Answer the following question given this paragraph: Ancestors of mammals evolved close to 300 million years ago. They were amniotes called synapsids. Figure below shows how modern mammals evolved from synapsids. The stages of evolution from synapsids to mammals are described below. Q: How long ago did the ancestors of mammals evolve? Choices: - 10 million - 50,900 million years - 100 million - 300 million years A:
300 million years
Answer the following question given this paragraph: Yes, we will use up all our gasoline eventually. Gasoline is derived from oil. Oil deposits were formed over hundreds of millions of years. They cannot be quickly replenished. Oil is an example of a nonrenewable resource. Q: Gasoline is derived from which other liquid? Choices: - liquid propane - water - carbon - oil A:
oil
Q: Answer the following question given this paragraph: Groundwater deposits the material in caves as stalactites, stalagmites, and columns. Q: What helps deposit the material in caves as stalactites, stalagmites, and columns Choices: - gas - wastewater - precipitation - groundwater A:
A: groundwater
Question: Answer the following question given this paragraph: Reverse transcription also occurs with retrotransposons and during telomere synthesis in eukaryotes. Retrotransposons are self-replicating segments of eukaryotic genomes that use reverse transcriptase to move from one position in the genome to another via a RNA intermediate. A telomere is a region of repetitive noncoding nucleotide sequences at each end of a chromosome. These sequences protect the end of the chromosome from deterioration or from fusion with neighboring chromosomes. Each time DNA is replicated, small segments of DNA from the ends of the chromosome is lost. Telomerase is a reverse transcriptase that uses an RNA intermediate to elongate the 3' end of DNA strands in the telomere regions after each replication cycle. Q: What is a region of repetitive noncoding nucleotide sequences at each end of a chromosome? Choices: - diploid - cellular - cytoskeleton - telomere A:
Answer: telomere

Answer the following question given this paragraph: After a polypeptide chain is synthesized, it may undergo additional processes. For example, it may assume a folded shape due to interactions among its amino acids. It may also bind with other polypeptides or with different types of molecules, such as lipids or carbohydrates. Many proteins travel to the Golgi apparatus to be modified for the specific job they will do. You can see how this occurs by watching the animation at this link: http://vcell. ndsu. edu/animations/proteinmodification/movie-flash. htm . Q: What part of a cell do proteins travel to to be modified for the specific job they will do? Choices: - plasma membrane - lysosome - nucleus - golgi apparatus A:
**Answer**
golgi apparatus
Answer the following question given this paragraph: An analog signal consists of continuously changing voltage in a circuit. For example, microphones encode sounds as analog signals. Q: What is continuously changing within a circuit in an analog signal? Choices: - energy - frequency - amplitude - voltage A:
voltage
