Answer: C). A biozone can help trace the path of evolution over time.
Biozone is a stratigraphic unit which contains fossils in layers of strata existed in a particular geologic period. It is named as biozone because it depicts the number of biological taxa existed in particular strata. Therefore, the variation in features within taxonomic groups in biozones can give indication of evolution with respect to time.
The sun feeds the plants through the process of photosynthesis. the animals gain energy and grow by eating those plants. other animals eat those animals and gain energy and grow. the cycle is never ending and all begins with the sun. without it, the plants and animals wouldnt get food and die off.
Answer:
<u>Option-(True):</u> The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent with modification.
Explanation:
<u>Evolution and patterns of evolution:</u>
The phenomenon of evolution is very interesting as it can any two different species back to a common origin or ancestors. While the process of evolution does not occur in few years or centuries, as it takes millions of years for any specie to evolve from a less developed form of body or any system to a more complex or advance form.
Now, evolution occurs in many forms or patterns. As it species can originate from a single ancestor or descendant, while the evolution can occur inside the organism may occur in different patterns. These patterns are as follows:
- <u>Divergent Evolution:</u>The divergent evolution occurs when the species originated from a single ancestor or descendant results in different forms of organisms. As it brings diversity among the species belonging to same ancestors or origin. For example, the humans and apes.
- <u>Convergent Evolution: </u>The convergent evolution takes place inside the number of species when they are originated from the different species but they share the same medium or region to live in and share some of the similar resources between them. For example, The whales are mammals but they too live with the fish species inside the water.
- <u>Parallel Evolution:</u>When the evolved organisms or species are related to the different ancestors or descendants, as they share they do not share the same niche(way of life), as the species are unrelated to one another.
Answer:
Watson and Crick were able to develop a more accurate molecular structure because they had access to x-ray crystallography! Pauling didn't actually failed, he just did't have the same means!
Explanation:
By the way, is now known that the real discovery of DNA molecule was made by Rosalind Franklin. Any doubts you can send me a message!
