Biology

OLEGan [10]3 years ago

Answer:

Explanation:

In early year the earth was devoid of free oxygen- oxygen that is not mixed with carbon and nitrogen that is needed for anearobic respiration, only the cyanobacteria releases free oxygen leading to it low concentration on earth. Because of the low concentration earth could not support life. Over the years a small portion of the ocean started releasing oxygen into the earth increasing the amount of oxygen in the planets earth. This is needed in anearobic respiration for the release of ATP,alcohol( Ethanol) and CO2

This oxygen makes the earth more suitable to accommodate complex life leading to diversification and evolution of new organisms.

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.
