The appropriate response is A. Gastrulation is a stage ahead of schedule in the embryonic improvement of most creatures amid which the single-layered blastula is rearranged into a trilaminate (three-layered) structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm.
Microvilli are the structures of fingerlike projections that greatly increase the absorbing surface of the cells.
<h3>What is Microvilli? </h3>
Microvilli are membrane protrusions that resemble fingers and are sustained by the actin cytoskeleton. They are present in practically all cell types. An increasing amount of research indicates that the highly curved membranes of the dynamic lymphocyte microvilli play a critical role in signal transduction that triggers immunological responses.
The examination of the process that generates curvature and its functional implications in signaling, however, was impeded by difficulties in altering local membrane curvature and tracking the high dynamicity of microvilli. Recent developments in adaptive super-resolution microscopy have helped to partially overcome these technological obstacles.
Therefore the structure that increases the absorbing surface area is called microvilli.

Answer:
You can measure mineral hardness with The Mohs' Scale.
Hope this helped :)
This process is called endocytosis. Endo- means: within, inner, absorbing, or containing
I'm not sure if there were choices here but I would fill in something like "logically" or "scientifically".
Hope that helps.
