4 4pts. Match the following phrases with either OPERONS or FEEDBACK INHIBITION. Do this by writing two lists, one with OPERONS at the top and the other with FEEDBACK INHIBITION. • Regulation at the protein level • Conserves energy, nucleotides, amino acids • Regulation at the DNA or gene level • Conserves some energy • Goes into effect fairly quickly . Eventually shuts down gene expression • Uses end product to regulate enzymes . Can allow bacteria to respond to...
please answer in detailed explanation! What is a chemolithotroph? How does a lithotroph get energy? Explain how the electron transport chain of the lithotrophs works: describe specifically how it is used to extract energy and reducing power from H,, HS and from Fe 2. Include drawings. What types of environments do these organisms tend to live in? How efficient is their metabolism, relative to organotrophs? Bonus: Give the genus and species name of one organism of each type: hydrogen oxidizer,...

What are the characteristics of life? Give an example of a living organism and explain why it is considered alive?
g. Explain the positive feedback and spreading concept for constitutive heterochromatin? What is the writer of histone modifications that is thought to be fundamental to constitutive heterochromatin? What is the histone mark that it writes? What is a main reader of this mark that helps to spread the mark and how does this spreading take place? 5 pts
