All the organisms are running across a continuous evolution system and the organisms including the human beings do not fit into the classification system of the time. the classification system changes according to the changes in the organisms species and they have to be incorporated soon in new groups.
the organisms in the order Gymnophiona have no limbs. Option 3
<h3>What is Gymnophiona ?</h3>
Gymnophiona also called Apoda, area known as one of the three major orders of the class Amphibia.
Its members are known as caecilians which means “sightless” or “blind.”
Majority of the organisms in this group are limbless and wormlike amphibians that live underground in humid tropical regions throughout the world.
They are believed to have internal fertilization.
Their heads are blunt, and their skulls are bony and compact in nature.
Since they are limbless, they have no limbs
Thus, the organisms in the order Gymnophiona have no limbs. Option 3

Answer:
A. Yes, its an inherited behaviour that helps the goose and its offspring to survive.
Explanation:
Adaptation could be a trait with a functional role in an individual or animal that is maintained and has also evolved as a result of natural selection.
The male goose hissing and wing flapping is an adaptive trait of scaring away predators.
The making of replicas of the original fossils, is pretty much the say way, just different materials, in which the fossils originally have been formed and preserved.
When an organism dies, be it a plant or an animal, it gets fossilized only if very quickly after the death it is covered with sediments or mud. The sediments or the mud protect the plant or animal from the outside influences, so once it is kind of in a vacuum, or protective layer if you will, in which parts of the plant or animal that are long-lasting are preserved.
The clay and plaster used for the replica, work in the same way, because they wrap around the fossil tightly and isolate it from outside influences, with the result being different though, as they just make a copy of the fossil.
The nurse should assure the patient that black tongue is an expected side effect of taking that particular drug. The active ingredient in the drug contain bismuth. The tongue and the alimentary canal of humans contain trace amount of sulphur, when bismuth comes in contact with this sulphur, bismuth-sulphide will be formed. Bismuth-sulphide is an harmless by product, thus, the tongue discoloration observed in the patient is harmless.<span />
