Problem: OPTIONS:
- telomeres
- glacier
- tangles
- varves
Q: Answer the following question given this paragraph: Several types of stratified deposits form in glacial regions but are not formed directly by the ice. Varves form where lakes are covered by ice in the winter. Dark, fine-grained clays sink to the bottom of the lake in winter. Melting ice in the spring brings running water that deposits lighter colored sands. Each alternating dark/light layer represents one year of deposits. Q: What type of stratified deposit is formed where lakes are covered by ice in the winter? A:
Answer: varves
Problem: OPTIONS:
- defacation
- photosynthesis
- breath
- glycolysis
Q: Answer the following question given this paragraph: Glycolysis is the first stage of cellular respiration. It takes place in the cytoplasm of the cell. The world glycolysis means "glucose splitting". That's exactly what happens in this stage. Enzymes split a molecule of glucose into two smaller molecules called pyruvate. This results in a net gain of two molecules of ATP. Other energy-storing molecules are also produced. (Their energy will be used in stage 3 to make more ATP. ) Glycolysis does not require oxygen. Anything that doesn't need oxygen is described as anaerobic . Q: What is the first stage of cellular respiration? A:
Answer: glycolysis
Problem: OPTIONS:
- actins
- hormones
- keratins
- titins
Q: Answer the following question given this paragraph: Proteins can differ from one another in the number and sequence (order) of amino acids. It is because of the side chains of the amino acids that proteins with different amino acid sequences have different shapes and different chemical properties. Small proteins can contain just a few hundred amino acids. Yeast proteins average 466 amino acids. The largest known proteins are the titins, found in muscle, which are composed from over 27,000 amino acids. Q: What are the largest known proteins? A:
Answer:
titins
