<span>The three groups of amphibians: Frogs, Salamanders, Caecilians are different when they reach adulthood. Frogs have four legs with strong hind legs and no tails. Salamanders have tails and four short, weak legs that cause them to walk instead of jump. Lastly, Cacilians have no legs and are burrowing animals.
Amphibians must live in moist environments because they loose water through their thin skin. They need to be near water to replenish the lost water. Also their skin helps them breathe and they can get oxygen from the water.</span>

air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung
Explanation:
Answer:
E. 1/16
Explanation:
In a duplicate dominant epistasis, when one locus presents a dominant genotype and the other presents a recessive genotype, the dominant one hides the effective of the recessive gene. Therefore, a recessive phenotype will only be observed when both genes are recessive homozygous (aabb).
Assuming a doubly-heterozygous mating (AaBb x AaBb), the probability that both genes are recessive homozygous is:
1/16 of offspring are expected to show the recessive phenotype.
