D Energy input from the environment is stored in food molecules
during photosynthesis.
its correct.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment and are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Hope this helps :))
Connell's famous barnacle experiment was initiated to learn more about competitive exclusion and distribution of branacle species. Barnacle species are distributed in distinct zones on the rocky shores of the Atlantic coast. The Chthamalus in upper intertidal zone; is a smaller species and the semibalanus in low intertidal zone which is a larger species. Chthamalus found in the higher physical stress and higher temperatures because the low tide levels causes them to be exposed to the extreme outside environment for longer periods of time than the semibalanus. Additionally barnacles can only feed while submerged and the higher up shore a barnacle is, the less it can feed and grow. The experiment wanted to understand why they lived this way.
<span>Epigenesis is the term which says that an organism develops from the fertilized egg by a succession of developmental events that leads to an adult. This theory was first published by Aristotle. It became a well established and accepted theory in the late 18th century.</span>
I think the correct answer from the choices listed above is the third option. The DNA is used as a molecular clock in the sense that the <span>percent of carbon in DNA is compared between parent and offspring. Hope this answers the question. Have a nice day.</span>
