Answer

Answer:

  1. c) both are cold - blooded
  2. b) they live in animals' digestive systems; c) they decompose dead organisms
  3. Frogs are eukaryotic. - True; Animal cells have a cell wall. - False; Bacteria is prokaryotic. - True; Viruses can be helpful. - True; Some mammals lay eggs. - True; Speaking Spanish is inherited. - False
  4. b) evaporate the water from the solution
  5. c) coloring paper; D) bending a wire
  6. a) they both have a north and south pole.
  7. attract
  8. attract
  9. c) they cause cracks in the crust
  10. d) The cracks will continue to get larger.

Explanation:

Step1: Reptile and fish characteristics

Reptiles and fish are cold - blooded. Reptiles don't always have gills, they are vertebrates and not all live in water.

Step2: Beneficial bacteria

Bacteria in digestive systems aid digestion and decomposing dead organisms is a beneficial ecological role. Age and presence in raw foods aren't benefits.

Step3: Biological facts

Frogs are eukaryotes. Animal cells lack a cell wall. Bacteria are prokaryotes. Some viruses can be beneficial. Platypus is an egg - laying mammal. Language is not inherited.

Step4: Separating solutions

Evaporating water leaves behind dissolved substances like in lemonade - water solution. Melting sugar doesn't separate them, freezing doesn't work well.

Step5: Physical changes

Coloring paper and bending a wire are physical changes as no new substances are formed. Rusting and burning are chemical changes.

Step6: Magnet properties

Both bar and electromagnets have north and south poles. Only electromagnets can be turned off, have electrical current and use a battery.

Step7 - 8: Electric charge interactions

Opposite charges attract.

Step9: Earthquake effects

Earthquakes cause cracks in the crust. Volcanoes release ash and lava, not earthquakes. They don't cause biological weathering or create new rivers directly.

Step10: Water - ice expansion

When water freezes in cracks, it expands, making cracks larger over time.
