Answer:
1. chondrichthyan
2 lateral line system
3. lobe fins
4 operculum
5 ray finned fish
6 swim bladder
Explanation:
A fish with a flexible cartilage skeleton is defined as a chondrichthyan
A lateral line system is a column of organs that are sensitive to small change in water pressure
Fish with strong pectoral and pelvic fins with rod-shaped bones are known as lobe fins
The operculum movement helps certain fish to breathe without swimming.
A fish with a bony skeleton and long, flexible fins is defined as ray-finned fish
A swim bladder is the gas-filled bag used in several fishes.
Where are the answers to pick from.
Answer:
Plants are able to use the energy from sunlight to produce sugars, which are a source of energy and matter. On the other hand, an animal cannot make its own food, so it eats plants and other animals.
Explanation:
This gene could be analyzed to determine its homology level with a human gene, which then could be restored in its normal expression. This strategy can restore the normal phenotype in defective human cells.
Sequence homology, which refers to the level of evolutionary relationship among genetic or proteins sequences, is a fundamental subject matter to determine gene function.
From this approach (sequence homology search), researchers can identify valuable genes involved in diseases in which the restoration of their normal expression levels can be used to restore the normal phenotype in defective cells.
In this case, the identification of a gene in cockroaches that is responsible for nerve regeneration could be used for subsequent identification of a human homologous gene sequence, which then can be restored in order to treat human paralysis.

Sand dunes are formed from wind movement. There needs to be a large amount of loose sand in an area with hardly any vegetation, enough wind to move grains of sand and some kind of obstacle to make the blowing sand lose its momentum and settle in a new place.
