Q: Q: Prokaryotic cells can only regulate gene expression by controlling the amount of what? Read this paragraph and choose the correct option from the provided answers: Evolution of Gene Regulation Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes. A nuclear region that contains the DNA was formed. Transcription and translation were physically separated into two different cellular compartments. It therefore became possible to control gene expression by regulating transcription in the nucleus, and also by controlling the RNA levels and protein translation present outside the nucleus. Some cellular processes arose from the need of the organism to defend itself. Cellular processes such as gene silencing developed to protect the cell from viral or parasitic infections. If the cell could quickly shut off gene expression for a short period of time, it would be able to survive an infection when other organisms could not. Therefore, the organism evolved a new process that helped it survive, and it was able to pass this new development to offspring. Choices: - folding - translation - RNA processing - transcription A:
A: transcription

Q: Q: What term describes the ability of matter to combine chemically with other substances? Read this paragraph and choose the correct option from the provided answers: Reactivity is the ability of matter to combine chemically with other substances. For example, iron is highly reactive with oxygen. When it combines with oxygen, it forms the reddish powder called rust (see Figure below ). Rust is not iron but an entirely different substance that consists of both iron and oxygen. Choices: - oxidation - Diffusion - permeability - reactivity A:
A: reactivity

Q: Q: What celestial bodies are born in clouds of gas and dust called nebulas? Read this paragraph and choose the correct option from the provided answers: Stars are born in clouds of gas and dust called nebulas. Our Sun and solar system formed out of a nebula. A nebula is shown in Figure below . In Figure above , the fuzzy area beneath the central three stars contains the Orion nebula. Choices: - planets - comets - galaxies - stars A:
