Answer

Brief Explanations:

  • Question 60: Genetic variation allows different bacteria to have different resistance - related genes, enabling some to survive in the presence of antibiotics.
  • Question 61: The "Ring of Fire" around the perimeter of the Pacific Ocean is known for having a high concentration of major earthquakes and volcanic eruptions due to tectonic plate activity.
  • Question 62: Oceanic plates are denser than continental plates, which causes them to subduct below the continental plates.
  • Question 63: At mid - ocean ridges (where tectonic plates move apart), new crust is formed. In the diagram, this is likely point B.
  • Question 64: The oldest rocks are found furthest from the mid - ocean ridge. In the diagram, this is likely point D.
  • Question 65: Climate change can cause habitat loss, and human activity can cause habitat alteration.
  • Question 66: Consumers cannot start to photosynthesize as they lack the necessary structures and pigments for photosynthesis.
  • Question 67: The fact that the species has not gone extinct and the behavior continues indicates that it is an effective survival behavior.
  • Question 68: Fish swimming in groups have multiple advantages including appearing as a larger fish to deter predators, improving the chances of finding a mate, and swimming more efficiently.
