Answer:
Eels are just elongated fish. Their ancestors looked like tarpon fish. Their fins were a disadvantage in tight spaces, streamlined creatures literally filled a niche. They are more related to the salmon than the pythons.
There is fossil evidence to suggest that pythons and all the other snakes may have evolved from burrowing lizards, such as the varanids. Which are more related to the geckos than to fish.
Explanation:
The confusion can be made because eeil genus name-Anguilla, comes from anguis, which on Latin means serpent.
Pythons' vestigial leg structures and snakes' similar DNA sequences with geckos both point to a common ancestor and evolution over time. These observations support the theory of evolution, demonstrating that while some traits may be lost over time, like legs in snakes, others are retained.
Vestigial structures and DNA sequences are two types of evidence that evolutionists use to support the theory of evolution. In this case, pythons have been observed to have vestigial leg bones which implies that their ancestors might have had functional legs. On the other hand, the fact that snakes have more DNA sequences in common with four-legged geckos than with legless eels could also be interpreted as evidence of a common ancestor.
Snakes and geckos, despite their very different appearances, both belong to the clade Squamata, which also includes lizards. Their DNA sequences suggest that these creatures have shared ancestry, supporting the evolutionary theory. Similarly, the vestigial structures in pythons further back up this view. Vestigial structures are remnants from an organism's ancestry. The leg bones in pythons could well be residual parts left over from their legged ancestors, as snakes are believed to have descended from lizards.
In a nutshell, both these observations tell us the same story: that current species have evolved from common ancestors in the past. Over time, some traits (like legs in the case of snakes) might have become useless and got eliminated through natural selection, while others were retained. The end result is the rich biodiversity we see around us today.

B. Logistic growth
C. Emigration
D. Immigration
Answer: C. Emigration
Explanation:
Young animals approaching maturity might do emigration, to find mates or to establish new territories. Emigration can be define as the migration or departure of individuals from their native land to the new land. The organisms usually find a suitable location where resources such as food, water and mates are available for copulation and reproducing offsprings. The increase in the population of the emigrant organisms help it to maintain their own territories against the competing members of the same population.
B. Heat equal masses of wax and chocolate and measure their temperatures when they start to melt.
C. Heat samples of wax and chocolate and use a stopwatch to time how long it takes until they start to melt.
D. Use Mohs Hardness Scale to test how easily wax and chocolate can be scratched.
