Evolution is the process by which species developed and diversified over the course of Earth's history. All life on Earth started
from simple, single-celled prokaryotes, but some species are more closely related than others. Scientists can find clues to
these close evolutionary relationships by looking for common characteristics between organisms.
Based on their anatomical similarities, which three of these organisms share a close evolutionary relationship?
snake
horse
ladybug
human
bacteria

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.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
