What is the copying process by which a cell duplicates its dna

The correct answer will be-DNA replication.

Explanation:

DNA replication is the process which facilitates the cell to form an exact copy of the genetic material called DNA. This process takes place during the Synthesis phase of the cell cycle.

DNA replication is a complex process which is mediated by the enzymes- DNA helicase, DNA primase, DNA polymerase and DNA ligase.   The formation of the new DNA strand is an energy-dependent process that is it requires the ATP to bind new nucleotide to the strand.

Thus, DNA replication is the correct answer.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
