Which statement best compares frogs and toads with salamanders?
frogs and toads lose their tails as they develop into adults, but salamanders keep their tails.
salamanders have lungs from the time they hatch, but frogs and toads have gills when they first hatch.
frog and toad eggs are covered in a soft, jellylike substance, but salamander eggs are covered in a hard shell.
salamander offspring are born with long legs that eventually shorten, but frogs and toads are born without legs.

Frogs and toads lose their tails as they develop into adults, but salamanders keep their tails

Explanation:

The salamanders, frogs, and toads are part of the amphibian family. They all live in both water and land. The water is still crucial for their live, despite them being relatively well developed for terrestrial live, with the biggest importance being that their offspring needs it in order to develop. The salamander offspring has only front limbs and tail, thus it can not live on land until it is fully developed, while the frog and toad offspring doesn't have any limbs at the start, only tail, thus not being able to even come out of the water. As they mature, the salamander offspring develops hind limbs as well, while retaining the tail. The frog and toad offspring develops front and back limbs, but its loses its tail.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
