Lines of cleavage are of utmost importance to surgeons, because a cut made parallel to a line of cleavage will usually remain closed with only minimal bleeding. Such a cut heals with a minimum of scarring. By contrast, a cut made at a right angle to a cleavage line will be pulled open as cut elastin fibers recoil. This cut will bleed profusely and will produce much scar tissue as it heals.

The series of cellular divisions by which the zygote becomes a multicellular embryo is known as?

The series of cellular divisions by which the zygote becomes a multicellular embryo is known as cleavage. During cleavage, the zygote undergoes multiple rapid divisions without growth in between, leading to the formation of a blastula or blastocyst.


What is the cleavage of hematite?

It has no cleavage because it has an uneven and irregular fracture.


Rhombohedral cleavage is displayed by the mineral named?

Calcite is the mineral that displays rhombohedral cleavage. Cleavage is the way a mineral breaks along certain planes of weakness, resulting in smooth, flat surfaces. In the case of calcite, it typically breaks along three cleavage planes at 75° and 105°, resulting in rhombohedral-shaped cleavage fragments.


What is the polybasic cleavage definition and how does it relate to the process of protein cleavage?

Polybasic cleavage refers to the cleavage of a protein at multiple basic amino acid residues by enzymes called proteases. This process is important for regulating protein function and activity. Protein cleavage plays a crucial role in various biological processes, such as signal transduction, protein activation, and degradation.


Cytokinesis in animal cells is called?

Cleavage furrow formation. It is the process by which the cytoplasm of a cell is divided into two daughter cells following cell division. This process involves the constriction of the cell membrane to form a furrow that eventually pinches the cell into two separate, identical daughter cells.
