There are four steps in bacterial conjugation. the second step is missing in this list
.1. special sex pilus connects two cells.
2.
3. each cell makes a complementary dna strand.
4. the cells separate.
which is the missing step for the process of conjugation described?

2. The Fusion of cell membranes and transfer of single strand of plasmid DNA of donor cell.

Explanation:

When one bacterium transfers its genetic material through direct contact to others. The bacterium transfers its genetic material called donor cell and one serves it called recipient cell.

There are mainly four steps in this process-

1. Connecting sex pilus to recipient cell by donor cell.

2. The Fusion of cell membranes and transfer of single strand of DNA to the recipient cell.

3. Each bacterium cell makes a complementary DNA strand.

4. Both bacterium cells separates.

explanation:

yooptfrhtr

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.
