What is the purpose of the reflective material in the choroid coat? what is it called?

Purpose: to impart better night vision to nocturnal animals by increasing the available light for photoreceptors.

It is called "tapetum lucidum".

Explanation:

The reflective material in the choroid coat of some nocturnal vertebrates is called "tapetum lucidum". Its function is to improve the night vision of nocturnal animals. The tapetum lucidum serves to reflect the dim light available in the night. The reflected light re-stimulates the photoreceptor cells present in the retina. This increases the available light for night vision.

Tapetum lucidum makes the eyes of nocturnal mammals to shine at night.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
