loss
<h2>Simple contusion </h2>
Explanation:
Simple contusion in eye
- Simple contusion is also known as bruise or commonly known as black eye which is used to describe the discoloration that occurs around an eye after a trauma to the eye or surrounding tissues
- It is caused by broken blood vessels under the surface of the skin is typically accompanied by swelling
- A serious condition that can accompany a black eye is bleeding inside the eye, in the space between the back side of the cornea and the front of the iris which is called hyphema
Scleral hemorrhage
- Scleral hemorrhage also known as subconjunctival hemorrhage
- When small and delicate blood vessels break beneath the tissue covering the white of the eye (conjunctiva), resulting eye redness then this condition is known as subconjunctival hemorrhage
- A subconjunctival hemorrhage usually is benign, causing no vision problems or significant eye discomfort despite its conspicuous appearance
- But eye redness also can be a sign of other types of potentially serious eye conditions
Answer:
the definition of migration is option B
Answer:
The correct answers are option A. "tethering proteins to the cell cortex", B. "using barriers such as tight junctions", C. "tethering proteins to the extracellular matrix", D. "forming a covalent linkage with membrane lipids", E. "tethering proteins to the surface of another cell"
Explanation:
According to the fluid-mosaic model, the components of cell membranes are in constant movement forming a barrier to avoid unwanted exterior component internalization and to avoid the loss of precious internal components. This constant movement could cause that proteins move across the plasma membrane. But, this is avoided by several mechanisms including:
A. Tethering proteins to the cell cortex. The cell cortex is a rigid structure made of actin and actomyosin. Proteins found in the plasma membrane are tethered to this structure to restrict their movement.
B. Using barriers such as tight junctions. Tight junctions are barriers found in epithelia made of claudin and occludin proteins. These barriers are impenetrable, which avoid the movement of proteins in the cell membrane.
C. Tethering proteins to the extracellular matrix. The extracellular matrix is made of several proteins and macromolecules that provide a structural and biochemical support to cells that are nearby. Proteins could be tethered to this rigid structure as well.
D. Forming a covalent linkage with membrane lipids. The proteins in the cell membrane that form a covalent linkage with membrane lipids are known as lipid-anchored proteins, or lipid-linked proteins.
E. Tethering proteins to the surface of another cell. When cell-cell communication take place it is possible that proteins in the cell membrane got tethered to the surface of the other cell.
