What are the economic importance of coelenterates??​
aalyn [17]

Answer: Coelenterates as a whole are of little economic importance. Seldom used as food by man, they are eagerly devoured by certain fishes and by invertebrates such as the crown of thorns starfish.

Sidana [21]

Minerals which are good conductors of electricity are described below.

Explanation:

  • metals tend to be highly efficient conductors of heat and electricity. The vast majority of elements on the periodic table are metals, and most of these fall into one of five families: alkali metals; alkaline earth metals; the very large transition metals family; and the inner transition metal families, known as the lanthanides and actinides.
  • Metals are lustrous or shiny in appearance, and malleable or ductile, meaning that they can be molded into different shapes without breaking. Despite their ductility, metals are extremely durable and have high melting and boiling points. They are excellent conductors of heat and electricity, and tend to form positive ions by losing electrons.

exis [7]

Answer:

EtBr inserts between the stacked bases in the DNA double helix.

Explanation:

  • EtBr is used for visualizing DNA bands as it fluoresces under the UV illumination.
  • EtBr is an aromatic compound that is capable of inserting itself between the stacked bases of the DNA double helix.
  • The hydrophobic environment around the base pairs where the EtBr intercalates is responsible for the fluorescence. As the EtBr molecule intercalates between these base pairs the cation of EtBr sheds the water molecules associated with it and this causes it to fluoresce under UV light as water is a quencher of fluorescence.
