Gravitational lensing can be simply refered to as a phenomenon where a gravitational field is created by a huge matter (cluster of galaxies) in space which distort and magnifies the lights coming from another huge matter (cluster of galaxies) from a distance but on thesame line of sight. (causing a formation of arcs of light around the huge object).

Why do organisms have varying traits, like different colored eggs?
mylen [45]

the organisms have varying traits, like different colored eggs because of the natural selection.

<h3>What is the process of natural selection? </h3>

Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.

the color change of an egg occurs by natural selection and also by genetic variability. since the environment will select the best ones to survive and mutations will occur. Natural selection will forcefully change the environment causing only a few species to survive.
