Q: All metabolic functions carried out by a prokaryote take place in the plasma membrane or where else? Read this paragraph and choose the correct option from the provided answers: The bacterium in Figure above is a prokaryote. Prokaryotes are microscopic organisms that have neither a membrane-bound nucleus nor membrane-bound organelles. Some cell biologists consider the term "organelle" to describe membrane-bound structures only, whereas other cell biologists define organelles as discrete structures that have a specialized function. Prokaryotes have ribosomes, which are not surrounded by a membrane but do have a specialized function, and could therefore be considered organelles. All metabolic functions carried out by a prokaryote take place in the plasma membrane or the cytosol. Choices: - extracellular - Shell - mitochondrial - cytosol A:
**Answer**
cytosol

Q: What are the two types of properties that matter has? Read this paragraph and choose the correct option from the provided answers: Matter has both physical and chemical properties. Physical properties can be measured or observed without matter changing to a different substance. Choices: - nature and purpose - composition and weight - size and shape - physical and chemical A:
**Answer**
physical and chemical

Q: What is regulated to ensure that the correct proteins are made? Read this paragraph and choose the correct option from the provided answers: Gene expression is regulated to ensure that the correct proteins are made when and where they are needed. Regulation may occur at any point in the expression of a gene, from the start of transcription to the processing of a protein after translation. The focus in this lesson is the regulation of transcription. Choices: - acids expression - variation expression - Fat expression - gene expression A:
**Answer**
gene expression

Q: A supervolcano that may have killed all but 10,000 humans resulted in what phenomenon, lasting up to a decade? Read this paragraph and choose the correct option from the provided answers: A supervolcano eruption took place at Lake Toba in northern Sumatra about 75,000 years ago ( Figure below ). This was the largest eruption in the past 25 million years. As much as 2,800 cubic kilometers of material was ejected into the atmosphere. The result was a 6- to 10-year volcanic winter. Some scientists think that only 10,000 humans survived worldwide. The numbers of other mammals also plummeted. Choices: - volcano fall - volcanic summer - volcano spring - volcanic winter A:
**Answer**
volcanic winter
