The one that would not characterize allopatric selection is : Chromosomal changes within population
in order to be characterized as allopatric selection, overlapping spatial and geographic location must happen. Which mean something that happen within population could no be characterize as it
hope this helps
Answer:
C) Release of von Willebrand factor (vWF) from the endothelium, not the epithelium.
Explanation:
Hemostasis is the physiological process of reparation and maintenance of a blood vessel to stop excess loss of blood in case of vascular injury. This process occurs in four stages:
- Vascular Injury i.e. a breach in the endothelial barrier. This results in the dislodge of endothelial cells, exposing the collagen fibers underneath.
- Vascular constriction or vasoconstriction is the constriction of the blood vessels to prevent excessive blood loss.
- Platelet plug formation involves the aggregation and adhesion of platelets to the endothelium.
- Coagulation
Platelet plug formation occurs by the adhesion of circulating platelets to the collagen fibers that have been exposed by dislodging of the endothelial cells. The endothelium, as well as the platelets release a ligand known as the von Willebrand factor (vWF). This molecule acts as a relay or bridge between the integrin receptors on the platelets and the exposed collagen fibers.
Platelets also release chemicals to attract more platelets to the wound site, resulting in more vWF release. This results in more and more platelets adhering to the endothelium, leading to platelet plug formation.

Answer:
B. Gravitational potential energy
Explanation:
An easy way to remember this is if something has the potential to fall from height, that medium will more than likely have gravitational potential energy.
Elastic EP is more so for when materials bend and warp, think of the energy in a stretched rubber band before you let it go
Vibrational energy is more along the lines of atoms and molecules which are constantly vibrating
Radiant energy is energy of electromagnetic waves, such as sunlight or radiation, etc
Answer:
Its dermal ground or vascular
