Explain in at least 50 words why.arrow_forwardYou are studying the evolution of species. After performing DNA analysis, he discovers a gene that is conserved from yeast to humans. In which cellular processes is this gene most like to be involved? Could this gene have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.arrow_forward
- “What is the origin of life or the main ancestor of all organisms?”, what would be your answer and why?arrow_forwardScientists classify living things in order to organize the astonishing diversity of life on Earth. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related. In other words, they are descendants of a common ancestor in the past. As we said earlier in our discussion, there are species that needs to be named and some are to be discovered. However, with the current environmental situation we have at the present (pollution, exploitation of resources, forest fires, and others), these species that are yet to be identified are being endangered and at the verge of extinction. As a matter of fact, the University of Turku reported last July 1, 2020 that there are 15 million estimated different species living in our planet but 2 million of them are currently known to science. Discovering these remaining species is important for them to be protected. Also,…arrow_forward1. Design a cell/a system of cells using the following to show explicitly.

- Which of the following illustrates the unity observed in organisms with a common ancestor? Flamingos and penguins are different colors. The gene for the human hormone insulin can be inserted into bacteria, and the resulting bacteria can use the gene to produce functional insulin. A robin can fly, but a penguin cannot. Fungi tend to absorb nutrients from other organisms, while animals consume their food.
