Q: Answer the following question given this paragraph: Characteristics of Amphibians As tetrapods, most amphibians are characterized by four well-developed limbs. Some species of salamanders and all caecilians are functionally limbless; their limbs are vestigial. An important characteristic of extant amphibians is a moist, permeable skin that is achieved via mucus glands that keep the skin moist; thus, exchange of oxygen and carbon dioxide with the environment can take place through it ( cutaneous respiration). Additional characteristics of amphibians include pedicellate teethteeth in which the root and crown are calcified, separated by a zone of noncalcified tissueand a papilla amphibiorum and papilla basilaris, structures of the inner ear that are sensitive to frequencies below and above 10,00 hertz, respectively. Amphibians also have an auricular operculum, which is an extra bone in the ear that transmits sounds to the inner ear. All extant adult amphibians are carnivorous, and some terrestrial amphibians have a sticky tongue that is used to capture prey. Q: Amphibians have permeable skin which allows for the exchange of oxygen and carbon dioxide, what is this "breathing called?" A:

OPTIONS:
- variant respiration
- benign respiration
- aquatic respiration
- cutaneous respiration

A: cutaneous respiration

Q: Answer the following question given this paragraph: Q: What's the name for the process where pollen is transferred to the ovules of a seed plant? A:

OPTIONS:
- combination
- condensation
- hibernation
- pollination

A: pollination

Q: Answer the following question given this paragraph: Like density, the pressure of the air decreases with altitude. There is less air pressing down from above the higher up you go. Look at the bottle pictured below ( Figure below ). It was drained by a hiker at the top of a mountain. Then the hiker screwed the cap on the bottle and carried it down to sea level. At the lower altitude, air pressure crushed it. Can you explain why?. Q: How does air pressure change as altitude increases? A:

OPTIONS:
- goes up and down
- stays the same
- It increases
- it decreases

A: it decreases

Q: Answer the following question given this paragraph: Q: What are fibers that depend on aerobic respiration called? A:

OPTIONS:
- hydrogen fibers
- evaporative fibers
- fragile fibers
- oxidative fibers

A:
oxidative fibers
