Germ layers

Explanation:

Gastrulation is the process of formation of the three germ layers from a blastula. The gastrulation starts after the 3rd week of fertilization. In this process, the blastula forms a bilayer disc. This bilayer disc consisting of outer epiblast and inner hypoblast. Then this bilayer disc transforms into three layered discs.  

These three layers are ectoderm, mesoderm, endoderm, and are the 3 germ layers. The ectoderm develops from the epiblast, endoderm arises from the hypoblast, and the mesoderm is the middle layer which develops in between the epiblast and hypoblast. The ectoderm is the outer layer and the endodermis the inner germ layer. Then different organs develop from these three germ layers.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

there’s no image attached but i can if you want: )
