21 what is missing from the following food web
21. What is missing from the following food web? and cellular respiration?

  • Genetic diversity


23 what are the monomers of proteins and what bonds hold them together
23. What are the monomers of proteins, and what bonds hold them together?

  • Amino acids

  • Peptide bonds


Test review
24. Algae like Euglena and them together?cyanobacteria both undergo photosynthesis. What is the primary difference between the two organisms?

  • The presence of a nuclear membrane


25 what symbiotic relationship occurs when both partners benefit from the interaction
25. What them together?symbiotic relationship occurs when both partners benefit from the interaction?

Mutualism


26 what does crossing over lead to an increase of
26. What them together?does crossing over lead to an increase of?

Genetic Variation


Test review

27. Horses them together?are much larger now than their ancestors in the fossil record. What would be the best explanation for why horses have changed so much over millions of years?

Scorpions have changed as a result of natural selection


Test review

28. The them together?Nile River flows into the Mediterranean Sea. The Aswan High Dam contains the flow of water from the river and reduces the annual fall flooding. The floodwater is trapped behind the huge dam, allowing irrigation for agriculture. Sediments that would be washed away by the annual floods are also trapped behind the dam. The graph shows the water flow from the Nile that enters the Mediterranean Sea. How has the dam most likely affected the Mediterranean Sea Ecosystem?

Reduced nutrients from the land support fewer producers in the sea
